[BUG] Floppy drive formatting issues

[teppic]

I'm having issues formatting floppies on some machines when trying to format a 1.44M image (tried in MS DOS 3.3 and 6.22 with nothing loaded).

Configuration is set to a 1.44M drive and the BIOS is set to 1.44M also.

EDIT: I tried a couple more machines and it looks like it might affect all AMI BIOS machines.

Examples with MS-DOS 6.22 on a 486:




Example with MS-DOS 3.30 on a 286:



Another 286 machine, same floppy image, same settings, same OS image, but works.



Similarly, the Award SiS 486 machine with identical settings seem to be fine too.
