I read that 4DOS is a command.com replacement and only occupies 5K of conventional memory when you load other applications over it. Sounds too good to be true. What I want to do is replace command.com which I load before I run DesqView. Will 4DOS do this and save me memory, yet still support dos system calls for applications? I tried to obtain 4DOS from SIMTEL20 via a mail message to listserv@vm.ecs.rpi.edu (to answer these questions for myself), but the package was not found (although it is listing in the latet SIMTEL20 directory). Any other locations for picking up 4DOS? Thanks, --- glenn

Sounds >too good to be true. No it's not. Actually, 4DOS only takes .3K of conventional memory in my 386 using QEMM. The rest lives in expanded memory. >I tried to obtain 4DOS from SIMTEL20 via a mail message to >listserv@vm.ecs.rpi.edu (to answer these questions for myself), but >the package was not found (although it is listing in the latet >SIMTEL20 directory). Any other locations for picking up 4DOS? A new version was posted recently - 3.03. I don't remember all the file names, but I think they're in PD1:<MSDOS.4DOS> on SIMTEL20 as: 4DOS303P.ZIP programs 4DOS303D.ZIP documentation I just loaded the update to version 3.02a, so I didn't need the whole kit, and thus don't quite remember the names. You might try looking through the last week's worth of articles in comp.binaries.ibm.pc.d. - Jim (who feels *naked* without 4DOS!) =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= "The opinions expressed here in no way represent the views of Digital Equipment Corporation."

Sounds >too good to be true. Not really, since 4DOS occupies ~4K of resident memory while COMMAND.COM occupies ~5K (unless you have XMS, in which case you can decrease the resident size of 4DOS further). 4DOS is *not* a replacement for DOS-- just a replacement for the command line interpreter (and an excellent replacement at that). -- +==========================================================================+ | Noam Mendelson ..!ucbvax!web!c60b-1eq | "I haven't lost my mind, | | c60b-1eq@web.Berkeley.EDU | it's backed up on tape | | University of California at Berkeley | somewhere." |

Sounds > too good to be true. I renamed 4DOS.COM to command.com and the kernel is only 256 bytes when it is swapped out. With a CGA monitor and a LOT of things loaded in high memory, I have 689K free for DOS. > What I want to do is replace command.com which I load before I run > DesqView.

I do this on a 386/25 with 8 megs of RAM, running a mail/news site with a full feed and cron as a background task. > SIMTEL20 directory). Any other locations for picking up 4DOS? You can download it from here. It's in /public/4dos. Or I can email it to you. -- halcyon!ralphs@seattleu.edu The 23:00 News and Mail Service - +1 206 292 9048 - Seattle, WA USA +++ A Waffle Iron, Model 1.64 +++
