Step 3 Install Memory
The main memory subsystem on the Super Voyager VLB-III motherboard consists of four 32-bit SIMM
memory sockets. Each socket can hold one SIMM unit. One x 36 SIMM packages is the equivalent of four
x 9 SIMM packages (and is actually a bank of memory in itself). You can use 256 KB x 36, 512 KB x 36, 1
MB x 36, 2 MB x 36, 4 MB x 36, 8 MB x 36, or 16 MB x 36 SIMMs.
The SIMMs can be single-sided or double-sided. The Super Voyager VLB-III motherboard uses fast page
mode SIMMs operating at 70 ns (RAS access time).
Reporting Memory
The system memory is reported by AMIBIOS as it boots and again when the AMIBIOS System
Configuration Screen is displayed just before DOS is booted.
If the system has 8 MB of system memory, the memory reported by AMIBIOS is 128 KB less than the total
amount of memory installed in the system because some of the memory between 640K and 1024K is used
to shadow the video and system BIOS.
If the system has 16 MB of memory or more, the memory displayed by AMIBIOS on the System
Configuration Screen is 384 KB less than the total memory installed, because all of the memory between
640K and 1024K is used by AMIBIOS for shadowing.
