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 heat
sink 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." See the figure at the beginning of this section for the location
of the Slot 1 connector.
