DOS 3.2 or later is required unless you go with someone else's disk driver. A 3.5 drive is no different from a 5.25 other than the size. Most 3.5 drives are 720k, organized as 2 surfaces with 80 tracks each, just like a Teac 55F or similar non-1.2meg 80trk drive. The latest Minix floppy driver (with my 720k mods, now in the distributed copy), will work fine on all 720k drives I've tried... including the Teac 55F 5.25 80trk, Sony 3.5's hung on an XT controller, and the 3.5's in laptops such as the Toshiba 1100+, Toshiba 3100, and Zenith 181 (that's all I've tried myself). You can also read/write 720k 5.25 floppies on an AT's 1.2meg drive, apparently with no ill effects. >Does DOS 3.2 work with Minix? Huh? From the poster on the pillar by my desk...
