Note: The procedures that follow are generic for all NEX852 models 2.1 Before You Begin Ensure you have a stable, clean working environment. Dust and dirt can get into components and cause a malfunction. Use containers to keep small components separated. Adequate lighting and proper tools can prevent you from accidentally damaging the internal components. Most of the procedures that follow require only a few simple tools, including the following: Š A Phillips screwdriver Š A flat-tipped screwdriver Š A set of jewelers Screwdrivers Š A grounding strap Š An anti-static pad Using your fingers can disconnect most of the connections. It is recommended that you do not use needle-nosed pliers to disconnect connections as these can damage the soft metal or plastic parts of the connectors. Before working on internal components, make sure that the power is off. Ground yourself before touching any internal components, by touching a metal object. Static electricity can damage many of the electronic components. Humid environment tend to have less static electricity than dry environments. A grounding strap is warranted whenever danger of static electricity exists. 2.2 Precautions Computer components and electronic circuit boards can be damaged by discharges of static electricity. Working on the computers that are still connected to a power supply can be extremely dangerous. Follow the guidelines below to avoid damage to your computer or yourself: Š Always disconnect the unit from the power outlet whenever you are working inside the case. Š If possible, wear a grounded wrist strap when you are working inside the computer case. Alternatively, discharge any static electricity by touching the bare metal chassis of the unit case, or the bare metal body of any other grounded appliance. Š Hold electronic circuit boards (such as the NEX852 board) by the edges only. Do not touch the components on the board unless it is necessary to do so. Don’t flex or stress the circuit board. Š Leave all components inside the static-proof packaging that they shipped with until they are ready for installation. Š Use correct screws and do not over tighten screws. 14 2.3 Setting Jumpers A jumper is the simplest kind of electric switch. It consists of two metal pins and a cap. When setting the jumpers, ensure that the jumper caps are placed on the correct pins. When the jumper cap is placed on both pins, the jumper is SHORT. If you remove the jumper cap, or place the jumper cap on just one pin, the jumper is OPEN. Please see the following illustrations The illustrations on the right show a 2-pin jumper. When the jumper cap is placed on both pins, the jumper is SHORT. If you remove the jumper cap, or place the jumper cap on just one pin, the jumper is OPEN. Open (Off) Short (On) These illustrations show a 3-pin jumper. Pins 1 and 2 are SHORT.

Make sure the two handles of the DIMM sockets are in the “open” position, i.e. the handles stay outward. Figure3-1: How to Install DIMM (1) 2. Slowly slide the DIMM modules along the plastic guides in the both ends of the socket. Figure 3-2: How to Install DIMM (2) 30 3. Then press the DIMM module down right into the socket, until a click is heard. That means the two handles automatically locked the memory modules into the right position of the DIMM socket. Figure 3-3: How to Install DIMM (3) 4. To take away the memory module, just push the both handles outward, the memory module will be ejected by the mechanism in the socket. Figure 3-4: How to Install DIMM (4) 31 3.3 Installing Compact Flash 1. To install a Compact Flash memory card into NEX852VL2, align the notches on the card with the Com- pact Flash socket in the NEX852VL2. Then firmly insert the card into the socket until it is completely seated. Figure 3-5: How to Install Compact Flash Memory (1) 2. To remove the Compact Flash memory card from NEX852VL2, pull out the memory card from the Com- pact Flash socket.

The current BIOS setup pictures in the chapter is for reference only, which may change by the BIOS modification in the future. Users can download any major updated items or reversion from NEXCOM web site http://www.nexcom.com.tw. If any unclear message occurs, please contact NEXCOM customer service representative for help or log onto http://www.nexcom.com.tw/contact/contact.htm. 4.1 About the BIOS The BIOS (Basic Input and Output System) Setup program is a menu driven utility that enables you to make changes to the system configuration and tailor your system to suit your individual work needs. It is a ROM-based configuration utility that displays the system’s configuration status and provides you with a tool to set system parameters. These parameters are stored in non-volatile battery-backed-up CMOS RAM that saves this information even when the power is turned off. When the system is turned back on, the system is configured with the values found in CMOS. With easy-to-use pull down menus, you can configure such items as: Š Hard drives, diskette drives, and peripherals Š Video display type and display options Š Password protection from unauthorized use Š Power management features The settings made in the Setup program intimately affect how the computer performs. It is important, therefore, first to try to understand all the Setup options, and second, to make settings appropriate for the way you use the computer. 4.2 When to Run BIOS This program should be executed under the following conditions: Š When changing the system configuration Š When a configuration error is detected by the system and you are prompted to make changes to the Setup program Š When resetting the system clock Š When setting the CPU clock speed so that it automatically runs either fast or slow Š When redefining the communication ports to prevent any conflicts Š When making changes to the Power Management configuration Š When changing the password or making other changes to the security setup Normally, CMOS setup is needed when the system hardware is not consistent with the information con- tained in the CMOS RAM, whenever the CMOS RAM has lost power, or the system features need to be changed. 36 4.3 Entering Setup When the system is powered on, the BIOS will enter the Power-On Self Test (POST) routines. These routines perform various diagnostic checks; if an error is encountered, the error will be reported in one of two different ways: Š If the error occurs before the display device is initialized, a series of beeps will be transmitted. Š If the error occurs after the display device is initialized, the screen will display the error message. Powering on the computer and immediately pressing allows you to enter Setup. Another way to enter Setup is to power on the computer and wait for the following message during the POST: TO ENTER SETUP BEFORE BOOT PRESS OR KEY Press the key or press the , , and keys to enter Setup: 4.4 The Main Menu Once you enter Award BIOS CMOS Setup Utility, the Main Menu (Figure 1) will appear on the screen. The main menu allows you to select from ten setup functions and two exit choices. Use arrow keys to select among the items and press to accept or enter the sub-menu.

While Award has designed the custom BIOS to maximize performance, the factory has the option to change these defaults to meet their needs. Set Password Enables you to change, set, or disable the supervisor or user password. Save & Exit Setup Saves CMOS value changes to CMOS and exits setup Exit Without Saving Ignores all CMOS value changes and exits setup. 4.5 Getting Help Main Menu The on-line description of the highlighted setup function is displayed at the bottom of the screen. Status Page Setup Menu/Option Page Setup Menu Press F1 to pop up a small help window that describes the appropriate keys to use and the possible selections for the highlighted item. To exit the Help Window press or . 38 4.6 Control Keys The table below lists the keys that help you navigate the setup program. Table 4-1: BIOS Control Keys 39 4.7 Standard CMOS Features Selecting Standard CMOS Features on the main program screen displays the following menu: Figure 4-2: BIOS – Standard CMOS Features The Standard CMOS Setup utility is used to configure the following features: Date (mm:dd:yy) The BIOS determines the day of the week from the other data information. This field is for information only. Press the left or right arrow key to move to the desired field (date, month, year). Press the PgUp or PgDn key to increment the setting, or type the desired value into the field. Time (hh:mm:ss) The time format is based on the 24-hour military time clock. For example, 1 p.m. is 13:00:00. Press the left or right arrow key to move to the desired field. Press the PgUp or Pg Dn key to increment the setting, or type the desired value into the field. IDE Devices (Primary/Secondary Master/Slave) Your computer has two IDE channels (Primary and Secondary) and each channel can be installed with one or two devices (Master and Slave). Use these items to configure each device on the IDE channel. If you leave this item at Auto, the system will automatically detect and configure any IDE devices it finds. If it fails to find 40 a hard disk, change the value to Manual and then manually configure the drive by entering the characteristics of the drive in the items below: Š Capacity Approximate hard disk drive capacity Š Cylinder Number of cylinders Š Head Number of heads Š Precomp Write pre-compensation cylinder Š Landing Zone Landing zone Š Sector Number of sector Refer to your drive’s documentation or look on the drive if you need to obtain this information. If no device is installed, change the value to None. Drive A Select this field to the type of floppy disk drive installed in your system. The choices are: Š None No floppy drive installed Š 360K, 5.25 in 5-1/4 inch PC type standard drive; 360 kilobyte capacity Š 1. 2M, 5.25 in 5-1/4 inch AT-type high-density drive; 1.2 megabyte capacity Š 720K, 3.5 in 3-1/2 inch double-sided drive; 720 kilobyte capacity Š 1.44M, 3.5 in 3-1/2 inch double-sided drive; 1.44 megabyte capacity Š 2. 88M, 3.5 in 3-1/2 inch double-sided drive; 2.88 megabyte capacity Note: The None option could be used for diskless workstations. Floppy 3 Mode Support Floppy 3 mode refers to 3.5” diskette with a capacity of 1.2MB. This mode is sometimes used in Japan. Video Set this field to the type of graphics card installed in your system. If you are using a BGA or higher resolution card, choose the EGA/VGA option. The options are: Š EGA/VGA Enhanced Graphics Adapter/Video Graphics Array. For EGA, VGA, SEGA or PGA monitor adapters Š CGA40 Color Graphics Adapter, power up in 40 column mode Š CGA80 Color Graphics Adapter, power up in 80 column mode Š MONO Monochrome adapter, includes high resolution monochrome adapters Halt On During the Power-On Self-Test (POST), the computer stops if the BIOS detect a hardware error. This setting determines which type of error will cause the system to halt during boot. The options are: 41 Š All Error: Whenever the BIOS detects a non-fatal error, the system will be stopped and you will be prompted. Š No Errors: The system boot will not stop for any error that may be detected. Š All, But Keyboard: The system boot will not stop for a keyboard error, but it will stop for all others. Š All, But Diskette: The system boot will not stop for a disk error, but it will stop for all others. Š All, But Disk/Key: The system boot will not stop for a keyboard or disk error, but it will stop for all others. After you have made your selections in the Standard CMOS Setup screen, press to go back to the main screen. 4.8 Advanced BIOS Features Selecting Advanced BIOS Feature on the main program screen displays this menu, which allows you to define advanced information about your system. You can make modifications to most of these items to improve your system performance or set up system features according to your preference, without causing fatal errors to your system. Figure 4-3: BIOS – Advanced BIOS Features The following explains the options for each feature: Virus Warning Allow you to choose the Virus Warning feature for IDE Hard Disk boot sector protection. If this function is enabled and someone attempts to write data into this area, BIOS will show a warning message on screen and an alarm will beep. 42 Š Enabled: Activates automatically when the system boots up causing the following warning !WARNING! Disk boot sector is to be modified Type “Y” to accept write or “N” to abort write Award Software, Inc. message to appear when anything attempts to access the boot sector or hard disk partition table: Š Disabled: No warning message will appear when an attempt is made to access the boot sector or hard disk partition table. Note: This function is available only for DOS and other operating systems that do not trap INT13. For complete protection against viruses, install virus software in your operating system and update the virus definitions regularly. Many disk diagnostic programs that access the boot sector table can trigger the virus warning message. If you plan to run such a program, we recommend that you disable the virus warning. CPU L1 and L2 Cache memory is an additional memory that is much faster than conventional DRAM (system memory). This BIOS feature is used to enable or disable the processor's Level 1 and Level 2 cache. Naturally, the default and recommended setting is Enabled. First/Second/Third Boot Device BIOS attempts to load the operating system from the devices in the sequence selected. The available choices are: Floppy, LS120, HDD-0, SCSI, CDROM, HDD-1, HDD-2, HDD-3, ZIP100, USB-FDD, USB- ZIP, USB-CDROM, USB-HDD, LAN, and Disabled. Boot Up Floppy Seek Enable this to allow the system to search for floppy drives during the POST. Disable this item to boot faster. Boot Up NumLock Status Toggle between On or Off to control the state of the NumLock key when the system boot. If On, the numeric keypad is in numeric mode. If Off, the numeric keypad is in cursor control mode. Typematic Rate Setting 43 If set to Enabled, enables you to set the Typematic Rate and Typematic Delay. When Disabled, the follow- ing two items (Typematic Rate and Typematic Delay) are irrelevant. Keystroke repeats at a rate determined by the keyboard controller in your system. � Typematic Rate (Chars/Sec): When the typematic rate setting is Enabled, you can select a typematic rate (the rate at which character repeats when you hold down a key) of 6, 8, 10, 12, 15, 20, 24, or 30 characters per second. � Typematic Delay (Msec): This setting controls the time between the display of the first character and successive characters. There are four delay choices: 250ms, 500ms, 750ms and 1000ms. Security Option Enables you to select whether the password is required every time the system boots or only when you enter Setup. � System: The system will not boot and access to Setup will be denied if the correct password is not entered at the prompt. � Setup: The system will boot, but access to Setup will be denied if the correct password is not entered at setup. MPS Version Control for OS This feature is only applicable to multiprocessor motherboards as it specifies the version of the Multi- Processor Specification (MPS) that the motherboard will use. The MPS is a specification by which PC manufacturers design and build Intel architecture systems with two or more processors. MPS version 1.4 is required for a motherboard to support a bridgeless secondary PCI bus. OS Select for DRAM>64MB Set to OS2 if the system memory size is greater than 64 MB and the operating system is OS/2, otherwise select non-OS2 option. Spread Spectrum The BIOS usually offers two levels of modulation - 0.25% or 0.5%. The greater the modulation, the greater the reduction of EMI. Therefore, if you need to significantly reduce your motherboard's EMI, a modulation of 0.5% is recommended. In most conditions, frequency modulation via this feature should not cause any problems. However, system stability may be slightly compromised in certain situations. For example, this BIOS feature may cause improper functioning of timing-critical devices like clock-sensitive SCSI devices. Spread Spectrum can also cause problems with overclocked systems, especially those that have been taken to extremes. Even a slight modulation of frequency may cause the processor or any other overclocked components of the system to fail, leading to very predictable consequences. 44 Therefore, it is recommended that you disable this feature if you are overclocking your system. The risk of crashing your system is not worth the reduction in EMI. Of course, if EMI reduction is important to you, enable this feature by all means. But you should reduce the clock speed a little to provide a margin of safety. After you have made your selections in the Advanced BIOS Features setup, press to go back to the main screen. 4.9 Advanced Chipset Features Since the features in this section are related to the chipset in the CPU board and all are optimized, you are not recommended to change the default settings in the setup table, unless you understand the chipset features. This section allows you to configure the system based on the specific features of the installed chipset. This chipset manage bus speeds and access to system memory resources, such as DRAM and the exter- nal cache. It also coordinates communications between the conventional ISA bus and the PCI bus. The default settings have been chosen because they provide the best operating conditions for your system. The only time you might consider making any changes would be if you discovered that data was being lost while using your system. The first chipset settings deal with CPU access to dynamic random access memory (DRAM). The default timings have been carefully chosen and should only be altered if data is being lost. Such a scenario might well occur if your system has mixed speed DRAM chips installed so that greater delays may be required to preserve the integrity of the data held in the slower memory chips. Selecting Advanced Chipset Features on the main program screen displays this menu: Figure 4-4: BIOS – Advanced Chipset Features 45 System BIOS cacheable Selecting Enabled allows caching of the system BIOS ROM at F0000h-FFFFFh, resulting in better system performance. However, if any program writes to this memory area, a system error may result. The available choices are Enabled, Disabled. Video BIOS Cacheable Selecting Enabled allows caching of the video BIOS ROM at C0000h, resulting in better video performance. However, if any program writes to this memory area, a system error may result. The choices: Enabled, Disabled. Memory Hole At 15M – 16M In order to improve performance, certain space in memory is reserved for ISA cards; This memory must be mapped into the memory. The choices: Enabled, Disabled. Delayed Transaction The chipset has an embedded 32-bit posted write buffer to support delay transactions cycles. Select En- abled to support compliance with PCI specification version 2.1. On-Chip VGA By default, the On-Chip VGA or chipset-integrated VGA is Enabled. On-Chip Frame Buffer Size The On-Chip Frame Buffer Size can be set as 1, 4, 8, 16 or 32MB. This memory is shared with the system memory. Boot Display Boot Display determines the display output device where the system boots. The options are Auto, CRT, LFP, and CRT+LFP. Panel Type This field allows user to decide the LVDS panel resolution. Please refer to the BIOS for the resolution. After you have made your selections in the Advanced Chipset Features setup, press to go back to the main screen. 46 4.10 Integrated Peripherals Figure 4-5: BIOS – Integrated Peripherals OnChip IDE Device Select this item to setup the IDE device features. When you select this item, the following menu shows: Figure 4-6: BIOS – OnChip IDE Device On-Chip Primary/Secondary PCI IDE The system chipset contains a PCI IDE interface with support for two IDE channels. Select Enabled to activate the primary and/or secondary IDE interface. Select Disabled to deactivate this interface, if you install a primary and/or secondary add-in IDE interface. 47 IDE Primary/Secondary Master/Slave PIO The four IDE PIC (Programmable Input/Output) fields let you set a PIC mode (0-1) for each of the four IDE devices that the onboard IDE interface supports. Modes 0 through 4 provide successively increased performance. In Auto mode, the system automatically determines the best mode for each device. The choices are: Auto, Mode 0, Mode 1, Mode 2, Mode 3, and Mode 4. IDE Primary/Secondary Master/Slave UDMA Ultra DMA implementation is possible only if your IDE hard drive supports it and the operating environment includes a DMA driver (Windows 95 OSR2 or a third-party IDE bus master driver). If your hard drive and your system software both support Ultra DMA, select Auto to enable BIOS support. The choices are Auto, and Disabled. IDE HDD Block Mode Block mode is also called block transfer, multiple commands, or multiple sector read/write. If your IDE hard drive supports block mode (most new drives do), select Enabled for automatic detection of the optional number of block read/write per sector the drive can support. The available choices are Enabled, Disabled. Press to go back to Integrated Peripherals BIOS page when you finish setting up the above items. Onboard device Select this item to setup the onboard device features. When you select this item, the following menu shows: Figure 4-7: BIOS – Onboard Device 48 USB 2.0 Controller Select Enable if your system contains a Universal Serial Bus 2.0 controller and you have USB 2.0 peripherals. USB Keyboard Support Select Enabled if your USB controller is enabled and it needs USB keyboard support in legacy (old) OS operating systems such as DOS. AC97 Audio Selecting Auto will enable the AC’97 audio if it is detected onboard. Onboard Gigabit LAN Enables and disables the onboard LAN modules. SuperI/O Device Select this item to setup the superI/O device features. When you select this item, the following menu shows: Figure 4-8: BIOS – Onboard Device 49 Onboard FDC Controller Select Enabled if your system has a floppy disk controller (FDC) installed on the system board and you wish to use it. If you install an add-in FDC or the system has no floppy drive, select Disabled to this field. Onboard Serial Ports (1, 2) This feature allows you to manually select the I/O address and IRQ for the first and second serial ports. It is recommended that you leave it as Auto so that the BIOS can select the best settings for it. But if you need a particular I/O port or IRQ that's been taken up by this serial port, you can manually select an alternative I/ O port or IRQ for it. You can also disable this serial port if you do not need to use it. Doing so frees up the I/O port and IRQ used by this serial port. Those resources can then be reallocated for other devices to use. UART Mode Select Select an operating mode for the serial port. The choices are: Normal, IrDA, ASKIR. UR2 Duplex Mode In an infrared port mode, this field appears. Full-duplex mode permits simultaneous two-direction transmission. Half-duplex mode permits transmission in one direction only at a time. Select the value required by the IR device connected to the IR port. Onboard Parallel Port This feature allows you to select the I/O address and IRQ for the onboard parallel port. The default I/O address of 378h and IRQ of 7 should work well in most cases. Unless you have a problem with the parallel port, you should leave it at the default settings. The choices: 378/IRQ7, 278/IRQ5, 3BC/IRQ7, and Disabled. Parallel Port Mode Select an operating mode for the onboard parallel (printer) port. There are four options: SPP (Standard Parallel Port), EPP (Enhanced Parallel Port), ECP (Extended Capabilities Port) and ECP+EPP. ECP Mode Use DMA When the on-board parallel port is set to ECP mode, the parallel port can use DMA3 or DMA1. Power On Function Use the button only for power on function. Hot Key Power On Press “Ctrl-F1” for hot key power on. 50 After you have made your selections in the Integrated Peripherals setup, press the key to go back to the main program screen. 4.11 Power Management Setup This option lets you control system power management. The system has various power-saving modes including powering down the hard disk, turning off the video, suspending to RAM, and software power down that allows the system to be automatically resumed by certain events. The power-saving modes can be controlled by timeouts. If the system is inactive for a time, the timeouts begin counting. If the inactivity continues so that the timeout period elapses, the system enters a power- saving mode. If any item in the list of Reload Global Timer Events is enabled, then any activity on that item will reset the timeout counters to zero. If the system is suspended or has been powered down by software, it can be resumed by a wake up call that is generated by incoming traffic to a modem, a LAN card, a PCI card, or a fixed alarm on the system real- time clock. Selecting Power Management Setup on the main program screen displays this menu: Figure 4-9: BIOS – Power Management Setup 51 Power-Supply Type Switch to ATX if it is an ATX power supply type. Auto Power-Failure Resume Choose OFF if auto poewr is resumed. ACPI Function The ACPI standard (Advanced Configuration and Interface power) allows the operating system directly to check the functions of energy saving and the PnP (Plug and Play) functionality. The ACPI functions are normally activated by the BIOS. The choices are: Enabled and Disabled. Video Off Method This determines the manner in which the monitor is blanked. There are three choices: 1. V/H SYNC+Blank: This selection will cause the system to turn off the vertical and horizontal synchronization port and write blanks to the video buffer. 2. Blank Screen: This option only writes blanks to the video buffer. 3. DPMS Support: Select this option if your monitor supports the Display Power Management signaling (DPMS) standard of the Video Electronics Standard to select video power management values. Video Off In Suspend This determines the manner in which the monitor is blanked. The choices: Yes, No. MODEM Use IRQ This determines the IRQ in which the MODEM can use. The choices are 3, 4, 5, 7, 9, 10, 11, and NA Suspend Mode After the selected period of system inactivity, all devices except the CPU shut off. The choices are 1~2 min, 2~3 min,…. Up to 1 hour. HDD Power Down After the selected period of drive inactivity, the hard disk drive powers down while all other devices remain active. Soft-Off by PWR-BTTN This function can turn the system off with the on/off button places the system in a very low-power-usage state, with only enough circuitry receiving power to detect power button activity or Resume by Ring activity. The choices are Delay 4 seconds, and Instant-Off. 52 Wake up by PCI Card When the system enters a Soft-off mode (Standby power exist but system is not working), it will wake up system when specific signals occurred. The BIOS monitors the system for “activity” to determine when to enable power management. If you enable this feature, the computer specifies that any signal noticed on the PCI (Peripheral Component Interconnect) bus channel must make go out from the hibernation state. The choices: Enabled, Disabled. Power On by Ring An input signal on the serial Ring Indicator (RI) line (in other words, an incoming call on the modem) awakens the system from a soft off state. The choices: Enabled, Disabled. Reload Global Timer Events Primary/Secondary IDE 0/1 FDD, COM, LPT Port PCI PIRQ [A-D]# The events are I/O events whose occurrence can prevent the system from entering a power saving mode or can awaken the system from such a mode. In effect, the system remains alert for anything, which occurs to a device, which is configured as Enabled, even when the system is in a power down mode. The choices are Enabled, and Disabled. After you have made your selections in the Power Management setup, press the key to go back to the main program screen. 4.12 PnP/PCI Configurations This section describes configuring the PCI bus system. Peripheral Component Interface, is a system which allows I/O devices to operate at speeds nearing the speed the CPU itself uses when communicating with its own special components. This section covers some very technical items and it is strongly recom- mended that only experienced users should make any changes to the default settings. Selecting PnP/PCI Configurations on the main program screen displays this menu: 53 Figure 4-10: BIOS – PnP/PCI Configurations Reset Configuration Data Normally, you leave this field Disabled, Select Enabled to reset Extended System Configuration Data (ESCD) when you exit Setup if you have installed a new add-on Card and the system reconfiguration has caused such a serious conflict that the operating system can not boot. The choices are Enabled and Disabled. Resources Controlled By The Award Plug and Play BIOS has the capacity to automatically configure all of the boot and Plug and Play compatible devices. However, this capability means absolutely nothing unless you are using a Plug and Play operating system such as going into each of the submenus that follows this field. The choices are Auto (ESCD), Manual. 4.13 PC Health Status When main boards support hardware monitoring, this item lets you monitor the parameters for critical voltages, critical temperatures, and fan speeds. These are the read only items. After you have read the PC Health Status, press the key to go back to the main program screen. 4.14 Load Fail-Safe Defaults This option opens a dialog box that lets you install fail-safe defaults for all appropriate items in the whole setup utility. Press the key and then to install the defaults. Press the key and then to not install the defaults. Use this option if you have changed your system and it does not operate correctly or does not power up. 54 4.15 Load Optimized Defaults This option opens a dialog box that lets you install optimized defaults for all appropriate items in the whole setup utility. Press the key and then to install the defaults. Press the key and then to not install the defaults. The optimized defaults place demands on the system that may be greater than the performance level of the components, such as the CPU and the memory. You can cause fatal errors or instability if you install the optimized defaults when your hardware does not support them. If you only want to install setup defaults for a specific option, select and display that option, and then press the key. 4.16 Set Password The User Password utility sets the password. The main board is shipped with the password disabled. If you want to change the password, you must first enter the current password, then at the prompt enter your new password. The password is case sensitive. You can use up to eight alphanumeric characters. Press after entering the password. At the next prompt, confirm the new password by retyping it and pressing again. To disable the password dialog box appears. A message appears confirming that the password has been disabled. If you have set supervisor and user Password, only the supervisor password allows you to enter the BIOS setup program. Note: If you forget your password, the only way to solve this problem is to discharge the CMOS memory by turning power off and placing a shunt (jumper cap) on jumper JP2 to short pin 2 and pin 3 for five seconds, then putting the shunt back to pin 1 and pin 2 of JP2. 4.17 Save & Exit Setup Selecting this option and pressing will save the new setting information in the CMOS memory and continue with the booting process. 4.18 Exit Without Saving Selecting this option and pressing will exit the Setup utility without recording any new values or changing old ones. This concludes Chapter 4. The next chapter covers drivers installing. 55 Appendix A Watchdog Timer 56 56 The NEX852VL(2) features a watchdog timer that reset the CPU or generates an interrupt if the processor stops operating for any reason. This feature ensures system reliability in industrial standalone or unmanned environments. A.1 Watchdog Timer Working Procedure The Watchdog Timer (WDT) is a special hardware device that monitors the computer system during normal operation. The WDT has a clock circuit that times down from a set number to zero. If a monitored item occurs before the timer reaches zero, the WDT resets and counts down again. If for some reason the monitored item doesn’t occur before the timer reaches zero, the WDT performs an action, such as a diag- nostic operation (rebooting the computer) or generate an NMI. You must enter timer values into the WDT Configuration Register (Write the control value to the Configura- tion Port), and clear (read the Configuration Port).

Write the value to the WDT Configu- ration Port. The following table describes the Control Register bit definition. 7 6 5 4 3 2 1 0 110: Select 127 seconds or m inutes 110: Select 64 seconds or m inutes 101: Select 32 seconds or m inutes 100: Select 16 seconds or m inutes 011: Select 8 seconds or m inutes 010: Select 4 seconds or m inutes 001: Select 2 seconds or m inutes 000: Select 1 seconds or m inutes 1 : Select W DT count m ode by m inute 0 : Select W DT count m ode by second 1 : Enable watch dog tim er 0 : D isable watch dog tim er 1 : NM I is Enable 0 : NM I is D isable 1 : Reset is Enable 0 : Reset is D isable 1 : W DT is Enable 0 : W DT is Disable Table A-2: Control Register Bit Definition A.3 Watchdog Timer Programming Procedure Power on or reset the system The initial value of WDT Control Register (D4~D0) is zero, when power is on or reset the system. The following shows the initial value of WDT (00000000b): Be itVn alu Mea 70 Disable WDT 60 Reset output is disable 50 NMI output is disable 40 WDT Notice output is disable 30 Select WDT count mode by second 20 , 1, 00e 0 Select time-out occurs after 1 second/minut Table A-3: WDT Control Register Initial Value 58 Clear the WDT The WDT counter internal cannot be longer than the preset time, otherwise, the WDT generates a NMI (Non Maskable Interrupt) or sends a reset signal to the system. Note: Before running WDT, clear the WDT to make sure the initial value is zero before enabling the WDT. WDT Control Register (Write to WDT configuration port) Note: This register writes to the WDT configuration port. You can set the WDT Control Register to control the WDT working mode. Follow below instructions to set the initial value of the WDT working mode. 1. Select the WDT time out occurs time Time-out intervals decide by values of bit 2, bit 1, bit 0 in I/O port 2E0h minute or second decide by values of bit 3 in I/O port 2E0h 2. Enable or Disable WDT Notice Output decide by bit 4 value in I/O port 2E0h 3. Enable or Disable NMI Output decide by bit 5 value in I/O port 2E0h 4. Enable or Disable Reset Output decide by bit 6 value in I/O port 2E0h 5. Enable or Disable the WDT decide by bit 7 value in I/O port 2E0h After finishing the above settings, you must output the Control Register’s value to the WDT Configuration Port. Then WDT will start according to the above settings. Note: Build a mechanism in the program to continue to read the WDT Configuration Port for clearing WDT before time out. 59 Appendix B GPI/O Programming 60 60 This appendix provides definitions for the four GPI/O pins in the NEX852VL(2). GPI/O (General Purpose Input/Output) pins are provided for custom system design. The pin programming as input mode (GPI) or output mode (GPO) is depending on the configuration. The pin definitions are shown in the following table: Default Default Pin Default Pin Default GPI/O mode Corresponding GPI/O mode Corresponding No. PowerOn No. PowerOn Pin Pin 11D1 igital Output R2 ead HighD1 igital Input1 High 32D1 igital Output R4 ead HighD1 igital Input2 High 53D1 igital Output R6 ead HighD1 igital Input3 High 74D1 igital Output R8 ead HighD1 igital Input4 High 95V- CC 1D0G- N Table B-1 : J38 - GPI/O Connector Pin Definition Š All digital output have pull-up to +3.3V Š BIOS controls the GPI/O Default Function Š Bit1~3: Reading the bit returns the digital input corresponding pin. Write is ignored. 0 - Corresponding pin level low 1 - Corresponding pin level high Š Bit4~7: The bit corresponds to pin of digital output. Reading the bit returns it’s value that written before. 0 - Corresponding pin driven to low 1 - Corresponding pin released to high (default) 61
