You should be fine with the large drives. > - Are (U)DMA modes supported on Alpha ? I really do not want to waste > CPU-cycles > processing loads of interrupts in PIO mode.

Well, the Contaq device has 2 IDE controllers, however if you look at the board you'll see that only one has been brought to a connector. So in effect you're limited to 2 devices. > - Any general recommendations about which drives *not* to use ? > > While asking funny questions anyway, here are two more not related to the > above topic: > > - Anybody ever tried using USB on the UP2000 ? Ummmm....I think I got it to see the controller, but that was a while ago. I do have it working on a UP1000 so the codes seems to work on Alpha. It's just a question of if the works properly with the Contaq controller. --rdp -- Rich Payne [EMAIL PROTECTED] www.alphalinux.org
