- A common problem. Many 286/386/486 chipsets can't deal with mixed 8-bit and
- 16-bit RAM/ROM within each of the 128Kb high segments (A000-BFFF, C000-DFFF,
- E000-FFFF). Since your video board ROM is at C000 and the only addresses for
- the Adaptec are in the C/D range, you're stuck. See if you can configure your
- video board in 8-bit mode (there is usually a jumper). If that doesn't work,
- move it to an 8-bit slot (making sure the extra connector doeesn't short out
- anything nearby when it's hanging loose).
