I am not a QNX programmer or a developer but I am involved with QNX.
Quickly, our company builds a medical instrument that has a computer
motherboard with an AMD 90 MHz CPU running QNX (I believe it is Ver 2)
on the hard drive and it has a floppy drive to upload new user software
as needed. We have a set of utilities on our Win 98 laptops that we can
run (using a DOS window and command line prompts) and create QNX
formatted disks; capture an image of a QNX disk that was created in the
medical instrument or create an image file on a DOS formatted disk that
can be read by the medical instrument. Everything was going great until
our IT department decided to replace our Win 98 laptops with Win 2000
laptops. Now, I can initialize a DOS disk, perform a CRC check of the
disk but I cannot write an image file to the disk (DOS or QNX format).
The utility (the filename is QDSK.exe; 111 kB) looks like it is a very
small program that allows ls, rd, md, wr, fr, fw, ini, crc, fcrc, and
query.
Our IT department understands Windows but they have no idea what this
QNX utility is doing and why it won’t work on a Win 2000 machine in the
command prompt window. Can anyone provide me some insight?
If you want to look at the files, I can zip and e-mail them if needed.
Sounds like the DOS program used special BIOS calls or privileged
instructions that “NT” based Windows OSs don’t allow you to use. Your
laptops need to run a DOS based OS (DOS, Win3.x, Win95, Win98, WinME).
My suggestion would be to go to a Win9x machine and make a boot floppy.
Then you can just boot into DOS and do your thing, even on systems with
Win2K.
