Hi everyone,

I am running my program compiled with djgpp from a floppy. The computer
does have hard disks attached but they are usually corrupt. I am
finding the following error on starting up my program:

Error reading from drive C:
Abort, Retry, Ignore?

Now, why would the program try to read from C, when the floppy is in A?
I believe that it is not my program but rather the CWSDPMI stub which
is trying to read from the hard drive(I think it tries to verify that
the drive signature is 0x55AA). And to verify this, I run the same
program with different healthy drives, and I do not get this error.

How do I prevent DPMI from accessing the hard drive? I do not need any
paging file or virtual memory. I tried to execute cwsparam.exe with ""
(blank) as the paging file, as indicated in the cwsdpmi docs, But No
Luck.

Please let me know your thoughts on this error and how can I remove it.
Any help is appreciated.

Thanks,
Ahmad
