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.
