3.3 CMOS RTC CMOS RTC includes an internal battery and Real Time Clock circuit. It provides the date and the time for the system. Normally the life span of a RTC internal battery is 10 years. When replacing, you should use the same model. 3.4 Speaker Connector Installation S1472 provides a 4-Pin header (J48) to connect the speaker. The polarity can go either way. 3.
3.7 Hardware Reset Switch Connector Installation The RESET switch on your cases' display panel provides users with the HARDWARE RESET functinon 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 J49. 3.8 Flash EPROM-Jumper J46 The S1472 uses flash memory to store BIOS programs. It can be updated as new versions of the BIOS becomes available.
3.10 DRAM Installation The S1472 uses a 64-bit data path from memory to CPU and can accommodate up to 128 MB of RAM. The mainboard supports Fast Page Mode, and EDO (Extended Data Out) 72 pin SIMMs. SDRAM(Synchronous) are also supported in the DIMM slots. DIMM's must be of the unbuffered variety. All installed memory will be automatically detected so there is no need to set jumpers. wSIMM modules must be installed in pairs. wEach pair of SIMMs must be of the same size and type.
3.11 CPU Installation Several types of CPUs (75 thru 200MHz) can be used on S1472. Please refer to section 3.2 for the correct CPU jumper settings for your board. w 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. w When installing the CPU into the socket, match the CPU pins to the socket pins. w Before the CPU is installed, the mainboard must be placed on a flat plane.
3.12 Upgrading Cache Memory The S1472 has 256Kb of on-board pipelined burst SRAM and can be upgraded to 512Kb by adding a Tyan approved 256Kb cache module. Please refer to your vendor for the approved upgrade modules. wRefer to page 9 for the cache jumper settings. wWhen upgrading to 512Kb cache, you must use a 256Kb "COAST" module and open jumper J8 and put jumper J7 on pins 1-2 wOnly use Tyan approved 256Kb "COAST" modules when upgrading.
3.13 Peripheral Device Installation After all the jumpers on the mainboard have been set, then it can be mounted into the case. Then proceed to install the display card and any other peripheral devices. If a PCI-Bus interface card is to be installed in the system, any one of the five PCI-Bus slots can support either a Master or a Slave device. After installing the peripheral controllers, the user should check everything again, and prepare to power-on the system. S1472-001-01 http://www.tyan.
4. BIOS Configuration Award's BIOS has a built in setup program that allows the user to modify battery-backed CMOS SRAM. Entering incorrect information or forgetting your password can lock you out of your system.(refer to 3.9 for resetting of CMOS) 4.1.

Expanded Memory Expanded Memory (EMS) defines a 64K 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.
w 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.
w 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 determind 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.
w Security Option This category allows you to limit access to the system setup, or just setup. Default value is 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 password is not entered at the prompt w Video BIOS Shadow It determines whether Video BIOS will be copied to RAM, however, it is an optional chipset design. Default is Enabled. 4.

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 ROM 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 *S72AWXX.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 J46.(Default pins 1-2) The S1472 uses a 5V Flash EPROM so jumper J46 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.
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.
