Hi, Steve:
According to the manual:
"If location D0000H is not available in your computer, the suggested
address is A0000H. If this address is not available, see the following
possibilities:"
Then it goes on to list addresses 8000H, 9000H, A0000H, B0000H, C0000H,
D0000H, E0000H, and F0000H as possible memory segments, along with why they
might _not_ work. It says Iluminit will warn you if E0000H conflicts with
BIOS ROM or transient data — is this what happens?
My reccomendation is to use the board in the illuminator mode with two 32k
buffers at the D0000H address. Even though you say it is impossible to do
on your machine, this is the way I've seen it work best most often, and
maybe a re-evaluation of priorities will bring you to try this
configuration.
I use the ADI's supplied by Matrox with much success. Also, the Windows 3.1
drivers and frame-grab software allows me to be extremely productive with
the board in Windows, as well as offering near true-color (depending on the
software dithering method, it can be almost as good as 24-bit!) 640×480
non-interlaced display.
As Gary often says, hardware conflicts are the worst! Somtimes one has to
make choices based on their personal priorities. Maybe QEMM could save the
day again by excluding and moving memory segments….
Hope this is helpful!
Alan
