Memory Configuration
The mainboard supports two strips of
72-pin 5V FPM/EDO DRAM
(SIMM) from 4 to 32MB and two strips of 168-pin 3.3V/5V
Unbuffered DIMM modules from 8 to 128MB.
The mainboard
requires SIMM modules of at least 70ns access time.
You can install memory in any combination without having to rely on a
memory configuration table. memory configuration is thus Ò
Table-Free
Ó
in any memory bank. You must install two SIMM modules to complete
a bank.

installed SDRAM type of DIMM.
