Mine has problems as well. I know there are workarounds, but I'm not
experienced enough to do these. Joe: what error messages do you get? I get
the "hde: timeout waiting for dma" errors. After that I have to cold start
my PC to get it working. BTW, I have a PDC20265, but I think these are
probably almost identical (or at least the behaviour we are getting is
probably due to the same problem in the code).

I also suspect that maybe what kind of hard drive you have makes a
difference as well, because some people can get their Promise IDE to work
fine, while others can't. I have a Quantum Fireball Plus AS.

In case you didn't know, Andre Hedrick met with some dude from Promise
called Craig Lyons on Wednesday. I haven't heard of any news from the
meeting, but supposedly Craig was going to give Andre some API for the
Ultra/Fastrack line of chips. Hopefully it went down on Wednesday.
