Re: SCSI CDROM

[Chris Hornbrook <chris f hornbrook noaa gov>]

Thanks for the reply.  I have the same SCSI controller and I the same line
(alias scsi_hostadapter aic7xxx) in my modules.conf file.  However it is not
getting loaded on boot.  When I manually loaded it
(modprobe aic7xxx) everything started working.  I can mount my cd and read
from it.  Any ideas why it isn't getting loaded on boot?

Thanks
