Video Memory Upgrade

Larger video memory allows you to display higher resolutions and
more colors.  The system board comes with a 1-MB video memory
onboard upgradable to 2 MB.

Follow these steps to upgrade the video memory:

1.

Locate the video DRAM upgrade sockets labeled U39 and U40
on the system board.  See Figure 1-1.

2.

Gently insert a 256K x 16, 60 ns EDO SOJ) chip into each of the
upgrade sockets.

Make sure that the pin 1 indicator on the chip
matches the notched corner of the socket.
