Forgive me if this has already been answered (it doesn't appear that it has been, because a search for "floppy" returns this as the most relevent and newest modified thread)...
Wild Pencil, Did you actually get this working in the BIOS? I bought a BIOS from you a few months ago, would it already be supported in here? I see it listed in the BIOS Setup program, but everything I've read so far makes it sound like the BIOS still doesn't let it work.
Honestly, the reason I want it is so I can hook up a 5.25in floppy drive to my I-Opener whenever I need to use those ancient disks (happens relatively often with all the old computers in the family, and the junk that I always get hold of). I intend on putting a 34pin header on the case (or possibly a DB-35 on the case, haven't decided) to which I can connect whatever floppy drive(s) I need at the time. The thing that brought this idea on was that I want to test my new Serial I/O adapter, and I wanted to use a serial mouse to do it. However, the only serial mouse DOS drivers I seem to have are on a 5.25in floppy. I know I could probably download them somewhere, but this is also for the hack value in addition to being useful (to me) for other projects.
I'm asking now because it's been a long time since anyone talked about the floppy hack, and it was still left in the air. I don't want to solder all those tiny pads and cut holes in the case and spend so much time on this if it's not going to work and noone is interested in making it work anymore!
WildPencil, your contributions here have been more than amazing. Thanks so much! I hope you haven't gotten burnt out on the I-Opener ;)
