I am currently experiencing an *interesting* thing.
When I boot the below system under MS-DOS 3.3 the A20 defaults to disabled (as you would expect it should with no HIMEM.SYS loaded). BUT when the exact system is booted on MS-DOS 5.0 the A20 is defaulting to enabled and I am unable to disable it.
Has anyone else encountered this problem??
Anyone got any ideas on how to disable the A20.?? A piece of software I have
requires the A20 be disabled when it initilizes the keyboard on installation.

5MB DRAM
QUADTEL BIOS and KEYBOARD BIOS.
The boot disks I am using only contain IO.SYS/MSDOS.SYS and COMMAND.COM they are nice clean simple boot disks.
