Are you running an 001, then? I bought my Digidesign AudioMedia III card
(2-in, 2-out, analog or digital) just a few months before the 001 was
announced. Needless to say, it was rather frustrating that there was no
upgrade path. My studio partner and I were also unfortunate enough to
purchase our MIX plus system just shortly before Pro Tools HD was announced.

We're still at 5.1.3. We'd have to upgrade all of our plug-ins to MacOS X
versions if we switched to PT6 :(

This sounds like a great solution. In a pinch, it would also be away of
getting files between here and the studio. I'll definitely have to look

I'm confused by what you quoted. XF86Config is my X configuration. .config
is my kernel configuration.

Thanks, I'll try your technique as soon as I can make the time.

Yup - this irks me to no end, but I wasn't able to fix it in my initial

This was the first thing I tried. Same IRQ asignments even after the
change. I'd look up the BIOS settings so I could better explain the
problem, but my Linux box is building a new kernel right now.

Come to think of it, I'm not sure whether I've even looked for the drive
under Linux since I plugged it in. It might actually be there. I suppose
I'd have to build the controller drivers in order to access the drive at any
reasonable speed, however.
