I now have more questions about DesqView and where my memory is going. Currently, our Tandy 4000 has 4 meg, with 2 meg as expanded memory (this set only because the new R:BASE can use it, but soon will be extended). Now, when I do a QEMM, there is only 1744k of expanded memory. Where did 280k go? I have tried running XDV with 3 meg of extended, but I need 520k to open R:BASE and I cannot under XDV. The only problem now is swapping occurs on DISK instead of memory! No what?!?!?! -bryon lape-

On some of the TANDY 4000s the memory between 640K and 1Meg is unaccessible, or at least that is what I've been led to believe. Perhaps QEMM can't find it?

It's not QEMM that can't find it. On a lot of computers, the extra 384K ram is used to shadow the ROM (hence the name 'shadow ram'). It is not accessable. On some computers, you can set the extra 384K as extended memory in which QEMM will have no trouble finding it. And if your computer has the Chips and Technologies chipset, QEMM can access most of the 384K even if it is not normally accessable. ----------------------------------------------------------------------------- | Sam Shim | "I didn't do it... | | EECS Departmental Computing Organization | It wasn't me... | | University of Michigan | Nobody saw me do it... | | Ann Arbor, MI 48109 | Nobody can prove a thing..." | | internet: shim@eecs.umich.edu | - Bart Simpson | -----------------------------------------------------------------------------
