General Information This chapter provides background information for the SBC-456/E Rev.B. Sections include: • Card specifications • Board layout Chapter 1 General Information 1 CHAPTER Introduction The SBC-456/E Rev.B is an all-in-one single board 486 computer with an onboard SM-712 CRT/LCD controller, 10/100 Base-T Ethernet controller, and 16 MB EDO DRAM. It packs all the functions of an industrial computer but still fits in a single, half-size card. This means the SBC-456/E Rev.B is absolutely your best solution for embedded applications. The onboard PCI-bus, flat panel/CRT SVGA controller uses the SM- 712 chipset with up to 2 MB of video memory. This chipset, used with the local PCI-bus, enables 32-bit graphic throughput at up to 33 MHz. It can support various LCD types, including TFT, DSTN, B/W, and EL due to it's excellent performance on display-intensive applications. The onboard Ethernet Realtek RTL 8139C controller supports remote boot ROM functions.The SBC-456/E Rev.B supports the M-Systems DiskOnChip 2000 , DiskOnModule, and Compact FlashCard which are new generation of high performance storage units. Another outstanding feature of the SBC-456/E Rev.B is the inclusion of a high speed, local bus IDE controller, which supports (through ATA PIO) mode 3 and mode 4 hard disks, enabling data transfer rates in excess of 11 MB/second. Up to four IDE devices can be connect- ed, including large hard disks, CD-ROM drives, tape backup drives, or other IDE devices. The built-in, enhanced IDE controller provides a 4-layer, 32-bit, posted write buffer and a 4-layer, 32-bit read- prefetch buffer to boost IDE performance. Onboard features include three high speed RS-232 serial ports, and one RS-232/422/485 serial port with 16C550 UARTs, one bidirectional SPP/EPP/ECP parallel port and a floppy drive controller. In addition to the 486's 16 KB of onchip cache memory, the SBC-456/E Rev.B includes an extra 128 KB of L2 onboard cache memory. If program execution is halted by a program bug or EMI, the board's 2 SBC-456/E Rev. B User Manual watchdog timer can automatically reset the CPU or generate an interrupt. This ensures reliability in unmanned or standalone systems. All configuration display and Ethernet (SBC-456/E Rev. B) is done through software. A single Flash chip holds the system BIOS and the network boot ROM image. This minimizes the number of chips and eases configuration. You can change the display BIOS or install a boot ROM simply by programming the Flash chip. The SBC-456/E Rev. B supports 5 V EDO DRAM. It also provides one 72-pin SIMM (Single In-line Memory Module) socket for its onboard system DRAM. These sockets give you the flexibility to configure your system from 4 MB to 64 MB of DRAM by using the most economical combination of SIMMs. Features Onboard AMD 486DX5-133 CPU (SQFP) SM-712 LCD controller Built-in 2MB SGR`AM memory 10/100Base-T Ethernet Supports DOC PC/104 expansion connector 4 COMs CFD socket supported DOM Module Supported Chapter 1 General Information 3 Specifications General Functions CPU: AMD 486DX5-133 CPU type: Onboard SQFP Bus Interface: ISA bus BIOS: AWARD 128KB FLASH BIOS Chipset: ALi M1487/1489 I/O Chipset : Two ITE IT8661F, fully 16-bit I/O decoded L2 Cache: Onboard 128KB L2 Cache,and could be upgraded to 512KB by factory Memory: Onboard 16M EDO RAM (bank 0) and One 72-pin SIMM sockets support up to 128Mbytes Fast Page or EDO DRAM Enhanced IDE: Supports two IDE devices and Bus Master mode with data transfer rate 16.7 MB/sec (One channel reserved for CFD) FDD interface: Supports two floppy disk drives, 5.25" (360 KB and 1.2 MB) and/or 3.5" (720KB, 1.44MB, and 2.88MB) Parallel port: One bi-directional parallel port which supports SPP, ECP, and EPP modes Serial port: Three RS-232 and one RS-232/422/485 serial ports.

It consists of two metal pins and a small metal clip (often protected by a plastic cover) that slides over the pins to connect them. To close a jumper, connect the pins with the clip. To "open" a jumper, please remove the clip. Sometimes a jumper will have three pins, labeled 1, 2, and 3. In this case you would connect either pins 1 and 2 or 2 and 3. 3 2 1 Open Closed Closed 2-3 The jumper settings are schematically depicted in this manual as follows: 1 2 3 Open Closed Closed 2-3 A pair of needle-nose pliers may be helpful when working with jumpers. If you have any doubts about the best hardware configuration for your applications, contact your local distributor or sales represen- tative before you make any changes. 12 SBC-456/E User Manual Safety precautions Warning! Always completely disconnect the power cord from your chassis whenever you are working on it. Do not make connections while the power is on because sensitive electronic components can be damaged by the sudden rush of power. Only experienced electronics personnel should open the PC chassis. Caution! Always ground yourself to remove any static charge before touching the CPU card. Modern electronic devices are very sensitive to static electric charges. Use a grounding wrist strap at all times. And place all electronic components on a static-dissipative surface or in a static-shielded bag when they are not in the chassis. Chapter 2 Installation 13 Installing DRAM (SIMM) The SBC-456/E Ver. B CPU card provides one 72-pin SIMM (Single In-line Memory Module) socket and supports between 4MB and 64MB. Installing SIMM Note: The module can only fit into a socket one way. 1. Insert the memory module into the socket at a moderate angle. 2. Push the module toward the vertical posts at both ends of the socket until the module is upright and the retaining clips at both ends of the module click into place. When positioned correctly, the pins on top of the vertical posts should correspond to the circular holes on the ends of the module. Removing SIMM If you need to remove a SIMM, follow the procedures below: 1. Supporting the SIMM with a finger, use a pen or a similarly shaped object and press one retaining clip straight down. 2. Repeat for the other side. When released, the retaining clips will push the SIMM up and out of its upright position. 3.

Press enter, the Advanced CMOS Setup screen appears: 38 SBC-456/E Rev. B User Manual Date and Time Configuration The BIOS determines the day of the week from the other date information. This field is for information only. Press the left or right arrow key to move to the desired field (date, month, year). And press the PgUp/- or PgDn/+ key to increment the setting, or type the desired value into the field. 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. And press the PgUp/- or PgDn/+ key to increment the setting, or type the desired value into the field. HARD DISKS The BIOS supports up to four IDE drives. This section does not show information about other IDE devices, such as a CD-ROM drive, or other hard drive types, such as SCSI drives. NOTE: We recommend that you select type AUTO for all drives. The BIOS can automatically detect the specifications and optimal operating mode of almost all IDE hard drives. When you select type AUTO for a hard drive, the BIOS detects its specifications during POST, every time the system boots. If you do not want to select drive type AUTO, other methods of selecting the drive type are available: 1. Match the specifications of your installed IDE hard drive(s) with the preprogrammed values for drive types 1 through 45. 2. Select USER and key values into each drive parameter field. 3. Use the IDE HDD AUTO DECTECTION function in Setup. The following is a brief explanation of drive specifications on next page: Chapter 3 BIOS Setup 39 Type: The BIOS contains a table of pre-defined drive types. Each defined drive type has a specified number of cylinders, number of heads, write precompensation factor, landing zone, and number of sectors. Drives whose specifications do not accommodate any pre-defined type are classified as type USER. ? Size: Disk drive capacity (approximate). Note that this size is usually slightly greater than the size of a formatted disk given by a disk-checking program. ? Cyls: Number of cylinders ? Head: Number of heads ? Precomp: Write precompensation cylinder ? Landz: Landing zone ? Sector: Number of sectors ? Mode: Auto, Chs, Large, or LBA - Auto: The BIOS automatically determines the optimal mode. - Chs: Maximum number of cylinders, heads, and sectors supported are 1024, 16, and 63. - Large: For drives that do not support LBA and have more than 1024 cylinders. - LBA (Logical Block Addressing): During drive accesses, the IDE controller transforms the data address described by sector, head, and cylinder number into a physical block address, significantly improving data transfer rates. For drives with greater than 1024 cylinders. 40 SBC-456/E Rev. B User Manual Drive A Drive B Select the correct specifications for the diskette drive(s) installed in the computer.

You can tell the BIOS to ignore certain errors during POST and continue the boot-up process. These are the selections: ?No errors: POST does not stop for any error. ? All errors: The BIOS detects any non-fatal error, POST stops and prompts you to take corrective action. ? All, But Keyboard: POST does not stop for a keyboard error, but stops for all other errors ? All, But Diskette: POST does not stop for diskette drive errors, but stops for all other errors. ? All, But Disk/Key: POST does not stop for a keyboard or disk error, but stops for all other errors. 42 SBC-456/E Rev. B User Manual BIOS Features Setup By choosing the BIOS FEATURES SETUP option from the INITIAL SETUP SCREEN menu, the screen below is displayed. The displayed configuration is based on the manufacturer's SETUP DEFAULTS settings. Virus Warning When enabled, you receive a warning message if a program (specifically, a virus) attempts to write to the boot sector or the partition table of the hard disk drive. You should then run an anti- virus program. Keep in mind that this feature protects only the boot sector, not the entire hard drive. NOTE: 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 first disable the virus warning. The choices:Disabled or Enabled. Chapter 3 BIOS Setup 43 CPU Internal Cache/External Cache Cache memory is additional memory that is much faster than conventional DRAM (system memory). CPUs from 486-type on up contain internal cache memory, and most, but not all, modern PCs have additional (external) cache memory. When the CPU requests data, the system transfers the requested data from the main DRAM into cache memory, for even faster access by the CPU. The External Cache field may not appear if your system does not have external cache memory. The choices: Enabled or Disabled. Quick Power On Self Test Select Enabled to reduce the amount of time required to run the power-on-self-test (POST). A quick POST skips certain steps. We recommend that you normally disable quick POST. Better to find a problem during POST than lose data during your work. The choices:Disabled or Enabled. Boot Sequence The original IBM PCs loaded the DOS operating system from drive A (floppy disk), so IBM PC-compatible systems are designed to search for an operating system first on drive A, and then on drive C (hard disk). However, the BIOS now offers many boot sequence options. The choices:A,C / C, A / C, CDROM, A / CDROM,C,A / C only. Swap Floppy Drive This field is effective only in systems with two floppy drives. Selecting enabled assigns physical drive B to logical drive A, and physical drive A to logical drive B. The choices:Disabled or Enabled. 44 SBC-456/E Rev. B User Manual Boot Up Floppy Seek When Enabled, the BIOS tests (seeks) floppy drives to determine whether they have 40 or 80 tracks. Only 360-KB floppy drives have 40 tracks; drives with 720 KB, 1.2 MB, and 1.44 MB capacity all have 80 tracks. Because very few modern PCs have 40-track floppy drives, we recommend that you set this field to Disabled to save time. The choices: Enabled or Disabled. Boot Up NumLock Status Toggle between On or Off to control the state of the NumLock key when the system boots. When toggled On, the numeric keypad generates numbers instead of controlling cursor operations. The choices: On or Off. Boot Up System Speed Usually the options are "High" and "Low", where "High" is the normal system speed, and is the default setting. "Low" is for debugging only. The choices: High or Low. Gate A20 Option Gate A20 refers to the way the system addresses memory above 1 MB (extended memory). When set to Fast, the system chipset controls Gate A20. When set to Normal, a pin in the keyboard controller controls Gate A20. Setting Gate A20 to "Fast" can improve system speed, particularly with OS/2 and Windows. The choices: Fast or Normal. Chapter 3 BIOS Setup 45 Memory Parity Check Parity is a measure of the consistency of your system's RAM and memory chips. At boot, the BIOS will both size and test all memory. When a parity error is detected, the BIOS will display a message describing the problem as well as the problem's location, if possi- ble. The boot process will then terminate and you will not be able to continue until the bad chip or SIMM is located and replaced. Disabling the Memory Parity Check allows the system to by-pass the test and allows your system to boot. You then have a choice of continuing to operate your system or attempt to solve the problem. The choices: Enabled or Disabled. Typematic Rate Setting Key strokes repeat at a rate determined by the keyboard controller. When enabled, the typematic rate and typematic delay can be selected. The choices: Disabled orEnabled. 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, 30. Typematic Delay (Msec) When the typematic rate setting is enabled, you can select a typematic delay (the delay before key strokes begin to repeat) of 250, 500, 750 or 1000 milliseconds. Security Option If you have set a password, select whether the password is required every time the system boots, or only when you enter "Setup". The choices: Setup or System. 46 SBC-456/E Rev. B User Manual PS/2 Mouse Function Control This reserves IRQ 12 for a PS/2 mouse if one is found at boot. Normally, the server doesn't have neither mouse nor keyboard. Leaving this on 'Enabled' won't harm. 'Disabled' is safer (IRQs might otherwise be reassigned if someone connects a mouse during tests with a local console). The choices: Enabled or Disabled. PCI/VGA Palette Snoop This item is useful for a few nonstandard VGA graphics boards. Please leave this field at Disabled. The choices: Disabled or Enabled . OS Select For DRAM>64M Select the operating system that is running with greater than 64MB or RAM on the system. The choices: Non-OS2/OS2 Report No FDD For WIN 95 Report no FDD for Win 95 or not. The choices: Yes or No Shadow Software that resides in a read-only memory (ROM) chip on a device is called firmware. The AwardBIOS permits shadowing of firmware such as the system BIOS, video BIOS, and similar operat- ing instructions that come with some expansion peripherals, such as a SCSI adaptor. Shadowing copies firmware from ROM into system RAM, where the CPU can read it through the 16-bit or 32-bit DRAM bus. Firmware not shadowed must be read by the system through the 8- bit X-bus. Shadowing improves the performance of the system BIOS and similar ROM firmware for expansion peripherals, but it also reduces the amount of high memory (640 KB to 1 MB) avail- able for loading device drivers, etc. Chapter 3 BIOS Setup 47 Enable shadowing into each section of memory separately. Many system designers hardwire shadowing of the system BIOS and eliminate a System BIOS Shadow option. Video BIOS shadows into memory area C8000-DFFFF. The remain- ing areas shown on the BIOS Features Setup screen may be occupied by other expansion card firmware. If an expansion peripheral in your system contains ROM-based firmware, you need to know the address range the ROM occupies to shadow it into the correct area of RAM. 48 SBC-456/E Rev. B User Manual Chipset Features Setup By choosing the CHIPSET FEATURES SETUP option from the INITIAL SETUP SCREEN menu, the screen below is displayed. Auto Configuration Auto Configuration selects predetermined optimal values of chipset parameters. When "Disabled", chipset parameters revert to setup information stored in CMOS. Many fields in this screen are not available when Auto Configuration is "Enabled". The choices: Enabled or Disable. Hidden Refresh When "Disabled", DRAM is refreshed by IBM AT methodology, using a CPU cycles for each refresh. When hidden refresh is "Enabled", the DRAM controller seeks the most opportune moment for a refresh, regardless of CPU cycles, with least disrup- tion of system activity and least performance penalty. Hidden refresh is faster and more efficient, and it also allows the CPU to maintain the status of the DRAM even if the system goes into a power management "suspend" mode. The choices: Disabled or Enabled. Chapter 3 BIOS Setup 49 Memory Hole (15M-16M) You can reserve this area of system memory for ISA adapter ROM. When this area is reserved, it cannot be cached. The user informa- tion of peripherals that need to use this area of system memory usually discusses their memory requirements. The choices: Disabled or Enabled. ISA/IO Recovery The CPU and local bus are much faster than industry standard architecture (ISA) input/output (I/O) bus. Select "Enabled" to allow additional time for I/O devices to respond to the system. Otherwise, data could be lost. If all your I/O devices are capable of fast I/O, selecting "Disabled" can speed up processing. The choices: Enabled or Disabled. Fast-Back-to-Back When Enabled, consecutive write cycles targeted to the same slave become fast back-to-back on the PCI bus. The choices: Enabled or Disabled. 50 SBC-456/E Rev. B User Manual Power Management Setup By choosing the POWER MANAGEMENT option from the INITIAL SETUP SCREEN menu, the screen below is displayed. Power Management This category allows you to select the type ( or degree ) of power saving and is directly related to the following modes: 1. Doze Mode 2. Standby Mode 3. Suspend Mode Max Saving (Maximum power savings. Only Available for SL CPU) 1. Doze Mode--10 Sec 2. Standby Mode--10 Sec 3. Suspend Mode--10 Sec Min Saving (Minimum power savings) 1. Doze Mode--1 Hour 2. Standby Mode--1 Hour 3. Suspend Mode--1 Hour User Define You can set the Doze Mode, Standby Mode, and Suspend Mode individaully. Chapter 3 BIOS Setup 51 PM Control by APM If Advanced Power Management (APM) is installed on your system, selecting Yes gives better power savings. The choices: Yes or No. Vedio Off Option Selects the power-saving mode during the monitor goes blank: Always On Monitor remains on during power-saving modes. Suspend ->Off Monitor blanked when system enters Suspend mode. Susp, Stby -> Off Monitor blanked when system enters either Suspend or Standby mode. All Modes -> Off Monitor blanked when system enters any power saving mode. Video Off Method This determines the manner in which the monitor is blanked. This selection will cause the system to turn off V/H SYNC + Blank the vertical and horizontal synchronization ports and write blanks to the video buffer Blank Screen This option only writes blanks to the video buffer DPMS Initial display power management signaling MODEM Use IRQ Name the interrupt request (IRQ) line assigned to the modem (if any) on your system. Activity of the selected IRQ always awakens the system. The choices: 3,4,5,7,9,10,11,or NA. 52 SBC-456/E Rev. B User Manual HDD Power Down After the selected period of drive inactivity, the hard disk drive powers down while all other devices remain active. The choices: 1~15 min. Doze, Standby, Suspend Mode Please check the Power Management item in Page 49. PM Events You may disable activity monitoring of some common I/O events and interrupt requests so they do not wake up the system. The default wake-up event is keyboard activity. When On (or named, in the case of LPT & COM), any activity from one of the listed system peripheral devices or IRQs wakes up the system. A power-management (PM) event awakens the system from, or resets activity timers for Suspend mode. You can disable monitor- ing of common interrupt requests so they do not generate PM events. Chapter 3 BIOS Setup 53 PCI Configurations PnP BIOS Auto-Config The Award Plug and Play BIOS can automatically configure Plug and Play-compatible devices. If you select "Enabled", the Avail- able IRQ fields disappear, because the BIOS automatically handles their configuration. The choices: Enabled or Disabled.. Slot 1/2/3/4 Using INT# Some PCI devices use interrupts to signal that they need to use the PCI bus. Other devices, most graphics adapters, do not need interrupt service at all. Each PCI slot can activate up to four interrupts, INT# A, INT# B, INT# C and INT# D. By default, a PCI slot is allowed INT# A. Assigning INT# B has no meaning unless the device in the slot requires two interrupt services rather than just one. Likewise, using INT# C can only mean the device requires three interrupts; and using INT# D, four interrupts. Selecting the default, AUTO, allows the PCI controller to automati- cally allocate the interrupts. The choices: Auto, A, B,C or D. 54 SBC-456/E Rev. B User Manual 1st/2nd/3rd/4th Available IRQ If you select "Disabled" in the PnP BIOS Auto-Config item, the Available IRQ fields will appear. And when an installed PCI device requires interrupt service, you may manually select an unused interrupt line for PCI IRQs. NA indicates the interrupt is assigned to an ISA bus device and is not available to any PCI slot. The choices: 5,9,10,11,12,14,15, or NA.. PCI IRQ Actived By Leave the IRQ trigger set at Level unless the PCI device assigned to the interrupt specifies Edge-triggered interrupts. The choices: Level or Edge. PCI IDE 2nd Channel Since your chipset supports a second IDE channel, you can use this selection to enable or disable the second channel. The second channel may connect to a CD-ROM. The choices: Enabled or Disabled. PCI IDE IRQ MAP To This field lets you select PCI IDE IRQ mapping or PC AT (ISA) interrupts. If your system does not have one or two PCI IDE connectors on the system board, select values according to the type of IDE interface(s) installed in your system (PCI or ISA). Standard ISA interrupts for IDE channels are IRQ14 for primary and IRQ15 for secondary. The choices: PCI-Auto, ISA, PCI-SLOT1, PCI-SLOT2, PCI- SLOT3, PCI-SLOT4. Chapter 3 BIOS Setup 55 Primary/Secondary IDE INT# If you select "ISA" in the "PCI IDE IRQ Map To" item, this field won't appear. By default, a PCI connection is assigned INT# A. Assigning INT# B has no meaning unless the peripheral device requires two interrupt services rather than just one. Because the PCI IDE interface in the chipset has two channels, it requires two interrupt services. The primary and secondary IDE INT# fields default to values appropriate for two PCI IDE channels, with the primary PCI IDE channel having a lower interrupt than the second- ary. The choices: A, B,C or D. CPU To PCI Write Buffer When this item is enabled, the CPU can write up to four words of data to the PCI write buffer before the CPU must wait for the PCI bus cycles to finish. When "Disabled", the CPU must wait after each write cycle until the PCI bus signals that it is ready to receive more data. The choices: Enabled or Disabled. CPU To PCI Byte Merge Byte merging permits merging of the data in consecutive CPU-to- PCI byte/word writes with the same word address, into the same posted write buffer location. The merged collection of bytes is then sent over the PCI Bus as a single dword. The choices: Enabled or Disabled. PCI To DRAM Buffer Your system supports buffered writes from the PCI bus to DRAM for greater efficiency. The choices: Enabled or Disabled. 56 SBC-456/E Rev. B User Manual Load BIOS Defaults/Load Setup Defaults LOAD BIOS DEFAULTS loads the default system values directly from ROM. The BIOS DEFAULTS provides the most stable settings, though they do not provide optimal performance. LOAD SETUP DEFAULTS, on the other hand, provides for maximum system performance. If the stored record created by the setup utility becomes corrupted (and therefore unusable), BIOS defaults will load automatically when you turn the SBC-456/E Rev. B on. Chapter 3 BIOS Setup 57 Integrated Peripherals By choosing the INTEGRATD PERIPHERALS option from the initial SETUP SCREEN menu, the screen below is displayed. On-Chip Local Bus IDE The chipset contains an enhanced IDE interface with two IDE channels. Because each channel supports two IDE devices, the system supports a total of four IDE devices. If the board has one or two IDE connectors, this option should be Enabled. If you install an add-in IDE interface, please disable one or both on-chip IDE channels. The choices: Enabled or Disabled. IDE Buffer for DOS & Win Select "Enabled" to increase throughput to and from IDE devices by using the on-chip read-ahead and posted-write IDE buffers. Note that use of the buffers may cause some slow IDE devices to be even slower. When in doubt, experiment with this setting for optimal performance and data integrity. The choices: Enabled or Disabled. 58 SBC-456/E Rev. B User Manual The 2nd Channel IDE This option enables the second channel IDE on the board. The choices: Enabled or 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 optimal number of block read/writes per sector the drive can support. The choices: Enabled or Disabled. IDE Primary/Secondary Master/Slave PIO The four IDE PIO (Programmed Input/Output) fields let you set a PIO mode (0-4) 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 will automati- cally determine the best mode for each device. The choices: Auto, Mode0, Mode1, Mode2, Mode3, or Mode4. Onboard FDC Controller Select Enabled if your system has a floppy disk controller (FDC) installed on the board and you wish to use it. If you install an add- in FDC or the system has no floppy drive, please select Disabled in this field. The choices: Enabled or Disabled. Onboard Serial Port 1/2 Select a logical COM port name and matching address for the first and second serial ports. Select an address and corresponding interrupt for the first and second serial ports.

B User Manual 4 Drivers Installtion This SBC-456/E Rev. B is equipped with a VGA and LAN interface. This chapter provides instructions for installing the software drivers on these peripherals. Chapter 4 Drivers Installation 67 CHAPTER Software Drivers This chapter describes the operation and installation of the display drivers supplied on the Supporting CD-ROM shipped with your product. The onboard VGA adapter is based on the CHIPS VGA Flat Panel/CRT controller and is fully IBM VGA compatible. This controller offers a large set of extended functions and higher resolutions. If you intend to use your VGA adapter in standard VGA modes only, you do not need to install any of these drivers. Since your VGA adapter is fully compat- ible, it does not require any special drivers to operate in standard modes. The purpose of the enclosed software drivers is to take advantage of the extended features of the CHIPS VGA Flat Panel/CRT controller. Hardware Configuration Some of the high-resolution drivers provided in this package will work only in certain system configurations. If a driver does not display correctly, please follow these steps: 1. Change the display controller to CRT-only mode, rather than flat panel or simultaneous display mode. Some high-resolution drivers will display correctly only in CRT mode. 2. If a high-resolution mode is not supported in your system, try to adopt a lower-resolution mode. For example, 1024 x 768 mode will not work in some systems, but 800 x 600 mode is supported in most cases. 68 SBC-456/E Rev. B User Manual Necessary to Know The instructions in this manual assume that you understand elementary concepts of MS-DOS and the IBM Personal Computer.

B User Manual A Watchdog Timer Demo Program The following demo program illustrates the programming steps required to enable, set, and disable the watchdog timer. APPENDIX Programming the Watchdog Timer How to Program the Watchdog Timer 1. To set the time-out interval of watchdog timer: -- output the desired value to port 0x443. Since the data is of 1 byte, the maximum value will be 255. In our design, 1 ~ 127 will denote 1sec ~ 127sec, though 129 ~ 255 will denote lmin ~ 127min. e.g. outportb(0x443, 30); // set interval to 30 seconds outportb(0x443, 0x85); // set interval to 5 minutes 2. To set the time-out event: -- output data to prot 0x444, • 0: reset system • 1, 2, 3: IRQ 10, 15, 11 respectively • 4: NMI e.g. outportb(0x444, 0); // set time-out event to reset-system 3. To disable watchdog timer: -- output any value to port 0x80, e.g. outportb(0x80, data); // disable watchdog timer 4. To ebable or refresh watchdog timer(the watchdog timer will return to its initial value, then count down): -- access the I/O port 0x443, e.g. outportb(0x80, 0); // disable watchdog timer inportb(0x443); // refresh watchdog timer * Note: If you want to refresh the watchdog timer, you have to disable it first.
