The reason is: kernel 2.4x emulate cdroms as scsi devices while 2.6x series
restores them back to what they are: IDE devices. That's why you got warning
of ide-scsi that sort of thing.
Try to do this:
1. find whether your cdroms are recongnized as /dev/hd* devices.
Here is my entry for cdroms in my fstab:
# <file system> <mount point> <type> <options> <dump> <pass>
/dev/hdd /media/cdrom0 iso9660 users,unhide,ro,noauto 0 0
/dev/hdc /media/cdrom1 iso9660 users,unhide,ro,noauto 0 0
2. try to load modules for ide devices. It is called ide-cd. try 'modprobe ide-cd'
You may want see this part in kernel configuration if you want compiling yourself
or see what happens:
Location:
-> Device Drivers
-> ATA/ATAPI/MFM/RLL support
-> ATA/ATAPI/MFM/RLL support (IDE [=y])
-> Enhanced IDE/MFM/RLL disk/cdrom/tape/floppy support (BLK_DEV_IDE [=y])
If you say Y here, the CD-ROM drive will be identified at boot time
along with other IDE devices, as "hdb" or "hdc"
3. look into your lilo.conf or menu.lst of grub and see if you have ide-scsi that
sort of thing appended to the kernel line? If you have, back the config files first
and then delete things like 'ide-scsi'
That's my two cents and hope it helps.
