M057 12/18/90 SMR	MSDISK.ASM	Updating SDSB properly on SetOwner call
			MSDIOCTL.ASM

M058 1/2/91   SR	Msbio1.asm	Bug #4925. The CMS floppy driver
					assumes 70:b4 to be the address of
					the old int 13h handler save address
					and patched it with their address.
					This was true in DOS 4.01. Juggled
 					stuff to get this pointer at 70:b4.

M059 01/10/91 SMR	SYSCONF.ASM	Treat tick rollover byte as a count
			MSBIO1.ASM	instead of flag. However added a /t

					ROM Int13 patch.

M063 01/29/91 SMR	SYSCONF.ASM	B#4984. Added SWITCHES=/W to suppress
					loading of Wina20.386 from the boot
					drive.

M064 01/29/91 SMR	MSBIO1.ASM	B#5070. Made changes NOT to preserve
					A20 status across INT 13 calls &
					Ensured A20 is ON before calling BIOS
					CODE in HMA.

M065 02/05/91 CAS	msinit.asm	B#4945, COMPAQ buggy ROM check changed

M066 02/12/91 SMR	MSDIOCTL.ASM	B#5833. Modification M060 was required
					only for Toshiba machines and the
					problem on Toshiba machines can be
					solved by the 'setmedia' driver. So
					the retry for ah=18 call is not
					required. Also because of the retry &
					disk reset, format becomes slow on
					IBM external floppy disk drives which
					does not support the set_media_type
					call.

M067 02/25/91 HKN	sysinit1.asm	Set up the environment ptr to point to NULL when calling exec for
					install= command.

M068 03/07/91 SMR	MSINIT.ASM	B#6271. Added missed out RPL support.

M069 03/08/91 MD        SYSINIT1.ASM    Bug 6327.  Closing NMI window.

M070 06/03/91 MD        MSBIO.SKL       New message added for POWER.EXE.

M092 10/18/91 NSM	POWER.ASM	(Bug#: 2814,2832, & 2862)
			POWER.INC	Change CLOCK again. We don't maintain

					Tick Count. But we do maintain daycount
					;We don't increment when a rollover
