I've had the same problem with an Panasonic SCSI-II drive connected to an
Adaptec 2910b controller. The way I was able to get the installation routine
to find the cdrom was to disable the internal cache, the external cache... ALL
speed enhancing options in the BIOS.
The only rational explanation I could come up with is that the Adaptec
driver, on some machines, does NOT wait "15 seconds for the SCSI devices to
settle", and therefore assumes that there are no SCSI devices on the system
before the poor cdrom has a chance to initialise.
Maybe there is some problem with the way how the driver determines how
long is 15 seconds, at least on my system anyway.
You could try disabling some of the PCI options in your BIOS first ( such
as PCI Burst). Only as a last resort did I disable the caches, because then
the install took ten times as long. You can always reenable ALL the options
after installation. My system works like a charm now.
Oh, and by the way, hit Scroll Lock after it does the driver check and use
PgUP-PageDn to see those messages that scrolled by too quickly.
