Switches 3 and 4 (Memory size)-indicate how much built-in memory is available. You only change these switches if you install a memory card and you want to use part of the optional memory instead of the built-in main memory. The factory setting is switch 3 OFF; switch 4 ON. Because the system checks the amount of available memory each time it is reset, problems may occur if the switch settings do not agree with the amount of main memory in use. Switches 5 and 6 (Monitor and adapter type)-define the type of video card and monitor you are using and help the system address the adapter memory correctly. Set these switches using the following information: If you are using a composite (monochrome or color) or an RGB monitor with the color/graphics adapter, set switch 5 ON and switch 6 OFE (This is the factory setting.) If you are using a composite video monitor, and its resolution is poor, you may want to set switch 5 OFF and switch 6 ON. This selects 40-column text mode for your screen and improves the resolution. If you install a non-composite monochrome monitor and video card, set both switches off. A-4 Setting the DIP Switches

Switches 3
and
4 (Memory
size)–indicate how much
built-in memory is available. You only change these
switches if you install a memory card and you want to
use part of the optional memory instead of the built-in
main memory. The factory setting is switch 3 OFF;
switch 4 ON.
Because the system checks the amount of available
memory each time it is reset, problems may occur if
the switch settings do not agree with the amount of
main memory in use.
Switches 5 and 6
(Monitor and adapter
type)–define the
type of video card and monitor you are using and help
the system address the adapter memory correctly. Set
these switches using the following information:
If you are using a composite (monochrome or
color) or an RGB monitor with the color/graphics
adapter, set switch 5 ON and switch 6 OFE (This
is the factory setting.)
If you are using a composite video monitor, and its
resolution is poor, you may want to set switch 5
OFF and switch 6 ON. This selects 40-column text
mode for your screen and improves the resolution.
If you install a non-composite monochrome
monitor and video card, set both switches off.
