Hello,
When installing plan9 from the boot CD, I ran into a disturbing problem
: during the mountdisk phase, I was totally unable to select the CD-ROM
as distribution disk. /dev/sdD0/data was listed in scanned disks, but
the only one to be detected was /dev/sdC0/fossil.
I remembered then (from past experiences on linux) that my CD drive
didn't like DMA very much. I restarted the whole installation process,
without enabling DMA for IDE drives, and eventually /dev/sdD0/data was
detected, and the install could go on, although quite slowly as one can
expect.
It looks like that the install isn't able to handle DMA failures, or at
least partial failures for one of the IDE drives (DMA just works fine
with my hard drive). Although it's the very hardware fault, it would be
safer to fall back to "no-DMA" if some error occurs during its
initialization.
Regards,
Vincent Pit
