System Memory
The system memory consists of SDRAM memory on 64-bit bus and the module
size options are 16/32/64MB. 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.
