Am > I wrong in my understanding that DMA is always desireable? It isn't desirable at FC4 installation time with certain combinations of DMA controllers/motherboards and certain CDROM drives. In my case it was an older Mitsumi drive. No combination of the recommended, non-standard boot parameters fixed my problem, so I just pulled-out the older CD-ROM drive, threw-in a newer DVD-ROM drive which had been in a different machine, and it installed perfectly. Hopefully you can do the same. In my case the non-system volumes are usually on separate disks so I can always just start-over or throw the old hard-drive into a different machine to get to my files. Suffice to say that this was by far the most difficult installation in the nine years I've been using linux. Of course the very same motherboard and CD-ROM drive had run two previous releases of RH and one earlier Fedora. I guess something got dropped or overlooked in the course of driver or Anaconda development but I don't know the details. Fedora's relatively new and there will be some bumps. You and I just got unlucky. Technology marches ever onward and sometimes someone gets trampled along the way. The Mitsumi drive was _many_ years old and I'm cheap. > Dave * Nick Geovanis | IT Computing Svcs | Northwestern Univ | n-geovanis@ | northwestern.edu +------------------->
