Setting jumpers You can 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 will have three pins, labeled 1, 2, and 3. In this case you would connect either pins 1 and 2 or 2 and 3.
CPU installing and upgrading You can upgrade to a more powerful Celeron CPU at any time. Simply remove the old CPU, install the new one, and set the jumpers for the new CPU speed. Warning! Always disconnect the power cord from your chassis when you are working on it. Do not make connections while the power is on as sensitive electronic components can be damaged by the sudden rush of power. Only experienced electronics personnel should open the system chassis.
3. Press the lever down. The plate will slide forward. You will feel some resistance as the pressure starts to secure the CPU in the socket. This normal and won't damage the CPU. When the CPU is installed, the lever should snap into place at the side of the socket. Note: To remove a CPU, pull the lever out to the side a little and raise it as far as it will go. Lift out the CPU chip. When you install a new CPU, be sure to adjust the board settings, such as CPU type and CPU clock.
Installing SDRAM (DIMMs) System Memory The upper edge of the SBC-656 contains one sockets for 168 pins dual inline memory module (DIMM). The socket uses 3.3 V unbuffered synchronous (SDRAM). DIMM is available in capacities of 16, 32, 64, 128, or 256 MB. The socket can be filled in the DIMM of any size, giving your SBC-656 single board computer between 16 and 256 MB of memory. Supplementary information about DIMM Your SBC-656 can accept both regular and PC-100 SDRAM DIMM Module(with or without parity).
Cache memory Since the second level cache has been embedded into the Celeron CPU, you do not have to take care of either SRAM chips or SRAM modules. The built-in second level cache in the Celeron yields much higher performance than the external cache memories. The cache size in the Celeron CPU is either 128 KB.
DOC address & CPU frequency ratio select SW1 (A, B, C, D, E, F) DOC address select The DiskOnChip 2000 occupies a 8KB window in the upper memory address range of D400 to DC00. You should ensure this does not conflict with any other device's memory address. SW1 (B, C) controls the momory address of the Flash disk.
CPU frequency ratio select CPU core frequency = CPU frequency ratio (3~5.5) * External bus clock (66 or 100 MHz) CPU frequency ratio select SW1 (D, E, F) 3X 4.5X * A B C D E F 5X A B C D E F ON A B C D E F 5.5X ON ON A B C D E F 4.0X ON A B C D E F ON ON A B C D E F 3.5X * default Note: Most Celeron CPUs' frequency ratio are pre-locked within the CPUs. Thess CPUs run at fixed speed (frequency) regardless of the configurations listed above.

CHAPTER 3 Award BIOS Setup This chapter describes how to configure the BIOS for the system.
Starting setup The Award BIOS is immediately activated when you first turn on the computer. The BIOS reads system configuration information in CMOS RAM and begins the process of checking out the system and configuring it through the power-on self test (POST). When these preliminaries are finished, the BIOS seeks an operating system on one of the data storage devices (hard drive, floppy drive, etc.). The BIOS launches the operating system and hands control of system operations to it.

For drives with greater than 1024 cylinders. Drive A Drive B Select the correct specifications for the diskette drive(s) installed in the computer. None 360K, 5.25 in 1.2M, 5.25 in 720K, 3.5 in 1.44M, 3.5 in 2.88M, 3.
Pannel: This selection item allow user to select LCD BIOS to match the LCD types.
Halt On During the power-on-self-test (POST), the computer stops if the BIOS detects a hardware error. 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 errors. • All errorsIf: 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.
•Extended Memory Above the 1-MB boundary. Early IBM personal computers could not use memory above 1 MB, but current PCs and their software can use extended memory. •Other Memory Between 640 KB and 1 MB; often called High memory. DOS may load terminate-and-stay-resident (TSR) programs, such as device drivers, in this area, to free as much conventional memory as possible for applications. Lines in your CONFIG.SYS file that start with LOADHIGH load programs into high memory.
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 antivirus 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.
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 operating instructions that come with some expansion peripherals, such as, for example, 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 8bit X-bus.
CHIPSET features setup By choosing the CHIPSET 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. This section allows you to configure the system based on the specific features of the installed chipset. This chipset manages bus speeds and access to system memory resources, such as SDRAM. It also coordinates communications between the conventional ISA bus and the PCI bus. It must be stated that these items should never need to be altered.
SDRAM Precharge Control When Enabled, all CPU cycles to SDRAM result in an All Banks Precharge Command on the SDRAM interface. DRAM Data Integrity Mode Select Non-ECC or ECC (error-correcting code), according to the type of installed DRAM. 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.
Memory Hole at 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 information of peripherals that need to use this area of system memory usually discusses their memory requirements. Passive Release When Enabled, CPU to PCI bus accesses are allowed during passive release. Otherwise, the arbiter only accepts another PCI master access to local DRAM.
Power management setup By choosing the POWER MANAGEMENT option from the INITIAL SETUP SCREEN menu, the screen below is displayed.
The displayed configuration is based on the manufacturer's SETUP DEFAULTS settings. Power Management This option allows you to select the type (or degree) of power saving for Doze, Standby, and Suspend modes. This table describes each power management mode: Max Saving User Define Min Saving 68 SBC-656 User Manual Maximum power savings. Only Available for SL CPUs. Inactivity period is 1 minute in each mode. Set each mode individually. Select time-out periods in the section for each mode, below.
PM Control by APM If Advanced Power Management (APM) is installed on your system, selecting Yes gives better power savings. Video Off Method Determines the manner in which the monitor is blanked. V/H SYNC+Blank System turns off vertical and horizontal synchronization ports and writes blanks to the video buffer. DPMS Support Select this option if your monitor supports the Display Power Management Signaling (DPMS) standard of the Video Electronics Standards Association (VESA).
Standby Mode After the selected period of system inactivity, the CPU clock stops, the hard drive enters an idle state, and the L2 cache enters a powersave mode. All other devices still operate at full speed. Suspend Mode After the selected period of system inactivity, the chipset enters a hardware suspend mode, stopping the CPU clock and possibly causing other system devices to enter power management modes.
Reload Global Timer Events When Enabled, an event occurring on each device listed below restarts the global timer for Standby mode.
PNP/PCI configuration setup By choosing the PNP/PCI CONFIGURATION 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. NOTE: This chapter describes all fields offered by Award Software in this screen. Your system board designer may omit or modify some fields. PNP OS Installed Select Yes if the system operating environment is Plug-and-Play aware (e.g., Windows 95). Resources Controlled By The Plug and Play AwardBIOS can automatically configure all the boot and Plug and Play-compatible devices.
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 system on.
Integrated peripherals setup By choosing the INTEGRATD PERIPHERALS option from the initial SETUP SCREEN menu, the screen below is displayed.
The displayed configuration is based on the manufacturer's SETUP DEFAULSTS settings. IDE HDD Block Mode Select Enabled only if your hard drives support block mode. IDE Primary Master/Slave UDMA UDMA (Ultra DMA) is a DMA data transfer protocol that utilizes ATA commands and the ATA bus to allow DMA commands to transfer data at a maximum burst rate of 33 MB/s.
RxD, TxD Active Consult your IR peripheral documentation to select the correct setting of the TxD and RxD signals. ECP Mode Use DMA Select a DMA channel for the port. EPP Mode select Select EPP port type 1.7 or 1.9.
Supervisor/User password setting You can set either SUPERVISOR or USER PASSWORD, or both of them. The difference between the two is that the supervisor password allows unrestricted access to enter and change the options of the setup menus, while the user password only allows entry to the program, but not modify options.
When you select this function, a message appears at the center of the screen: ENTER PASSWORD: Type the password, up to eight characters, and press Enter. Typing a password clears any previously entered password from CMOS memory. Now the message changes: CONFIRM PASSWORD: Again, type the password and press Enter. To abort the process at any time, press Esc.
IDE HDD auto detection The IDE HDD AUTO DETECTION utility can automatically detect the IDE hard disk installed in your system. You can use it to selfdetect and/or correct the hard disk type configuration.
Save & exit setup If you select this option and press , the values entered in the setup utility will be recorded in the chipset's CMOS memory.

To configure the medium type, to view the current configuration, or to run diagnostics, please refer to the following instruction: 1. Power the mainboard on. Ensure that the RSET8139.EXE file is located in the working drive. 2. At the prompt, type RSET8139.EXE and press .
APPENDIX A Programming the Watchdog Timer The mainboard is equipped with a watchdog timer that resets the CPU or generates an interrupt if processing comes to a standstill for whatever reason. This feature ensures system reliability in industrial stand-alone and unmanned environments.
Programming the watchdog timer Watchdog timer The watchdog timer uses a 8-bit counter. The time range is from 32 seconds to 254.5 min with a resolution of 1 min. When timer times out, a system reset will happen. Configuration register The watchdog timer of SBC-656 is located on the chipset – Winbond W83977. If you want to use it, you have to know how to read/ write the configuration register of W83977. The basic procedure is as follows. 1. Enter configuration mode. 2. Select Logical Device. 3.
How to set the watchdog timer 1.Set register 30h of logical device 7 to 1 to activate the timer. 2.Write the desired counter value to register F2h of logical deivice 8. Logical Device 7 : Register number 30h (CR30) 00h : timer inactive 01h : timer active Logicel Device 8 : Register number F2h (CRF2) 00h : Time-out Disable 01h : Time-out occurs after 32 seconds 02h : Time-out occurs after 1 minute 32 seconds 03h : Time-out occurs after 2 minute 32 seconds 04h : Time-out occurs after 3 minute 32 seconds ....
Example Following is an example of programming 32 sec period for watchdog timer in assembly language. When timer times out, it will generate signal of system reset.
