Linux and 2 CD-roms

[Kevin Craft]

 In the original message it was stated he had two CD's he wished to use together (I
made the assumption he wanted to use the RW as a writer and not just as another IDE
CDROM). With one of them being a RW, and if they are both ATAPI IDE drives, a
compile will be needed.

The kernel will have to be compiled with these options:

 1) Disable generic IDE/ATAPI CDROM support
 2) Enable SCSI emulation support
 3) Enable SCSI support
 4) Enable SCSI CDROM support
 5) Enable SCSI generic support


 Some of the above may already be enabled, the important one is disabling the
IDE/ATAPI CDROM support. I can't speak for other distributions, but in both Redhat
and Mandrake the above is needed. Afterwards, both drives are accessed as if they
are SCSI devices....ie;

(from my /etc/fstab)

/mnt/cdrom /mnt/cdrom supermount fs=iso9660,dev=/dev/sr0 0 0
/mnt/cdrom2 /mnt/cdrom2 supermount fs=iso9660,dev=/dev/sr1 0 0

 As a rough definition, ATAPI is nothing more than a method for translating the
SCSI commands the drive uses through a IDE port.
