Comment 1 Arjan van de Ven 2003-12-09 11:41:56 UTC
for 2.6 you need to drop the "ide-scsi" part (and maybe fix up the
/dev/cdrom symlink)

Comment 2 David Farning 2003-12-10 09:12:05 UTC
Removing the ide=scsi fixed the problem--thanks

Comment 3 Pascal Hurni 2004-01-25 23:53:33 UTC

Comment 4 P Fudd 2004-02-06 19:38:59 UTC
See /boot/grub/grub.conf, the first paragraph that starts with
'title', and the line in that paragraph that starts with 'kernel'. 
Near the end of the line, you should see 'ide=scsi'.  Delete that,
save, and reboot.
