Step 2 Install System Memory,
Installing SIMMs
Six SIMM sockets are located near the power connector on the motherboard. These sockets can be
filled with either 256 KB x 36, 512 KB x 36, 1 MB x 36, 2 MB x 36, 4 MB x 36, or 8 MB x 36
SIMMs. Place the motherboard on an anti-static mat. With the component side of the SIMM facing
you, firmly push the SIMM into the socket at a 45 degree angle, then push it up to a vertical
position. When properly inserted, the SIMM clicks into place as the latching pins engage. See the
following figure.

Reporting Memory
The system memory configuration is reported by WinBIOS as it boots and again when the
WinBIOS System Configuration Screen is displayed just before the operating system is booted.
The memory reported by WinBIOS is 384 KB less than the total amount of memory installed in
the system because the memory between 640K and 1024K can be used to shadow the video,
system, and other adapter BIOS.
