DOSEMU 0.98.6 floppy problems/lockups etc...

[Steffen Winterfeldt]

As this has been asked quite frequently during the last days:

If you have any floppy related problems (eg. dosemu locks up while
accessing it or you cannot boot from it or whatever), please
apply the patch below (will be integrated in 0.98.7).

Note that the patch I posted in the thread
"floppy A: B:, vbootfloppy and 0.98.6"
was broken; use this one instead.


Bye,

Steffen
