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. 
 
DRAM Combination Configuration: 

32MB NIL  32MB 
32MB 32MB  64MB 
32MB 64MB  96MB 
32MB 128MB  160MB 
64MB NIL  64MB 
64MB 32MB  96MB 
64MB 64MB  128MB 
64MB 128MB  192MB 

128MB NIL  128MB
