Hello everyone,

	I need a routine to check for the existence of a readable floppy
in either drive A: or B:, without getting the DOS message "Abort/Fail/Retry"
messing up the screen in graphics mode. I tried using int 13h, but when
that failed I remembered about having scanned that on the list ;-) And all
the int 21h routines come up with that message. Even trying to directly
program the floppy controller lead to no result. Since I know it can be
done, my question is: Does anyone how to do it?

	A possible side-effect of answering this question would be that
the window-oriented graphical user interface my friend and I are working
on comes one step closer to being released into the public domain...

	Any help apreciated, and, of course,
	many thanx to DJ and the others...

		Oliver
