III. INSTALLATION (Jumpers) III. INSTALLATION Installation Steps Before using your computer, you must complete the following steps: 1. Set Jumpers on the Motherboard 2. Install DRAM and SRAM Modules 3. Install the Central Processing Unit (CPU) 4. Install Expansion Cards 5. Connect Ribbon Cables, Cabinet Wires, and Power Supply 6. Setup the BIOS Software 1. Jumpers Several hardware settings are made through the use of jumper caps to connect jumper pins (JP) on the motherboard. See "Map of the M

JP14 JP14 III. INSTALLATION Jumper Settings 1. Total Level 2 Cache Size Setting (JP14) This jumper sets the total amount of L2 cache that is present. If you have both onboard cache chips (see "Map of Motherboard" for locations) and a Cache Expansion Slot, then you have 256KB. If you only have onboard cache chips, then you have 512KB. An "ASUS" or "COAST" cache module can be used to upgrade the 256KB version to 512KB. If there is no onboard cache, you may install a cache module of either 256

JP16 JP15 JP16 JP15 III. INSTALLATION (Jumpers) III. INSTALLATION 3. Memory Cacheable Size (JP15) The default of 64MB uses only the onboard TAG SRAM which allows cacheable memory up to 64MB. If you install DRAM above 64MB and wish to allow cacheable memory above 64MB, you need to install a TAG SRAM upgrade or use a cache module with an extended TAG SRAM (such as 256KB ASUS CM1 Rev 3.0 with 2 TAG SRAM's) but not both and set this jumper to 512MB. See page 12 for TAG SRAM upgrade and page 14 fo

III. INSTALLATION 5. CMOS RAM (JP17) This clears the user-entered information stored in the CMOS RAM of the Real Time Clock such as hard disk information and passwords. To clear the CMOS data: (1) Turn off the PC, (2) Set jumper to "Clear," (3) Power on the PC, (4) Turn off the PC, (5) Set jumper to "Operation," (6) Power on the PC, (7) Hold down during bootup and enter BIOS setup to re-enter user information.

III. INSTALLATION (Memory) III. INSTALLATION 2. System Memory (DRAM & SRAM) This motherboard supports four 72-pin SIMMs of 4MB, 8MB, 16MB, 32MB, or 64MB to form a memory size between 8MB to 256MB. The DRAM can be either 60ns or 70ns Fast Page Mode (Asymmetric or Symmetric) or EDO. To support ECC, you must use true (opposed to phantom parity generated by logic chips) 36-bit parity-type DRAM (e.g. 8 chips + 4 parity chips) in pairs for all modules. Mixing 32-bit non-parity DRAM (e.g. 8 chips)
