I'm having a problem running DOS apps on Windows 3.0. When I
run a single DOS app, either as a window or full-screen, everything
is just fine. When I try to run a second application (command.com
for example), I get (in one of the dos windows) "memory allocation
error, can not load COMMAND.COM, system halted". The overall
windows performance becomes very sluggish at that point, and I
have to "terminate" both dos windows, and reboot (otherwise strange
things happen later, like steady beeping, etc).
Is there some trick to running multiple dos apps simultaneously? I
usually have tried running command.coms to give me "dos windows."
For reference, the configuration is as follows:
80386-DX/25 Mhz
8 mb 70ns 1MB chip DRAM
4 MB smartdrv
1 MB ramdrive
The motherboard has the Chips & Tech. chipset
The BIOS is 04/09/90 AMI
(shadowing is enabled)
ATI VGA Wonder w/512K and NEC Multisync II
running in "VGA mode" in windows.
Since I made this upgrade after finding that WIN3 didn't do what I wanted
(actual multi-tasking of DOS apps in (and running dos apps in windows)) on
my 286, I'd really like to find out what is happening here. (at least as
a temporary solution until I get UNIX installed).
Thanks in advance for any comments, advice, tips, suggestions, etc.

I have 10 MB RAM and 03/09/89 AMI BIOS. The main difference is I don't run smartdrv and ramdrive. I use PC-KWIK instead. And I am able to run multiple 4DOS windows in WIN 3 386 mode. The maximum I went to is 4 (I think). I tested simultaneous compilation in two of the 4DOS windows and at the same time running GIF file displaying cycle on a third full screen 4DOS window. So, may be smartdrv and ramdrive are screwing up. Regards, ## Life is fast enough as it is ........ Peter Lim. ## ....

I haven't tried 4dos, but the problem is gone anyway. I have heard about something called "hyperdrive" or something like that. Have you tried that one? Is your m/b the Soyo one, or is it "the same" in that it has the ami bios and c&t chipset?
