I've got floppy problems in OS/2 and Win98 as well. Booting the
installation floppies and a win98 boot floppy both works fine, but from a
fully installed version of OS/2 and Win98 installed on disk I cannot
access the floppies at all.
The difference: booting probably goes through int13 on all systems, i.e.
through the bios, but once OS/2 and Win98 later access floppies by
programm the fdc directly. So maybe there's a bug in that part of the
emulation.
