Doesn't matter what your experience is.  Novell has acknowledged the problem
and you had to apply a modification to get Xenix to run.  Supposedly Novell
Netware runs just as well with the patch, but the problem is that it has to be
patched just for a DTK motherboard.  What other problems will one encounter? 
Will certain cards not work with it because of it being a bit off from the ISA
spec?

Since I'm the head of tech support where I work, I can make certain decisions
regarding what we will and will not support, and DTK products are HIGH on the
list.

Other problems I've had with DTK.  I put a guinine DTK floppy drive controller
in a 386SX machine and the video card wouldn't work.  I know it's not the
video card because of the fact that the same video card was used with the
floppy drive controller in my ancient 286.  Pull out the DTK floppy and the
display comes back.
 
To be fair, I tried the DTK floppy drive controller in another machine, sure
enough, it worked.  The 386SX motherboard had an Intel/Zymos chip set, nothing
unusual.

DTK products have given me nothing but problems and I certainly will not buy a
DTK product nor will I support them in the field.
