To clear the RTC data: (1) Unplug your computer, (2) Short solder points, (3) Turn on your computer, (4) Hold down during bootup and enter BIOS setup to reenter user preferences. R III. INSTALLATION Jumpers RTC RAM R129 Clear CMOS [short solder points momentarily] R129 (Clear CMOS) P2L-M Clear RTC RAM 2.
III. INSTALLATION 3. CPU External (BUS) Frequency Selection (FS0, FS1, FS2) These jumpers tell the clock generator what frequency to send to the CPU. These allow the selection of the CPU’s External frequency (or BUS Clock). The BUS Clock times the BUS Ratio equals the CPU's Internal frequency (the advertised CPU speed). 4.
III. INSTALLATION 2. System Memory (DIMM) Only Dual Inline Memory Modules (DIMM) can be used with this motherboard. Two sockets are available for 3.3Volt (power level) Unbuffered Synchronous DRAMs (SDRAM) or EDO DRAM of either 8, 16, 32, 64, or 128MB. One side (with memory chips) of the DIMM module takes up one Row on the motherboard.
III. INSTALLATION DIMM Memory Installation Insert the module(s) as shown. Because the number of pins are different on either side of the breaks, the module will only fit in the orientation as shown. DIMM modules are longer and have different pin contact on each side and therefore have a higher pin density. SIMM modules have the same pin contact on both sides. R 20 Pins 60 Pins 88 Pins III. INSTALLATION System Memory Lock FRONT P2L-M 168-Pin DIMM Sockets The DIMMs must be 3.
III. INSTALLATION 3. Central Processing Unit (CPU) This motherboard provides a Single Edge Contact (SEC) slot for a Pentium II processor packaged in an SEC cartridge or for a Celeron processor in a Single Edge Processor Package (SEPP). Pentium II Processor WARNING! Be sure that sufficient air circulation is available across the processor’s passive heatsink. Without sufficient circulation, the processor could overheat and damage both the processor and the motherboard.
III. INSTALLATION The Motherboard As Shipped Four screws should be showing next to each corner of the SEC CPU Slot using two attach mount bridges from the underside of the motherboard (only for Pentium II). (1) SEC CPU slot NOTE: Encircled items are screws from the mount bridges (1 & 2) (2) III. INSTALLATION CPU Installing the Pentium II Processor: 1. Mount the Pentium II Retention Mechanism: The retention mechanism is designed to fit into the SEC slot only one way.
III. INSTALLATION 2. Mount the Heatsink: Place the SEC cartridge face down on a flat surface and lay the heat sink flush on the back (metal side) of the SEC cartridge. Check the orientation of the heatsink against the pictures. The thicker fin must be orientated toward the bottom. The top clamp is wider than the bottom clamp so only this orientation will fit. With a screw driver, push the clamps one at a time into the SEC cartridge. Be sure that the heatsink is firmly pressed against the SEC cartridge.
III. INSTALLATION 4. Secure the SEC Cartridge: Secure the SEC cartridge in place by pushing the SEC cartridge locks outward so that the lock shows through the retention mechanism’s lock holes. (3) (3) (8) III. INSTALLATION CPU 5. Secure the Heatsink: Install the heatsink support base into the motherboard. This is not, however, necessary if you use a heatsink with fan (see next page). The support base is necessary to secure the heatsink (without fan).
III. INSTALLATION The heatsinks shown in this manual are for reference purposes only. The recommended heatsinks for the Pentium II processor are those with three-pin fans that can be connected to the CPU fan connector on motherboard. These heatsinks have the added benefits of proper heat dissipation and with the hardware monitor, the ability to monitor the fan’s RPM and use the alert function through the included LANDesk Client Manager (LDCM) software.
