to open the Setup utility before POST. Set
the BIOS settings (see Section 2).
Upgrade Sockets
The system board has the following upgrade sockets:
processor socket
DIMM sockets.
See the following paragraphs for socket descriptions.
Processor Socket
The processor socket is designed for easy processor upgradeability through use
of a Single Edge Contact (S.E.C.) cartridge. The cartridge contains the
processor, second level cache, thermal plate, and back cover. In addition, a
heatsink is connected to the cartridge.
The 242-pin edge connector socket (Slot 1) on the system board holds the
processor S.E.C. cartridge. The cartridge is held in place in the socket by a
retention mechanism. With the cartridge plugged into the socket, the processor’s
pins automatically set the system board voltage regulator and processor speed
(66 MHz or 100 MHz).
To remove or install a processor S.E.C. cartridge, see Section 3, “Disassembly
and Reassembly.” Pin assignments for the processor socket are included at the
end of this section.
DIMM Sockets
The system board has three, 168-pin, gold-plated DIMM sockets (locations are
shown on the figure at the beginning of this section). The sockets support up to
384 MB of high-speed SDRAM memory. The sockets support DIMM modules
in 16-, 32-, 64-, and 128-MB 66-MHz and 100-MHz memory configurations.
Use these guidelines when selecting DIMMS:
DIMMs can be installed in one, two, or three sockets
DIMM size can vary between sockets
DIMM speed must match the processor bus speed (66 MHz or 100 MHz)
Single- and double-sided DIMMs can be mixed.
See the following tables for supported DIMMs and for sample DIMM upgrade
paths. To determine the memory needed for a memory upgrade, see “Checking
System Memory.”
