I won't answer for MS-DOS, but I'm now adapting my old 1.1 stwini.c that used to enable me to work with "any format" disks, with any number of tracks, sectors and sides on a ST. Given my hardware (I've got a cheap drive), I can support as much as 810K disks, with 81 tracks, 10 sectors, 2 sides (The Amiga use 80 tracks, 11 sectors on 2 sides). With the new driver, dd0 and dd1 vanish, the driver adapts itself to the disk type. I'm working on the format stuff, which was introduced since 1.1 Anyway, when you control the hardware, there's no reason not to push it to its limits - provided that everybody else will be able to do the same (I hate those software editors who use track 81 for protection scheme: I CANT ACCESS track above 80!!!).
