Sorry I can't help with the original intent of this thread. I've got enough 360Ks and 1.2Ms kicking around that if I find one that doesn't cooperate, I pitch it and grab another. If the Toshiba won't work, and the BIOS supports the format, get another drive. They're easy to find, and inexpensive. I got "refreshed" at work, and the new peecee (Compaq Evo) won't recognize my 360K. I NEED that 360K to transfer stuff to my TI-99/4A here. The BIOS doesn't appear to handle anything other than 1.44MB drives (A and B; why would you ever want two 1.44MB?). Is this just a stupid Compaq thing, or is it becoming common among BIOS and motherboard producers to drop support for older formats? I didn't think about using a peripheral card with a floppy controller; I've got a few kicking around in my "lab" at home. With my luck, this Evo won't have ISA slots, though. I'll bet there aren't any PCI cards with floppy controllers... But even if you put a controller that can handle 5.25" drives, doesn't the BIOS still need to be set to 360K? If it isn't there, it isn't there, seems to me. Pardon my peecee-ignorance, it is NOT my favorite platform.
