none /dev/pts devpts mode=0620 0 0
/dev/hdb6 /home ext3 defaults 1 2
none /mnt/cdrom supermount dev=/dev/hdc,fs=auto,ro,--,user,iocharset=iso8859-1,codepage=850,umask=0 0 0

Please tell me that the CD in the burner is not a blank one? Have you tried mounting the device exclusively (i.e. mount -t iso9660 /dev/scd0 /mnt/cdrom2)?

No the cdrom is not blank.

this is what I get for Unrealtournament, --edit and other games --edit

mount -t iso9660 /dev/scd0 /mnt/cdrom2
mount: block device /dev/scd0 is write-protected, mounting read-only
mount: No medium found

for burned cds i get

mount -t iso9660 /dev/scd0 /mnt/cdrom2
mount: block device /dev/scd0 is write-protected, mounting read-only
mount: wrong fs type, bad option, bad superblock on /dev/scd0,
or too many mounted file systems

Its an odd one.

Hmm. Do you get the same errors if you use the device as a straight IDE device with no SCSI emu? Do other disks work ok or do they all fail?

Haven't had a chance to use as ide cause mandrake autodetected and setup the burner. It worked before i added the cdrom the other dcrom works.

I noticed this in dmsg

ttached scsi CD-ROM sr0 at scsi0, channel 0, id 3, lun 0
sr0: scsi3-mmc drive: 16x/40x writer cd/rw xa/form2 cdda tray
udf: registering filesystem
udf: bad mount option "codepage=850"
attempt to access beyond end of device
0b:00: rw=0, want=34, (=0x22), limit=2
isofs_read_super: bread failed, dev=0b:00, iso_blknum=16, block=16

does the code 850 have anything to do with it?

Dunno. You've got an IDE CDB. Here's the extract from my fstab for my cdb:
Code:
/dev/scd0       /mnt/cdrom2      iso9660 ro,iocharset=iso8859-15,nosuid,noauto,exec,user,nodev   0 0
(I don't have supermount enabled, so you'll have to type mount /mnt/cdrom2)

I know I will need to redo shortcuts is there anythign wlse I am missing, in this plan?

You don't necessarily need to edit your fstab if the only problem you're having is with supermount. man supermount should show that you need only type something along the lines of supermount -i disable (as root). HTH

When I supermount -i disable it gets rid of supermount in fstab. I can then mount cdrom. view cdrom contents. But when I mount cdrom2 i get this

mount cdrom2
mount: wrong fs type, bad option, bad superblock on /dev/scd0,
or too many mounted file systems
I can still cd cdrom2 but I cannot view cdrom contents.
I am going to take out the extra win_E and win_c they have nothing I need. when i mount -t cdrom2 it goes through no errors but still nothing when i ls. same when I mount -t /dev/scd0.
