I had a similar problem with an 8000 with A02. It would boot to the BIOS opening screen and showed all drives present, but DOS showed no bootable devices and it would not boot the Harddrive like yours. The board I have has a socketed BIOS chip, so I popped it out with a chip Puller and substituted a Spare BIOS Chip with A23. Normal operation resulted across the board. So I put in a BIOS Flash Floppy and booted the board to the screen where you answer yes to flash the BIOS with A23. I stopped without powering down, and removed the good BIOS Chip with heavy wooden toothpicks, substituted the corrupt chip and pressed "Y". A normal flash to A23 resulted and normal ops from that chip thereafter. I did this to another chip with the same symptoms and version with the same results.
Whether this is possible with your Board/Chip would depend on whether the chip is socketed or soldered.
Thank you for your excellent advice. I was able to flash to A23, and IT ALL WORKS NOW! I had not raised to A23 because of advice on this board to avoid unless necessary. It was necessary, as you suggested. BTW, I am dazzled by leduke30's ingenuity. Fortunately, I did not need to trade out chips, but the technique is very interesting, and should help other readers. Again, Thanks all. Olivia
