  • Page 11 Install the motherboard into your case. Follow the instructions provided by the case manufacturer for proper installation 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. If your case does not have a hole for a standoff, simply cut off the bottom of the plastic standoff so that the flat portion rests on the metal.

Note that USB requires Windows 95 OSR 2.1 or above; please contact Microsoft for the USB update.

  • Page 34: Ram Installation

    Some details of memory installation: One unbuffered DIMM must be installed for the system to POST. The mainboard supports 8MB, 16MB, 32MB, 64MB, 128MB, and 256MB SDRAM DIMM modules. The table on the following page shows some of the possible memory configurations. http://www.tyan.com...

  • Page 35: Cache Memory

    Penitum II processors have the L2 (Level 2) cache built into their architecture, so there is no need for an L2 cache on the motherboard. The Pentium II processor has a phsyical L2 cache size of 512KB and a cacheable memory area of 512MB. http://www.tyan.com...

  • Page 36: Frequently Asked Questions

    Q: Can I use EDO DIMMs on this motherboard? A: No. The Intel 440BX AGPset does not support EDO memory. The 440BX AGPset supports bus speeds of 100MHz, and EDO memory does not. You must use SDRAM (which does support 100MHz bus speeds) on this board. http://www.tyan.com...
  • Page 37 Q: Does my operating system support AGP? A: Currently, only Windows 98 and Windows NT 5.0 will have built-in support for AGP. Some AGP cards require Windows 95 OSR2.1 or a special driver from Intel. Please check with your graphics vendor for more details. http://www.tyan.com...
