Hi all,

  I just got RedHat 3.0.3 (blah i needed it for cheap Metro-X ;)
  I am trying to my CD-ROM drive detected at boot up here is
  the info (as much info as possible follows ;):

  Creative 8x CD-ROM connected to SB32 i/f which supposedly
  (according to my DOS device driver) emulates primary slave

  Unit 0, Slave, ATAPI, I/O address 0x01f0 the driver says

  I tried forcing it with "linux hdb=cdrom" also hda for luck
  and it detects the CD-ROM as:

  hdb: CD820E.1v1078300, ATAPI, CD-ROM

  as the kernel boots up.  As my system boots up from reboot
  it doesn't detect ANY ide devices (I have SCSI hdd) so I
  guess the SB32 is doing something weird to make it look
  like a CD-ROM is on the slave of primary controller but
  Linux can't see what it's doing :) -- I've got no clue!

  Redhat sent me a cut+paste response which was less than
  useful telling me try things which I've already tried :-)
  i.e., I told them i tried "linux hdb=cdrom" and I told
  them the CD-ROM was on "hdb" - so they told me to try
  "linux hdb=cdrom" and switching the CD-ROM jumper to
  make it hdb - GLAD TO SEE THEY READ MY MESSAGE!

  BTW: using 2940.ker image for my SCSI card - I got the
  "updated" one from RedHat and put it on my boot disk
  and it proceeded to hang so I'm just using the standard
  one which detects my CD-ROM anyway but it can't be
  mounted.  i.e.,

  It says something like "Bad fs or superblock" when I
  try to mount the thing! :)

  Can anyone please help out?

Daniel.
