			fakedisk 0.99 beta
		(c) 1996 by MCA Software Group

this program reads disk image file into XMS and hooks int 13h
(functions AH = 2 (read sector) and AH = 3 (write sector))
emulating one of the physical floppy drives

idea by Alex Bokov (the author of DDI - read/write .ddi images)

to use fakedisk you should have
	- at least one physical floppy disk drive
        - XMS driver 2.0+
        - amount of available extended memory

disk images can be changed on the fly

this version can't update disk image file
this feature will be added soon

fakedisk will not work in OS/2 DOS box because int 13h is not used in
OS/2 DOS box disk i/o operations
programs that use int 13h will work correctly (i.e. will read emulated
disk instead of real physical disk)

currently tested on .ddi, .xdf (eXtended Density Format by Roger Ivey) and
.dsk (sector by sector) disk images

used Don Nelson's convertion routines from Crynwr packet drivers package
