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?? -Charlie
