Help needed to read IBM 1M formated floppy on something modern.

Other solutions are bound to be available, YMMV, caveat emptor etc :) -- Win 98, and 2000 at least don't care about the capacity of the "a" drive, I've had 1.2 MB drives on them just fine, I have yet to try with win XP or 2003. any issues with win 98 and 2000 not being able to read/write a 1.2mb drive as the 1st drive in the chain lie in the motherboard and bios. Some of the newer ASUS and Supermicro boards will let you assign a 2nd drive but you can't read ad write to it :( been bit by that one a couple times now. It turned out that the 2nd drive select line wasn't brought out of the silicon to the motherboard in the super-IO chips they were using :(
