I do that too, using QEMM (Quarterdeck Extended Memory Manager). How-
ever, I had this problem long before I started to use the 386 memory
mapping features (at least I'm 98.5% certain about this). ON the
other hand it sounds interesting - those re-mapped 64k, above 640k,
is where the memory resident copy of COMMAND.COM will be. But the
fact that the error is 'cannot find it' indicates it is not found
*on the disk*. Not finding it in memory is normal, and causes the
re-load from disk.
