    Board Installation Unpacking The mainboard package should contain the following: (1) S1590 mainboard (1) 40-pin IDE and 34-pin floppy cable pack (1) S1590 User’s Manual ( 1 ) Serial/parallel cable set ( 1 ) PS/2 mouse cable (1) Driver CD Installation You are now ready to install your mainboard.
  • Page 10 Install the motherboard into your case. Follow the instructions provided by the case manufacturer for proper installa- tion guidelines. TYAN recommends that you use only one screw to hold down the motherboard. The rest of the mounting holes should be used for the plastic standoffs.
  • Page 11 Note: Tyan recommends using an ATX power supply that conforms to industry standard revision 2.01.
  • Page 12 Hard drive lights are constantly on: bad IDE cable or defective drive or motherboard. Try another HDD. • Hard drives do not power up: check power cables and cabling. May also be a bad power supply or IDE drive. http://www.tyan.com...
  • Page 13 Figure 4 Now that you have installed your IDE drives, your floppies are next. Pin 1 on the floppy cable is usually denoted by a red or colored stripe down one side of the cable (see Figure 6). Most of the current floppy drives on the market require that the colored stripe be positioned so that it is right next to the power connector.
  • Page 14 IBM standard pinouts and will differ from most other manufacturers’. 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.
  • Page 15 Com2 is supplied seperately on a second back plate (Figure 9). Remem- ber: Only TYAN cables will work on this motherboard. If you are using an existing case with old cables, your system will not function properly. Use only TYAN-approved connectors.
  • Page 16 Because of this, your memory may not work correctly in a TYAN board though it may work well in a competitor’s board. http://www.tyan.com...
  • Page 17 This is because many of our competitors do not adhere to the strict tolerances required for high performance. If you buy a TYAN board, you are getting the best system available. To make installation easy and trouble free, get high quality parts.

    Glossary ACPI (Advanced Configuration and Power Interface) is a power management specification that allows the operating system to control the amount of power distributed to the computer’s devices. Devices not in use can be turned off, reducing unnecessary power expenditure. (Accelerated Graphics Port) is a PCI-based interface which was de- signed specifically for demands of 3D graphics applications.

  • Page 67 Latency is the amount of time that one part of a system spends waiting for another part to catch up. This is most common when the system sends data out to a peripheral device, and is waiting for the peripheral to send some data back (peripherals tend to be slower than onboard system components).
