According to my memory, we had more than 600k free under MS-DOS on our Amstrad PC1640, as reported by the mem command.
Now, I can't seem to get more than 561k.
The usual tricks of using himem.sys and dos=high,umb does not work for me , as himem reports "requires 80x86", and .. "cannot load dos HIGH". I have an 8086-2 CPU.
Output from mem says 0 -zero- in all memory areas, other than conventional. What remains is the traditional 640k minus what DOS and a default install of MS-DOS (setver and more) uses.
Is there a way of loading DOS and other TSRs in an area above the 640k on this machine?
Am I wrong when I recall having 600k available under MS-DOS 6.22? Was there some memory upgrade available for PC1640 that gave us a bit more ram? I think we had some EMS ram reported in the mem command output.
