prepare it for installation into your system. Sections include: • Card specifications • Board layout • Safety precautions • Jumper settings CHAPTER Introduction The SBC-775 industrial grade CPU card uses Intel's highly ® acclaimed Pentium II processor and Intel 440LX PCI chipset. The card works with standard ISA or PCI/ISA-bus passive backplanes. The CPU provides 512 KB on-chip L2 cache, eliminating the need for external SRAM chips. It has two PCI EIDE interfaces (for up to four devices), and an FDD interface (for up to two devices). Other features include two RS-232 serial ports (16C550 UARTs with 16-byte FIFO or compatible), one enhanced parallel port (supports EPP/ECP), and support two USB (Universal Serial Bus) ports. The PCI BUS Master IDE controller supports Ultra DMA/33 operation. This provides data transfer rates of over 33 MB/sec, and allows drive capacities up to 8.4 GB. System BIOS supports boot-up from an IDE CD-ROM. A backup of CMOS data is stored in the Flash memory, which protects data even after a battery failure. Also included is a 63-level watchdog timer, which resets the CPU or generates an interrupt if a program cannot be executed normally. This enables reliable operation in unattended environments. 2 SBC-775 User’s Manual Features • Intel slot 1 architecture ® • Pentium II processor up to 333 MHz • Intel 82440LX PCIset • Three DIMM sockets for SDRAM up to 384 MB; supports ECC • Award Flash BIOS • On-board ATX power control connector to meet ACPI requirements • Two enhanced IDE ports, supporting Ultra DMA/33, PIO Mode 4 and DMA Mode 2 • Two USB ports • Two serial ports • One bidirectional parallel port, supports ECP/EPP/SPP • One floppy port and one keyboard/mouse port • PCI V2.1 compliant • PICMG 2.0 compliant • Additional metal bracket to provide board stability with Pentium II processor • CMOS backup battery life of 7 years ® • Supports M-Systems DiskOnChip 2000 Flash disk • On-board security system for monitoring CPU fan and voltage Chapter 1 Hardware Configuration 3 Specifications System ® • CPU: Intel Pentium II up to 333 MHz • BIOS: Award Flash BIOS • Green function: Supports power management operation via BIOS.

Always completely disconnect the power cord from your chassis whenever you work with the hardware. Do not make connections while the power is on. Sensitive electronic components can be damaged by sudden power surges. 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. As a safety precaution, use a grounding wrist strap at all times. Place all electronic components in a static-dissipative surface or static-shielded bag when they are not in the chassis. Chapter 1 Hardware Configuration 11 Jumper Settings This section provides instructions on how to configure your card by setting jumpers. It also includes the card's default settings and your options for each jumper. How to set jumpers You configure your card to match the needs of your application by setting jumpers. A jumper is the simplest kind of electric switch. 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 you connect the pins with the clip. To “open” a jumper you remove the clip. Sometimes a jumper consists of a set of three pins, labeled 1, 2 and 3. In this case you connect either pins 1 and 2, or 2 and 3. A pair of needle-nose pliers may be useful when setting jumpers. CPU core frequency (J5) You must configure your SBC-775 CPU card to the frequency of your ® Intel Pentium II processor by setting jumper J5. The SBC-775 is equipped to use Pentium processors with speeds of 233, 266, 300 and 333 MHz. Configure your SBC-775 as follows: Table 1-3: CPU core frequency (J5) A B C D AB C D 233 MHz open closed closed closed AB C D 266 MHz open open open open AB C D 300 MHz* open closed open open AB C D 333 MHz open open closed open * default 12 SBC-775 User’s Manual CMOS clear (J6) The SBC-775 CPU card contains a jumper that can erase CMOS data and reset the system BIOS information. Normally this jumper should be set with pins 1-2 closed. If you want to reset the CMOS data, set J6 to 2-3 closed for just a few seconds, and then move the jumper back to 1-2 closed. This procedure will reset the CMOS to its default setting. Table 1-4: CMOS clear jumper settings (J6) Function Jumper setting 1 Keep CMOS data 1-2 closed* 1 Clear CMOS data 2-3 closed * default Watchdog timer output (J8) The SBC-775 contains a watchdog timer that will reset the CPU or send a signal to IRQ11 in the event the CPU stops processing. This feature means the SBC-775 will recover from a software failure or an EMI problem. The J8 jumper settings control the outcome of what the computer will do in the event the watchdog timer is tripped. Table 1-5: Watchdog timer output (J8) Function Jumper setting 1 IRQ11 1-2 closed 1 Reset 2-3 closed* * default Chapter 1 Hardware Configuration 13 CPU bus clock select (J11) ® The CPU clock varies according to the Pentium II processor's CPU bus clock. There are two settings for the CPU clock, 66.6 MHz and 75 MHz. Table 1-6: CPU clock select jumper settings (J11) Function Jumper setting 1 66.6 MHz 1-2 closed* 1 75 MHz 2-3 closed * default Note: 75 MHz exceeds the product's specifications. 14 SBC-775 User’s Manual ® DiskOnChip 2000 Flash disk address select (J12) The SBC-775 includes a 32-pin socket for M-System's DiskOnChip 2000 Flash disk module. This revolutionary solid state disk enables critical system information to be stored within an on-board Flash disk for virtually instantaneous data access. You must specify the memory address you wish to use for your DiskOnChip 2000 Flash disk module by setting jumper (J12). Available settings are as follows: ® Table 1-7: DiskOnChip 2000 Flash disk memory address jumper settings (J12) Address 1-2 3-4 5-6 12 C800 closed closed closed 5 6 12 CC00 closed closed open 5 6 12 D000 closed open closed 5 6 12 D400 closed open open 5 6 12 D800 open closed closed 5 6 12 DC00 open closed open 5 6 12 E000 open open closed 5 6 12 Disabled* open open open 5 6 * default Chapter 1 Hardware Configuration 15 System Memory The top-left edge of the SBC-775 contains three sockets for 168-pin dual inline memory modules (DIMMs). All three sockets use 3.3 V unbuffered synchronous DRAMs (SDRAM). DIMMs are available in capacities of 16, 32, 64 or 128 MB. The sockets can be filled in any combination with DIMMs of any size, giving your SBC-775 single board computer between 16 and 384 MB of memory. Use the follow- ing table to calculate the total DRAM memory within your computer: Table 1-8: DIMM module allocation table Socket number 168-pin DIMM memory 1 (8, 16, 32, 64 or 128 MB) x 1 2 (8, 16, 32, 64 or 128 MB) x 1 3 (8, 16, 32, 64 or 128 MB) x 1 Sample calculation: DIMM memory capacity Suppose you install a 128 MB DIMM into your SBC-775's socket 1, a 32 MB DIMM into socket 2, and you leave socket 3 empty. Your total system memory is calculated as follows, and is 160 MB: Table 1-9: DIMM memory capacity sample calculation Socket number 168-pin DIMM memory Total memory 1 128 MB x 1 128 MB 2 32 MB x 1 32 MB 3- x 1 0 MB Total memory 160 MB 16 SBC-775 User’s Manual Supplementary information about DIMMs Your SBC-775 can accept four kinds of memory chips: EDO (with or without parity), and SDRAM (with or without parity). Also: • SDRAM chips are usually thinner and have higher pin density than EDO chips. • The BIOS displays EDO and SDRAM memory on the boot-up screen. • Chips with 9 chips/side support parity; chips with 8 chips/side do not support parity. • Single-sided modules are typically 16 or 64 MB; double-sided modules are usually 8, 32 or 128 MB. Note: The SBC-775 accepts EDOs both with and without parity, but this is not recommended. Chapter 1 Hardware Configuration 17 Memory Installation Procedures To install DIMMs, first make sure the two handles of the DIMM socket are in the "open" position. i.e. The handles remain outward. Slowly slide the DIMM module along the plastic guides on both ends of the socket. Then press the DIMM module right down into the socket, until you hear a click. This is when the two handles have automatically locked the memory module into the correct position of the DIMM socket. (See Figure 1-3.) To take away the memory module, just push both handles outward, and the memory module will be ejected by the mechanism in the socket. Figure 1-3: DIMM installation 18 SBC-775 User’s Manual Cache Memory ® Since the second level cache has been embedded into the Pentium II CPU, you do not have to take care of either SRAM chips or SRAM modules. The built-in second level cache in the Pentium II yields much higher performance than the external cache memories. The cache size in the Pentium II CPU is either 256 KB or 512 KB. Normally, for workstation and server application, the 256 KB version is enough. However, if your system is for heavy duty applications, the 512 KB version will help a lot. Specifically for our Pentium II based SBC, the Pentium II has another version that provides much better data security if combined with the DRAM ECC. Check with your vendor for various Pentium II models. Chapter 1 Hardware Configuration 19 Mounting the CPU and Cooling Modules ® The Pentium II is a module-type CPU which runs at high speeds, for example 233 ~ 333 MHz, so the cooling mechanism becomes critical for system reliability. There are two types of cooling methods: one with a cooling fan attached to the heat sink of the Pentium II module, the other with a huge heat sink without any cooling fan attached. Both cooling methods for the Pentium II require a "retention module" to firmly fix the Pentium II CPU to slot 1. The following Figures 1-4 through 1-6 illustrate the steps involved in mounting the retention module and installing the CPU and cooling modules. Step 1 Figure 1-4: Mounting CPU and cooling modules - Step 1 20 SBC-775 User’s Manual Figure 1-5: Mounting CPU and cooling modules - Step 2 Step 2 Step 3 Figure 1-6: Mounting CPU and cooling modules - Step 3 Chapter 1 Hardware Configuration 21 On-board Support Bracket The SBC-775 also includes an on-board metal bracket to provide balanced support for the Pentium II processor cartridge. Figure 1-7: On-board support bracket 22 SBC-775 User’s Manual 2 Connecting Peripherals This chapter tells how to connect peripherals, switches and indicators to the SB-775 board. You can access most of the connectors from the top of the board while it is installed in the chassis. If you have a number of cards installed, or your chassis is very tight, you may need to partially remove the card to make all the connections. CHAPTER Primary (CN6) and Secondary (CN7) IDE Connectors You can attach up to four IDE (Integrated Device Electronics) drives to the SBC-775’s internal controller. The primary (CN6) and secondary (CN7) connectors can each accommodate two drives. Wire number 1 on the cable is red or blue and the other wires are gray. Connect one end to connector CN6 or CN7 on the CPU card. Make sure that the red/blue wire corresponds to pin 1 on the connec- tor (in the upper right hand corner). See Chapter 1 for help finding the connector. Unlike floppy drives, IDE hard drives can connect in either position on the cable. If you install two drives to a single connector, you will need to set one as the master and one as the slave. You do this by setting the jumpers on the drives. If you use just one drive per connector, you should set each drive as the master. See the docu- mentation that came with your drive for more information. Connect the first hard drive to the other end of the cable. Wire 1 on the cable should also connect to pin 1 on the hard drive connector, which is labeled on the drive circuit board. Check the documentation that came with the drive for more information. Connect the second hard drive to the remaining connector (CN7 or CN6), in the same way as described above. Floppy Drive Connector (CN13) You can attach up to two floppy disk drives to the SBC-775's on-board controller. You can use any combination of 5.25" (360 KB/1.2 MB) and/or 3.5" (720 KB/1.44/2.88 MB) drives. The card comes with a 34-pin daisy-chain drive connector cable. On one end of the cable is a 34-pin flat-cable connector. On the other end are two sets of floppy disk drive connectors. Each set consists of a 34-pin flat-cable connector (usually used for 3.5" drives) and a printed circuit-board connector (usually used for 5.25" drives). You can use only one connector in each set. The set on the end (after the twist in the cable) connects to the A: floppy drive. The set in the middle connects to the B: floppy drive. 24 SBC-775 User’s Manual Parallel Port Connector (CN8) The parallel port is normally used to connect the CPU card to a printer. The SBC-775 includes an on-board parallel port, accessed through a 26-pin flat-cable connector, CN8. The card comes with an adapter cable which lets you use a traditional DB-25 connector. The cable has a 26-pin connector on one end and a DB-25 connector on the other, mounted on a retaining bracket. The bracket installs at the end of an empty slot in your chassis, giving you access to the connector. The parallel port is designated as LPT1 and can be disabled or changed to LPT2 or LPT3 in the system BIOS setup. To install the bracket, find an empty slot in your chassis. Unscrew the plate that covers the end of the slot. Screw in the bracket in place of the plate. Next, attach the flat-cable connector to CN8 on the CPU card. Wire 1 of the cable is red or blue, and the other wires are gray. Make sure that wire 1 corresponds to pin 1 of CN8. Pin 1 is on the upper right side of CN8. Keyboard & PS/2 Mouse Connector (CN12) The SBC-775 board provides a keyboard connector. A 6-pin mini-DIN connector (CN12) on the card mounting bracket supports single-board computer applications. The card comes with an adapter to convert from the 6-pin mini-DIN connector to a standard keyboard DIN connector and to a PS/2 mouse connector. Chapter 2 Connecting Peripherals 25 Serial Ports (CN9: COM1; CN10: COM2) The SBC-775 offers two serial ports, CN9 as COM1 and CN10 as COM2. These ports can connect to serial devices (such as a mouse, printers, and so on) or to a communication network. Table 2-1: Serial port connections (COM1, COM2) Connector Ports Address Interrupt CN9 COM1 3F8*, 3E8 IRQ4 CN10 COM2 2F8*, 2E8 IRQ3 * default settings The IRQ and address ranges for both ports are fixed. However, if you want to disable the port or change these parameters later, you can do this in the system BIOS setup. Different devices implement the RS-232 standard in different ways. If you are having problems with a serial device, be sure to check the pin assignments for the connector. 26 SBC-775 User’s Manual Front Panel Connectors (CN2, CN3, CN4, J1 and J2) There are several external switches to monitor and control the SBC- 775. Keyboard lock and power on LED (CN2) CN2 is a 5-pin connector for the keyboard lock and power on LED connection. Refer to Appendix B.12 for detailed information on the pin assignments. If a PS/2 power supply is used, the system's power LED status will be one of the following: PS/2 Power Mode LED Status System On O n System Suspend Flashes eight times/sec. System Off O f f If an ATX power supply is used, refer to Section 2.7.2. External speaker (CN3) CN3 is a 4-pin connector for an extenal speaker connection. If there is no external speaker, the SBC-775 provides an on-board buzzer as an alternative. To enable the buzzer, set pins 3-4 as closed. IDE LED (CN4) You can connect an LED to connector CN4 to indicate when the HDD is active. ATX soft power switch (J1) If your computer case is equipped with an ATX power supply, you should connect the power on/off button on your computer case to J1. This connection enables you to turn your computer on and off. Reset (J2) Many computer cases offer the convenience of a reset button. Connect the wire from the reset button to J2. Chapter 2 Connecting Peripherals 27 ATX Power Control Connectors (J7 and J1) ATX feature connector (J7) and soft power switch connector (J1) The SBC-775 can support an advanced soft power switch function if an ATX power supply is used. To enable the soft power switch function: 1. Take the specially designed ATX-to-PS/2 power cable out of the SBC-775's accessory bag. 2. Connect the 3-pin plug of the cable to J7 (ATX feature connec- tor). 3. Connect the power on/off button to J1. (A momentary type of button should be used.) Warnings: 1. Make sure that you unplug your power supply when adding or removing expansion cards or other system components. Failure to do so may cause severe damage to both your CPU card and expansion cards. 2. ATX power supplies may power on if certain motherboard components or connections are touched by metallic objects. Important: Be sure that the ATX power supply can take at least a 10 mA load on the 5 V standby lead (5VSB). If not, you may have difficulty powering on your system. 28 SBC-775 User’s Manual Controlling the soft power switch It is easy to control the ATX soft power switch. Pushing the button once will switch the system between the "On" and "Suspend" power modes. Pushing the button for more than 4 seconds while in the "On" mode will turn the system off. Users can also identify the current power mode through the system's power LED, as indicated below: ATX Power Mode LED Status System On On System Suspend Flashes eight times/sec. System Off Flashes once/sec. USB Connector (CN11) The SBC-775 CPU card provides two USB (Universal Serial Bus) interfaces, which give complete plug and play, hot attach/detach for up to 127 external devices.The USB interfaces comply with USB Specification Rev. 1.0, and are fuse-protected. The USB interfaces are accessed through a 10-pin flat-cable connector, CN11. The adapter cable has a 10-pin connector on one end and a USB connector on the bracket. The USB interfaces can be disabled in the system BIOS setup. Chapter 2 Connecting Peripherals 29 IR Connector (CN1) This connector supports the optional wireless infrared transmitting and receiving module. This module mounts on the system case. You must configure the setting through the BIOS setup. External Keyboard Connector (J10) In addition the the PS/2 mouse/keyboard connector on the SBC-775's rear plate, there is also an extra on-board external keyboard connec- tor. This gives system integrators greater flexibility in designing their systems. External Suspend Switch Lead (SMI) (J3) This allows the user to manually place the system into a suspend mode or "Green" mode when the system is not in use. System activity is decreased to save electricity and prolong the life of certain components. The 2-pin connector connects to the case-mounted suspend switch. If you do not have a switch for the connector, you may use the "turbo switch", because it does not have any other function. SMI is activated when it detects a "short to open" moment. Therefore, leaving it shorted will not cause any problems. It may require one or two pushes depending on the position of the switch. Wake-up can be controlled by settings in the BIOS, but the keyboard will always allow wake-up. (The SMI lead cannot wake up the sys- tem.) If you want to use the SMI connector, the "Suspend" switch in the Power Management Setup of the BIOS software should be on the default setting "Enable". 30 SBC-775 User’s Manual 3 Award BIOS Setup This chapter describes how to set the card’s BIOS configuration data. CHAPTER Introduction Award’s BIOS ROM has a built-in setup program that allows users to modify the basic system configuration. This type of information is stored in battery-backed RAM so that it retains the setup information when the power is turned off. Entering Setup Turn on the computer and press immediately, to allow you to enter the setup. Standard CMOS Setup Choose the “STANDARD CMOS SETUP” option from the "INITIAL SETUP SCREEN" menu, and the screen below will be displayed. This standard setup menu allows users to configure system components such as date, time, hard disk drive, floppy drive, display, and memory. Figure 3-1: CMOS setup screen 32 SBC-775 User’s Manual BIOS Features Setup The “BIOS FEATURES SETUP” screen appears when choosing the "BIOS FEATURES SETUP" item from the "CMOS SETUP UTILITY" menu. It allows users to configure the SBC-775 according to their particular requirements. Below are some major items that are provided in the BIOS FEATURES SETUP screen: Figure 3-2: BIOS features setup screen Virus Warning During and after the system boots up, any attempt to write to the boot sector or partition table of the hard disk drive will halt the system. In this case, a warning message will be displayed. You can run the anti-virus program to locate the problem. If Virus Warning is disabled, no warning message will appear if anything attempts to access the boot sector or hard disk partition. Chapter 3 Award BIOS Setup 33 Quick Power On Self Test This option speeds up the Power-On Self Test (POST) conducted as soon as the computer is turned on. When enabled, BIOS shortens or skips some of the items during the test. When disabled, the computer conducts normal POST procedures. Boot Sequence This function determines the sequence in which the computer will search the drives for the disk operating system (i.e. DOS). The BIOS provides the folllowing boot sequences: A,C, SCSI C,A. SCSI (Default) C, CDROM, A CDROM, C, A D, A, SCSI E, A, SCSI F, A, SCSI SCSI, A, C SCSI, C, A C only LS120, C Boot Up Floppy Seek During POST, BIOS will determine if the floppy disk drive installed is 40 or 80 tracks. A 360 KB type drive is 40 tracks; while 720 KB, 1.2 MB, and 1.44 MB type drives are all 80 tracks. Enabled BIOS searches the floppy drive to determine if it is 40 or 80 tracks. Note that BIOS cannot differentiate 720 KB, 1.2 MB, and 1.44 MB type drives as they are all 80 tracks. Disabled BIOS will not search for the floppy drive type by track number. Note that there will not be any warning message if the drive installed is 360 KB. 34 SBC-775 User’s Manual Boot Up NumLock Status The default is “On”. On Keypad boots up to number keys. Off Keypad boots up to arrow keys. Boot Up System Speed High Sets the speed to high. Low Sets the speed to low. IDE HDD Block Mode Enabled Enable IDE HDD Block Mode. BIOS will detect the block size of the HDD and send a block command automatically. Disabled Disable IDE HDD Block Mode. Gate A20 Option Normal The A20 signal is controlled by the keyboard controller or chipset hardware. Fast (Default) The A20 signal is controlled by Port 92 or the chipset specific method. Typematic Rate Setting The typematic rate determines the characters per second accepted by the computer. The Typematic Rate setting enables or disables the typematic rate. Typematic Rate (Chars/Sec) BIOS accepts the following input values (characters/second) for typematic rate: 6, 8, 10, 12, 15, 20, 24, 30. Chapter 3 Award BIOS Setup 35 Typematic Delay (msec) Typematic delay is the time interval between the appearance of the first and second characters, when holding down a key. The input values for this category are: 250, 500, 750, 1000 (msec). Security Option This setting determines whether the system will boot up if the password is denied. Access to Setup is, however, always limited. 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 the prompt. Note: To disable security, select "PASSWORD SETTING" in the main menu. At this point, you will be asked to enter a password. Simply press to disable security. When security is disabled, the system will boot, and you can enter Setup freely. OS Select for DRAM > 64 MB This setting is under the OS/2 system. Video BIOS Shadow This determines whether video BIOS will be copied to RAM, which is optional according to the chipset design. When enabled, Video BIOS Shadow increases the video speed. C8000-CBFFF Shadow / DC000-DFFFF Shadow These determine whether optional ROM will be copied to RAM in blocks of 16 KB. Enabled Optional shadow is enabled. Disabled Optional shadow is disabled. 36 SBC-775 User’s Manual CHIPSET Features Setup By choosing the “CHIPSET FEATURES SETUP” option from the INITIAL SETUP SCREEN menu, the screen below will be displayed. This sample screen contains the manufacturer’s default values for the SBC-775. Figure 3-3: CHIPSET features setup screen Note: If you enable the IDE HDD block mode, the enhanced IDE driver will be enabled. Chapter 3 Award BIOS Setup 37 Power Management Setup The power management setup controls the CPU card's “Green” features. The following screen shows the manufacturer’s defaults. Figure 3-4: Power management setup screen Power Management This option allows you to determine if the values in power management are disabled, user-defined, or predefined. HDD Power Management You can choose to turn the HDD off after one of the time intervals listed, or when the system is in Suspend mode. If the HDD is in a power saving mode, any access to it will wake it up. Note: The HDD will not power down if the Power Management option is disabled. 38 SBC-775 User’s Manual IRQ Activity IRQ can be set independently. Activity on any enabled IRQ will wake up the system. PCI Configuration Setup Figure 3-5: PCI configuration screen Load BIOS Defaults “LOAD BIOS DEFAULTS” indicates the most appropriate values for the system parameters for minimum performance. These default values are loaded automatically if the stored record created by the setup program becomes corrupted (and therefore unusable). Load Setup Defaults “LOAD SETUP DEFAULTS” loads the values required by the system for maximum performance. Chapter 3 Award BIOS Setup 39 Integrated Peripherals Figure 3-6: Integrated peripherals 40 SBC-775 User’s Manual Password Setting To change the password: 1. Choose the "PASSWORD SETTING" option from the Setup main menu and press . The screen will display the following message: Enter Password: Press . 2. If the CMOS is good or if this option has been used to change the default password, the user is asked for the password stored in the CMOS. The screen will display the following message: Confirm Password: Enter the current password and press . 3. After pressing (ROM password) or the current password (user-defined), you can change the password stored in the CMOS. The password must be no longer than eight (8) characters. Remember, to enable the password setting feature, you must first select either Setup or System to secure your option in "BIOS FEA- TURES SETUP". IDE HDD Auto Detection "IDE HDD AUTO DETECTION" automatically self-detects for the correct hard disk type. Chapter 3 Award BIOS Setup 41 Save & Exit Setup If you select this and press , the values entered in the setup utilities will be recorded in the CMOS memory of the chipset. The microprocessor will check this every time you turn your system on and compare this to what it finds as it checks the system. This record is required for the system to operate. Exit Without Saving Selecting this option and pressing lets you exit the setup program without recording any new values or changing old ones. 42 SBC-775 User’s Manual A Programming the Watchdog Timer The SBC-775 is equipped with a watch- dog timer that resets the CPU or gener- ates an interrupt if processing comes to a stand-still for any rason.
