3.7 Hardware Reset Switch Connector Installation The RESET switch on your cases' display panel provides users with the HARDWARE RESET function which is the same as power on/off. The system will do a cold start after the RESET switch is pushed by the user. The RESET switch is a 2 pin connector and should be installed on jumper J45. 3.8 Flash EEPROM-Jumper J32 The S1668 uses flash memory to store BIOS data. It can be updated as new versions of the BIOS becomes available.
3.10 DRAM Installation The S1668 uses a 64-bit data path from memory to CPU and can accommodate up to 1024 MB of RAM. The mainboard supports standard, EDO (Extended Data Out) and ECC(Error Correcting Code) 72 pin SIMMS . All installed memory will be automatically detected so there is no need to set jumpers. SIMM modules must be installed in pairs. Each pair of SIMMs must be of the same size and type. The mainboard supports 1, 2, 4, 8, 16x32 or 32MBx32 SIMMS.

3.11 CPU Installation Many types of Pentium Pro (150 thru 200 MHz) CPUs can be used on the S1668. Please refer to the previous pages for the correct CPU jumper settings for your board. The CPU is a sensitive electronic component and it can be easily damaged by static electricity. Do not touch the CPU pins with your fingers. When installing the CPU into the socket, match the CPU pins to the socket pins.
3.12 VRM Installation The VRM is required for the Pentium Pro to work. The CPU will program the VRM for the correct voltage needed. No jumper settings are needed, just install the VRM into the VRM socket nearest the CPU that is being installed. The VRM can only fit in the socket one way so there is no danger of installing it incorrectly. Not all VRM's will work in the S1668. Make sure you purchased a qualified VRM. VRM socket 0 is for CPU socket 0. VRM socket 1 is for CPU socket 1. 3.
4. BIOS Configuration Award's BIOS has a built in setup program that allows the user to modify the basic system configuration. This type of information is stored in the battery-backed CMOS SRAM. Entering incorrect information or forgetting your password can lock you out of your system.(refer to 3.15 for resetting of CMOS) 4.1. Entering Setup Power ON the computer and press immediately and you will enter Setup.

Primary/Secondary Drive type This category identifies the types of hard disk drives that have been installed in the computer. There are 46 predefined types and a user definable type. Press PgUp or PgDn to select a numbered hard disk type or type a number and press . Note that the specifications of your drive must match with the drive table. The hard disk will not work properly if you enter improper information for this category.
Video This category detects the type of graphics adapter used for the primary display system. It must match your video display card and monitor. Although secondary monitors are supported, you do not have to select that type in setup. EGA/VGA CGA 40 CGA 80 Mono Enhanced Graphics Adapter/Video Graphics Array. For VGA,SVGA, or PGA monitor adapters. Color Graphics Adapter, power up in 40 column mode. Color Graphics Adapter, power up in 80 column mode. Monochrome adapter, includes hi-res monochrome.
Expanded Memory Expanded Memory (EMS) defines a 64 K page frame in the area between 640K and 1Mb containing four 16K pages that are windows into the EMS memory. Programs issue requests to the EMS manager to switch the page to any part of EMS memory. Extended memory can be converted to emulate EMS by using a memory manager such as EMM386 that ships with Windows and DOS. Other Memory This refers to memory located in the 640K to 1024K ad dress space. This memory can be used for different applications.
Virus warning This category flashes on screen. During and after the system boot up, any attempt to write to the boot sector or the partition table of the hard disk drive will halt the system and the following error message will appear. In the meantime, you can run an anti-virus program to locate the problem. Default value is Enabled. Enabled Activate automatically when the system boots up causing a warning message to appear when anything attemps to access the boot sector or hard disk partition table.
Boot Up Floppy Seek During POST, the BIOS will determine if the floppy disk drive installed is 40 or 80 tracks. 360K type is 40 tracks while 720K, 1.2M and 1.44M are all 80 tracks. Default value is Enabled Enabled BIOS searches for floppy disk drive to determined if it is 40 or 80 tracks. Note that the BIOS cannot tell from 720k, 1.2M or 1.44M drive type as they are all 80 tracks Disabled BIOS will not search for the type of floppy disk drive by track number.
Security Option This category allows you to limit access to the system setup, or just setup. Default value is Setup Sys tem The system password is Setup The system not entered will not boot and access to Setup will be denied if the correct not entered at the prompt will boot, but access to setup will be denied if the password is at the prompt PS/2 Mouse Function Enables or disables PS/2 mouse function. Default is Disabled.

5.0 Flash Writer Utility You can upgrade the BIOS of your mainboard by using a "Flash Memory Writer"(FMW) utility. This utility can be downloaded from the factory's BBS(Consult your system vendor for the phone #). The system BIOS is stored on a 'flash' EPROM chip on the mainboard which can be erased and reprogrammed by the FMW. The following three files make up the FMW. AWDFLASH.EXE AMIFLASH.COM README *S62AWXX.BIN -The Flash Memory Writer utility for Award to Award upgrade.
To reprogram the System BIOS, you must first do the following: 1. Check jumper J32 The S1668 uses a 5V Flash EPROM so jumper J32 should be left in the default postion on pins 1 and 2. This jumper should never be moved. 2. Make sure the CPU is running in ‘real mode’. FMW will not run if the CPU is operating in a protected or virtual mode. This means that you can not run it with Windows running or with any memory manager software. You must disable any memory manager first. The easiest way to do this is to: a.
Once you have satisfied the two requirements mentioned above, you can run FMW. You can copy the contents of the “Flash” directory to your hard drive, or you can run the utility from a backup of the support floppy disk. Make sure the new BIOS file is in the same directory as the FMW utility. To run FMW, change to the “Flash” directory if you are not already in it. Type “Awdflash” at the DOS command line and press the key. The following screen will appear. 5.
