3.3.2 System Memory
The system memory consists of SDRAM memory on 64-bit bus and the module size options
are 128/256/512MB upward. 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 must be done in a way that requires no user interaction.
