    I put the magazine on the net.  Unfortunately I've tried the DMA
  stuff out too (the most interesting thing in the mag) and though I
  didn't put more than a couple hours into it, I didn't get it to work
    Does anyone out there have some good DMA code for the PC ....

This is my signature.  There are many like it but this one is mine.
 ... if you don't get it ... don't ask.

 Fast memory moves on PCs
I did some code a while back which does (non-DMA) memory moves on PC's
in arbitrary quantities (not limited to just under 64K like the libraries
of a certain compiler I use).  I never needed it in the end, but if
anyone's interested I could post it handles moves of >1 segment
and move backwards or forwards to correct problems with overlapping
memory blocks (and on the negative side its probably somewhat buggy


                     (In order of decreasing reliability)
  Something large, scaly, and with fangs a foot long lives between <yoursite>
and <mysite>.  Every now and then it kills and eats messages.  If you
receive a reply within a week, try resending...
