[net.micro] Clone/CPCDOS

CSTROM@SIMTEL20.ARPA (09/03/85)

I have a weird problem with Concurrent PCDOS version 4.1 running on an
IBM XT clone. Perhaps someone has run across this?
I cannot operate if all 640K of ram is allowed in the system; I have
to use SETUP to allocate a minimum of 64K as an M-Drive, and even
then, the ram disk is unuseable. The operating system is flawless as
long as the system is 576Kb or less.
The memory is _not_ defective, and the system has run every MSDOS
program I have tried thus far.

Any brilliant ideas??
