I am having trouble installing QEMM 9.0. My original copy is on 5.25" floppies. I copied the files onto 3.5" disks, but when I insert disk 1 and type "A:\INSTALL" QEMM reports an installation error "You must insert the QEMM diskette in your drive". Do the disks need to have the correct name/label? If so what? My 5.25" drive stopped working years ago so I can't install from the originalst, or make new copies.

Probably - as in 'Disk1"... 'Disk4" - try the label command Regardless QEMM9 (aka QEMM97): QEMM97 runs under DOS, Windows 3.1, Windows 3.11 and Windows 95. Memory requirements are 2 MB for DOS, 8 MB for Windows 3.x and 16MB for Windows 95 Your 1Meg machine isn't going to cut it Science is built up with facts, as a house is with stones. But a collection of facts is not more a science than a heap of stones is a home

One of my recent "25 cent treasures" is Quarterdeck's 1989 DesQview 386 that comes with QEMM386 and a memory mapper called MANIFEST. I skimmed through the manuals after seeing your post. The good news: QEMM386, an older version of QEMM97, appears to work on 1MB systems, though I suspect that it is limited by your computer not having memory over 1MB. The bad news: Some 386s, notably many Compaq 386 models, used "shadow" or "Top" memory. This 384K is set up in a non-standardard way and is not accessible to QEMM. Looking at the memory map in the manual - different for 386s - here are some unused ranges: 720-736K 752-768K 848-896K Also some you may not need on your Compaq portable (with CGA?) 640-704K EGA and VGA 704-720K Monochrome 768-784K EGA ROM 784-848K LIM Data Area- may be usable by expanded memory manager (but don't know if this is restricted by Compaq).

Sure - you can extend conventional memory on a CGA machine well past 640K by mapping contiguous memory from the A000 region - the downside is you'd be restricted to text mode only, as those addresses are normally reserved for graphics I believe QEMM includes the VIDRAM utility to simplify this Still, you can only do so much with so little Science is built up with facts, as a house is with stones.

"...I have managed to increase the largest executable size considerably by adding I=A000-AFFF to Emm386. This is normally part of the VGA frame buffer, but since I only have CGA this range is unused. I can load most of the drivers into this area now which frees a chunk of base RAM.", OP said in a recent thread. Of course, he didn't say if he was down to text only. The CGA block from 736-752K and the EGA/VA block from 640-704K appear mutually exclusive in use so that if a 386 PC has only a CGA display built in, it will have no use for the EGA/VGA block. Only OP can tell us for sure. funnyhand, I read your manual. Nice computer! So, can you see graphics?

Doesn't have to say - that's just how it works The effect you get from VIDRAM is similar to the effect you get when you load DOS's EMM386.exe driver with an I=A000-AFFF switch... The drawback to using VIDRAM is that you must refrain from using programs that switch to graphics mode (from DOS6 Memory management) With a CGA you can use I=A000-B7FF I=BC00-BFFF and gain another 112K, but it's a tradeoff for graphics mode - if VIDRAM is used instead, you can enable or disable as needed Science is built up with facts, as a house is with stones.

Interesting, jboy. I wonder why CGA graphics would use the space reserved for EGA/VGA. funnyhand, try this: 1. Find QEMM.SYS on your disks or from Wiki 2. Place it in your C:\DOS directory 3. In CONFIG.SYS, REM out all references to HIMEM.SYS and EMM386.EXE, i.e., don't run them 4. Add DEVICE=QEMM.SYS to CONFIG.SYS 5. Reboot 6. Run MEM to see how much available conventional memory you have. Should at least be as much as you had before? Let us know. This way you don't have the various tools that come with QEMM, but you have the main memory manager which is supposed to work without any help (like include statements) with 386 systems.
