- The only solution I know of is to buy a floppy controller with a BIOS on
- it. I bought one from JDR Micro Devices, that seemed to work well - however
- the reason I bought it was because it supported up to 4 floppies, not because
- of the bios.
-
- I also tried one other brand (I don't remember what), but it didn't work, so
- if you can, get the card from a place with a good return policy.
