[comp.sys.ibm.pc] Vanilla MS-DOS 3.3 on Leading Edge Model D?

wales@valeria.cs.ucla.edu (01/19/89)

My church group has a Leading Edge Model D, with Phoenix BIOS version
2.13.  This system was bought in 1986 and came with Leading Edge's
MS-DOS 3.1.

The only incompatibility I am aware of between the LE Model D and a
"true blue" IBM PC is that the Leading Edge has an on-board clock/
calendar (and, of course, no ROM BASIC).  The MS-DOS 3.1 that came with
the system has a CLKDVR.SYS driver for clock initialization.

My question is:  Will the generic "Packaged Product" MS-DOS 3.3 (the
version made by Microsoft and not modified by any OEM) work properly on
a Leading Edge Model D?  Or are there other weirdnesses in this machine
(aside from the clock/calendar -- and I assume I can just hang onto the
CLKDVR.SYS from the DOS 3.1) which require a version of 3.3 that has
been specially modified in some way by Leading Edge?
