Step 6 Install CPU
The Pentium II CPU is on an Intel Slot1 adapter card. Insert the Slot1 card
into the CPU card socket on the motherboard. See the motherboard drawing
for the CPU Slot1 location.
Warning
Improper CPU installation can damage the CPU and the
motherboard. You must follow the procedures in this
section exactly as documented. Make sure you wear an
antistatic wristband while installing the CPU. Follow all
antistatic procedures.
Step 7 Install Memory
System Memory There are six 32-bit SIMM (Single Inline Memory Module) sockets. System
memory must be populated one bank at a time. Each bank has two sockets.
Each bank must be populated with the same type of SIMM. If a 4 MB SIMM
is installed in the first socket in Bank0, then the same type of 4 MB SIMM
must be installed in the second Bank0 SIMM socket. The minimum amount
of system memory supported by the Pegasus PCI is 8 MB. Each socket can
hold one SIMM. You can use:
• 1 MB x 32 (or 36),
• 2 MB x 32 (or 36),
• 4 MB x 32 (or 36),
• 8 MB x 32 (or 36),
• 16 MB x 32 (or 36), or
• 32 MB x 32 (or 36) SIMMs.
The Pegasus motherboard will support 128 MB SIMMs when they become
available, permitting up to 768 MB of system memory to be installed on the
motherboard. Fast Page Mode, EDO, and Burst EDO SIMMs cannot be
mixed. The motherboard supports SIMMs operating at 60 ns (RAS access
time).
