Adding more video memory
Video memory is memory reserved for use by the on-board
controller. More video memory provides more colours or higher
resolutions (provided that your monitor can cope).
If your computer has 1 Mbyte of video memory, you can upgrade it
to the maximum of 2 Mbytes.
To add video memory:
1. Turn off the computer and unplug all power cords.
2. Take suitable anti-static precautions and remove the system
unit cover.
If you are unfamiliar with the recommended anti-static
precautions or the process of removing the system unit cover,
refer to Appendix A, “Inside the System Unit”.
3. If there are any expansion cards fitted, you will have to remove
them: disconnect any cables connected to the cards, remove the
screws that secure the cards to the rear of the system unit, then
remove the cards from the system unit.
4. Use the illustration at the beginning of this chapter to identify
the two video memory upgrade sockets.
5. Unpack the upgrade kit and lay the memory chips out on an
anti-static surface. Hold each chip by its edges and be careful
not to touch the metal pins.
6. One by one, insert the chips in the sockets.
It is important that the chips are fitted the right way round.
Some chips have a single bevelled edge at one end. Others
have a small semicircular notch at one end and a bevel at one
corner. In either case, the bevelled or notched end must be
aligned with the bevelled corner on the socket itself, as shown
in the following illustration.
