3.3.2 System Memory
The system memory consists of PC100 SDRAM memory on 64-bit bus and the module size
options are 16/32/64/128MB. PC100 SDRAM synchronizes itself with the CPU bus speed so
if the CPU is set at 100MHz-bus speed, the memory speed is also running at 100MHz. The
BIOS will automatically detect the amount of memory in the system and configure CMOS
accordingly during the POST (Power-On Self Test) process. This is done in a way that
requires no user interaction.
