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.
