Keywords: qemm Message-ID: Date: 17 Jun 91 02:15:31 GMT Sender: usenet@convex.com (news access account) Distribution: usa Organization: CONVEX Computer Corporation, Richardson, Tx., USA Lines: 18 Nntp-Posting-Host: dhostwo.convex.com Every so often, when running qemm and any program which makes extensive use of the extended/expanded memory it provides, my pc will get an interrupt 13 (general exception), usually in the middle of running a command. Most recently, it likes to occur when running Borland c++'s integrated environment and attempting to compile something. I have seen the problem in qemm 4.2 - the current 5.1x. The problem would appear to be qemm taking a trap because the program attempted to reference a word (or double word) at an address that would require some of the word to be fetched from the top of the segment and the rest from the bottom of the segment (eg, read a word at 0xffff in a 64k segment). The PC is a Wells American 386-25 running qemm 5.1 and msdos 3.3. A friend of mine says he has had similar problems on his PC (also a 386-25, but made by leading technologies, I think). Anyone know what the problem is, and how to fix it? it really gets annoying when you have to reboot the machine several times an hour... Thanks, Roger
