Hi there Killen. Good to have you on board, and I hope we can sort out your BP6!
I have had a bad flash on my BP6 before. I brought it back from the dead by using an old ISA video card. Using one of these cards, you can get the BP6 to just about function with a display and floppy drive. From there you should be able to flash with the appropriate boot floppy and BIOS files.
FYI, the BIOS chip on my BP6 reads:
ABit may be able to supply you with another chip if you contact them.
On the other hand, somebody here might have a non-functioning BP6 that could be a BIOS chip donor! Let us know which part of the world you are in.
Welcome to our club, and let us know how you get on!
