That the Digital Research that made DR-DOS was the same DRI that made CP/M. I read an article describing the history of CP/M and DR-DOS, and
now I want to run a DR-DOS VM for old time's sake.
I was one of those outliers that didn't run Windows in the early 90s. I didn't have a lot of horsepower at home - when I had a local bus 486/50 with 16 MB of RAM at work, I had a 386SX/16 with 3 mb of RAM at home.
I ran DR-DOS and SuperStor (my co-sysop worked for Addstor and got comp copies of each) and GEOWorks Ensemble. With DR-DOS' task switcher, it
was a pretty cool setup.
Outside of Geoworks, it was all Borland Sidekick, Qedit and Telix.
My first PC was a hand-me-down 286-12 in 1992, and then I got it
upgraded to a 386SX-16 in 1993. At the time I didn't know of GeoWorks
On my DOSBox-X setup, using VIDRAM ON makes DESQview unstable. It runs at first, but if I open and close a couple DOS windows then it crashes. I think the use of VIDRAM (or rather, me not using it) is making the big difference in memory availability. I wonder what is causing the instability on my DOSBox-X setup and if it could be solved with a configuration change. Or is it as simple as changing my DESQview display adaptor settings? (currently VGA, with 'do you want text & graphics displayed at the same time' set to Yes and synchronized access set to No)
It has been a long time since I used QEMM and DesqView, but I seem to remember DesqView saying I'd need to set up QEMM in order for it to use some features related to multi-tasking, or maybe just for more optimal behavior. I don't remember for sure.
I think I have heard that before, though I haven't experienced/verified it myself.
File locking is working for files on the network share, if I have a file open and try to also open it in a share-aware program, it is prevented from opening. I'm not sure if there's better, more specific, tests to do, but at least I haven't experienced any data corruption on the BBS, so I think it's OK.

I'm sure you're right for anything pre DOS 5. After that I think you could get away with EMM386. Locally some reported better results with one or the other. Never found much difference myself. Also aside from exploratory installations I never really used DV.
Yeah, even with MS-DOS 6 and above, I seem to remember getting a bit better results optimizing memory with QEMM compared to EMM386 and MS-DOS's memmaker.
DESQview in DOSBOX, eh? Are you running a DOS image inside of it? If
memory serves, DESQView needed QEMM to run.
What options are you loading QEMM with? I'm not running DV, I use a VM
for each node/task, but I've got 593k conventional free. After network

Most of the memory usage is the network drivers, with none of the
Microsoft Network Client stuff in autoexec.bat, I can boot with 633K
free. Maybe it can be optimized further, but this is what qemm OPTIMIZE gave me.
Do you happen to know what the R: parameter for QEMM386.SYS is? I
haven't found a description in the tech nodes included with QEMM yet,
but I have noticed that when I let optimize run it adds an R:1 or R:2 parameter.

You need to run through mft and get the optimization tuned. There is a analyses section, that lets you list memory to "include" on your qemm386 line..

Aside from having a general look at what was loading where, and seeing
what conventional memory was free, I don't recall using Manifest for anything much else. Might not have fully understood it at the time.
Back then optimize pretty much got it right, occasional footling around trying to coerce another driver/tsr high.
My current configuration being DOS 6.22 in Virtual Box steadfastly
refuses to load anything high. Optimize can optimise until the cows have come home and gone to pasture again. It'll add in all its
recommendations and on restart nothing will load high.
