    Introduction Introduction Overview The S1590S-100 (S1590) Trinity 100AT is a quality, high performance mainboard designed for Socket 7 microprocessors. This mainboard utilizes the VIA MVP3 100MHz AGPset and host bus speeds of 66MHz to 100MHz. For CPU speed support, please refer to the CPU Compatibility Chart in Tyan’s website (http://www.tyan.com/support/html/socket_7_compatibility.html).

    Place the DIMMs in an anti-static bag as soon as you remove them to avoid static damage. The Trinity 100AT uses a 64-bit data path from memory to CPU and can accommodate up to 384MB of SDRAM. The 168-pin DIMMs (Dual In-line Memory Modules) must be of the 3.3V, unbuffered variety.

  • Page 19

    • The mainboard supports 4MB, 8MB, 16MB, 32MB, and 64MB SIMMs. • You can install either single- or double-sided SIMMs. • Two SIMMs or one unbuffered DIMM must be installed for the system to S1590 Trinity 100AT...

  • Page 24: Connecting The Power Supply

    6. Connecting the Power Supply The Trinity 100AT has both AT and ATX power supply connectors. The photos below show the ATX power connector before (Figure 2-12) and after (Figure 2-13) it has been plugged in. The plastic clip on the power connector should lock over the plastic tab on the onboard connector.

  • Page 25

    Note: If you use an ATX power supply, Tyan recommends using one that conforms to industry standard revision 2.01. If you decide to use an AT power supply instead, connect the power supply to the board as shown in Figure 2-14 (on the following page).

  • Page 26: Installing Add-on Cards

    Before turning on the system, make sure no cards are touching If you follow these basic guidelines, there shouldn’t be any problems with installation. However, if you do encounter any problems, have a qualified professional install your cards for you or contact your card manufacturer. http://www.tyan.com...

  • Page 27

    Figure 2-15 Other cables will not work on TYAN boards. The Printer and Com1 ports are on the same back plate. You want to make sure that you correctly align the connectors with the pins on the board beacuse they are easy to miss. On most TYAN cables, there should be a pin missing on the motherboard.

    You can upgrade the BIOS on your motherboard by using the Flash Memory Writer (FMW) utility. This utility can be downloaded from TYAN’s BBS and from the TYAN website. The system BIOS is stored on a flash EEPROM chip on the mainboard, which can be erased and reprogrammed by the FMW. The following three files make up the FMW: AWDFLASH.EXE...
