I need to run several DOS tasks silmultaneously on an AT equipped with an Intel Inboard 386 with 3MB memory. This should be possible running what Intel calls "virtual 8086 mode", but I know almost nothing about the control software necessary to do so. Desqview and PC-MOS are the only two candidates I know of. Are there others? I am particularly interested in how well the control software separates the individual 8086 areas - for example, does a crash in one program bring the entire show down? At some point, I will need to share some files between the different areas, so if anyone has insight into any pitfalls, I would appreciate the opportunity to learn from your mistakes. I realize that the above paragraph has many ill-posed questions, but I am truly a babe in the woods on this one. Partial or full replies would be greatly appreciated.

It is a Real-Time Operating system that runs on '286 machines (should run on a '386) in protected mode. It permits running DOS in real mode (if you have enough memory). It also has some very powerful networking capabilities, using Arcnet. Quantam advertises monthly in Byte, or contact me via e-mail for more details. =#=#=#=#=#=#=#=#=#=#=#=#=#=#=#=#=#=#=#=#=#=#=#=#=#=#=#=#=#=#=#=#=#=#=#=#=#=#=# Dick Gardner -- Eastman Kodak Co.

Are there others? Desqview works very well on a 386, using the package which emulates LIM memory. I believe it's called QEMM, but I don't have a copy at work. It is not totally indestructable, but it works very well for programs which are even reasonably well behaved. It has a windowed environment, and runs things like Procomm in the background. You will want to read the section on tuning carefully, but it's not all that complex to install. MicroPort sells V/386 and DOSmerge/386 which allow running multiple DOS sessions completely in protected mode. I saw this in January at UNIFORUM, along with a version of X-windows, but I don't believe it's shipping. I tried to do a comparison of V/386 and Xenix/386 at work, and was promised a Beta copy, but I never got it. If you can actually get a copy, V/386 would seem to be a good choice, since it's UNIX based and will give you additional control option. Bell is supposedly selling the Interactive port for $399, but I don't believe they're selling the DOS support just yet. -- bill davidsen (wedu@ge-crd.arpa) {uunet | philabs | seismo}!steinmetz!crdos1!davidsen "Stupidity, like virtue, is its own reward" -me
