Increasing dos program compatibility

[Bruce Musgrove]

My boss has a dos based Data collection program that collects data through a
propietary board on the computer. The program works under in win2k, but we
have intermittent regular dropouts in the data gathering, as if the dos box
was suspended while win2k did something elese and then came back to the dos
box.

We reinstalled win2k in a basic configuration and no other programs except
our data collection program, and had the same results... SO.... can i
somehow increase the priority of the dos box so win2k will devote all of its
time to this box when we run the program?

You could start the command window with AboveNormal, or even RealTime
priority.

You can use start.exe to set priority when initiating the program.
I suggest that you be careful about using "realtime" priority as
it may starve essential OS threads and processes of needed CPU time.

If your program and peripheral both function in DOS, and this is the only
operation the computer performs (which I'm just assuming) then would it not
be easier to simply load DOS on the machine as the operating system?

Or, you can keep the W2K machine, buy Virtual PC for Windows, and load DOS
into a Virtual PC VM to natively run the DOS program inside the virtual
machine.
