III. INSTALLATION Jumper Settings 1. Clear Real Time Clock (RTC) RAM (CLRTC) The CMOS RAM is powered by the onboard button cell battery. To clear the RTC data: (1) Turn off your computer and unplug its AC power, (2) Short the two solder points labeled CLRTC, (3) Turn on your computer, (4) Hold down during bootup and enter BIOS setup to re-enter user preferences. Short the solder points to clear CMOS P2B-D2 Real Time Clock RAM (CLRTC) 2. i960 Bridge Setting The secondary PCI slots can f

III. INSTALLATION Jumpers III. INSTALLATION 4. CPU Bus Frequency (FS0, FS1, FS2) This option tells the clock generator what frequency to send to the CPU, DRAM, and 440BX AGPset. This allows the selection of the CPU’s External frequency (or BUS Clock). The BUS Clock multiplied by the BUS Ratio equals the CPU’s Internal fre- quency (the advertised CPU speed). 5. CPU Core:BUS Frequency Multiple (BF0, BF1, BF2, BF3) This option sets the frequency multiple between the Internal frequency of the CPU

III. INSTALLATION System Memory III. INSTALLATION 2. System Memory Main Memory (DIMM) This motherboard supports Dual Inline Memory Modules (DIMMs). Sockets are avail- able for 3.3Volt (power level) unbuffered Synchronous Dynamic Random Access Memory (SDRAM). One side (with memory chips) of the DIMM takes up one row on the motherboard. To utilize the chipset’s Error Checking and Correction (ECC) feature, you must use a DIMM module with 9 chips per side (standard 8 chips/side + 1 ECC chip) and m

III. INSTALLATION i960 Memory III. INSTALLATION i960 Memory (SIMM) The i960 processor supports two 72-pin, 32-bit SIMMs (Single-Inline Memory Modules) of 4, 8, 16, 32, 64, or 128MB to form a memory size between 8MB to 256MB. Only Extended Data Output (EDO) DRAM, non-parity SIMMs can be sup- ported by the i960 processor. IMPORTANT: You must use i960 SIMM socket 1 when using only one module. SIMM Installation 1. The SIMM memory modules will fit in only one orientation as shown because the plastic
