Gayle,
If you only have one hard drive, why do you have two hard
drives enabled in the CMOS setup? Oh, nevermind, I see you have them
both set as NONE. I assume the hardcard is scsi, then, and not IDE.
That may be the source of the problem. Try excluding that memory
segment I mentioned in the previous message. The block between
C000-CFFF is probably where the hard card's controller lives. That
block is typically where most scsi controllers ROMs are placed. When
you say you are using the A: drive connection on the BB, do you mean
you are using an internal PC floppy drive? If you are using the BB
floppy controller, then be sure to disable the floppy drive
controller on the multi-i/o card. The default for this is that the
second set of jumpers is OPEN to disable the floppy controller on the
multi-i/o card. You should also be careful about the serial and
parallel port setups. The second serial port should be configured for
COM3. This is done by jumpering the seventh pair of jumpers on JP4
and removing the jumper on the sixth pair. You should also set JP5 to
use IRQ 5 for the parallel port and NOT IRQ 7 which can cause a
conflict. JP4 should be set up:
o o o o o-o o-o o o o o o-o o-o o o
JP5 should be set up:
o o-o
and JP6 as:
o-o o-o
These settings should disable the floppy and IDE controllers on the multi-i/o
card, switch the parallel port onto IRQ 5, and put the serial ports on IRQs 4
and 10.
