Other Cards in your System
Other cards in your computer may be causing a memory
conflict with the CompuScope card(s). To check whether this
is the case, try running a “bare-bones” system:
Remove all other boards from your computer, leaving only the
motherboard, the video card and the hard disk controller. If
you still can’t get the board to work, try it in another computer.
This may help identify the problem.
Then insert all other boards in the computer, one at a time,
and check for any conflicts using GSINST.
Advanced CMOS Settings
Some computers use the Upper Memory Blocks as Shadow
Memory to speed up the system by copying data from slow
ROM devices to fast RAM. This can cause a memory conflict
if the default CompuScope address is occupied by shadow
memory.
For example, Gateway Pentium computers have an option
called DISABLE SHADOW MEMORY SIZE in the advanced
CMOS settings. The default selection for this option is
DISABLED, meaning that all upper memory blocks are to be
used for shadow memory. Change this setting to 16K and
then set the next option, DISABLE SHADOW MEMORY BASE
ADDRESS, to D000. When you save these settings to CMOS
and reboot, the system will not use the area D000 to D400.
While it is impossible to list all the CMOS options used, it can
help to disable everything that is not essential to running a
“bare-bones” system, including cache memories, Fast A20
Gate Enable, Shadow RAMs, Video Shadow RAMs, etc. If you
are then able to run the card(s) without any problems, then
reactivate each feature one by one and test for normal
operation of the CompuScope. You will eventually find the
setting(s) causing the problem. If none of these steps resolves
the Memory Conflict, contact Gage for assistance.
