2.1 Unpacking The mainboard package should contain the following: wS1668 Mainboard wOne IDE 40 pin cable wOne 34 pin floppy cable wUser's Manual wOptional VRM(Voltage Regulator Module) The mainboard contains sensitive electric components which can be easily damaged by static electricity, so the mainboard should be left in its original packaging until it is ready to be installed. With the power supply pluged in and turned off touch an unpainted area of the system chassis imedietly before handling the mainboard or any compo- nent. Doing so discharges the static charge your body may have built. After opening the mainboard carton, extract the system board holding it by its edges ,and place it only on a grounded anti-static surface, component side up. Inspect the board for damage. Press down on all of the socket IC's to make sure that they are properly seated. Do this only with the board placed on an anti-static mat. Do not touch the bottom of the board. DO NOT APPLY POWER TO THE BOARD IF IT HAS BEEN DAMAGED! 2.2 Installation You are now ready to install your mainboard. The mounting hole pattern of the S1668 matches the ATX system board spec. It is assumed that the chassis is for a standard ATX mainboard form factor.

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 S1668 provides a 4-Pin header (J43) to connect the speaker. The polarity can go either way. 3.5 Turbo Switch The front panel on your case may have a turbo switch to control system speed when slower program execution is required for software developed in the old XT days. The Intel 44FX chipset doesn't support a de-turbo mode, but the S1668 has a connector (J47) for the cable that may come has a connector (J47) for the cable that may come with the case.with the case. 3.6 Turbo LED Connector Installation The TURBO LED on the front case panel can indicate the current speed status of the system. The TURBO LED connector should be installed to J42 in the correct direction.

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. The flash utility will guide you through the process step by step. If your system is functioning properly, you may want to forego updating your BIOS in the event the new one causes problems with your existing hardware and software. J32 determines which type of EPROM is used. This jumper has been set to match the on board BIOS chip. The factory default for the S1668 is on pins 1-2. Refer to chapter 6 for Flash EEPROM upgrade procedures. 3.9 Hardware CMOS & Password Reset (The following steps are valid provided the board has a DS12887A RTC) If you have been locked out of your system because you forgot your pass- word or set the CMOS incorrectly, follow the instructions below. a. Power off the system b. Short jumper J41. c. Wait for 5 seconds then remove the jumper from J41. d.Then power on the system again. By doing the above procedures, your password will be erased and the CMOS will be reset to the BIOS defaults.

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. wSIMM modules must be installed in pairs. wEach pair of SIMMs must be of the same size and type. wThe mainboard supports 1, 2, 4, 8, 16x32 or 32MBx32 SIMMS. wThe table on the following page shows some of the available memory configurations. Voltage ID for Older Pentium Pro CPU's: J10 and J20 Most Pentium Pro CPU's will program the VRM to output the correct voltage it requires, so these jumper are not important and should be left open. Some early versions of the Pentium Pro cannot program the VRM so you have to set these jumper manually. J10 and J20 each have eight pins and are numbered as follows. 5 6 7 8 1 2 3 4 Pin # 4--8 3-7 2-6 1-5 3.5V on on on on 3.4V on on on off 3.3V on on off on 3.2V on on off off 3.1V on off on on 3.0V on off on off 2.9V on off off on 2.8V on off off off 2.7V off on on on 2.6V off on on off 2.5V off on off on 2.4V off on off off 2.3V off off on on 2.2V off off on off 2.1V off off off on Default off off off off

to the side a little and raise it as far as it will go. The top plate will slide back. 2. Align the CPU and socket Pin 1 corners. The pins on the bottom of the CPU should align with the rows of holes in the socket. 3. Insert the CPU in the socket. It should insert easily. If it does not, adjust the position of the lever a little. 4. Press the lever down. The top plate will slide forward. You will feel some resistance as the pressure starts to secure the CPU in the socket. This is normal and will not damage the CPU. When the CPU is installed, the lever should snap into place at the side of the socket in the down position. 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. 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 in order to avoid being broken by the pressure of CPU insertion. w A cooling fan and heat sink assembly is required to protect the CPU from being damaged.

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. w VRM socket 0 is for CPU socket 0. w VRM socket 1 is for CPU socket 1. again, and prepare to power-on the system. 3.14 Connecting the Power Supply & On/Off Switch The system power supply connectors on the mainboard is for a standard ATX power supply. It can only be plugged in one way and should install in easily. ATX cases have an on/off switch that can be used to turn on or off the ATX powersupply without having to use the switch that is on the back of the powersupply.Use jumper J1 is for the on/off button from the system case. 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 four PCI-Bus slots can support either a Master or a Slave device. After installing the peripheral controller, the user should check everything

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.

Base Memory The POST of the BIOS will determine the amount of base (or conventional) memory installed in the system. The value of the base memory is typically 640K. Extended Memory The BIOS determines how much extended memory is present during the POST. This is the amount of memory located above 1MB in the CPU's memory address map.

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. DOS uses this area to load device drivers to keep as much conventional memory free for application programs as possible. 4.6. BIOS FEATURES SETUP ROM ISA BIOS BIOS FEATURES SETUP AWARD SOFTWARE, INC.

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 -The Flash Memory Writer utility for Award to Award upgrade. AMIFLASH.COM -The Flash Memory Writer utility for AMI to AMI upgrade. README -A text file of instructions *S62AWXX.BIN -XX-A 2-digit version number. Flash memory writer records (or ‘programs’) a new BIOS onto the flash memory chip. You cannot upgrade an Award BIOS to a AMI BIOS or a AMI BIOS to an Award BIOS. *This file name is subject to change and can have either a "bin" or a "rom" extension.

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. Boot your system from a bootable floppy disk with no CONFIG.SYS or AUTOEXEC.BAT files, and then run Flash Memory Writer from a backup copy of your support disk. You can make your back-up floppy bootable when you format it, and use one disk for both purposes. b. If you are using MS-DOS 6.x, you can use the feature that allows you to bypass the CONFIG.SYS and AUTOEXEC.BAT file. You do this while pressing while the “Starting MS- DOS...” line is on the screen. There are other ways to accomplish the same result. The main point is to make sure no memory managers are running. If you are not sure, try running FMW. If it runs, then you have suc- ceeded. If it displays a warning message about the CPU mode, you will have to try again.

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 thesame directory as the FMW utility. To run FMW, change to the “Flash” directory if you are not al- ready in it. Type “Awdflash” at the DOS command line and press the key. The following screen will appear. 5.1 The Flash Memory Writer Utility Screen (Award) Type in the whole file name, e.g. A62AW10.BIN and confirm that you want to program the BIOS. The utility will then ‘Blank’, ‘Erase’, and then ‘Program’ the flash memory on the mainboard with the new BIOS file. You should choose “yes” to save the original system BIOS to a floppy diskette before you program the new BIOS. This leaves you with a backup of your original BIOS in case you need to re- install it. This option is highly recommended. If you can not sucessfully program the BIOS file for whatever reason, re-install you original BIOS from the backup file. Warning: If you do not successfully install a complete BIOS file in the flash memory on the Mainboard, your system may not be able to boot. If this happens, it will require service by your system vendor. Follow the requirements and instructions in this section precisely to aviod inconvenience.
