Okay, what "and stuff"? And as modules or into the kernel? Let us know 
what you did with ide-cd, scsi, ide-scsi, sg, and sr. Before I go much 
further, you might want to take a look at:

Good so far. Exactly what happens depends on whether ide-scsi is a 
module or compiled into the kernel. Either one is okay, but we need to 
know which you have done. And most of the rest depends on that, also.

cdrecord uses the "sg" driver, and the /dev/sg* device files. Did you 
compile in "sg"?

If you have compiled some of the pieces mentioned above as modules, then 
show us your /etc/modules.conf. If everything is in the kernel, then 
execute "dmesg", and post anything that looks like it might be related 
to disks or scsi.

The file /dev/cdrom is typically just a symbolic link. If you are not 
using ide-scsi, then it would point to /dev/hdc (or whatever). When you 
are using ide-scsi, you would change /dev/cdrom to point to (usually) 
/dev/scd0. Your second CD-ROM would normally be /dev/scd1, and you could 
make /dev/cdrom1 point to that.

The output of dmesg will tell you for certain what device to use, for 
example:
   sr0: scsi3-mmc drive: 32x/32x writer cd/rw
The "sr0" is the same as /dev/scd0 (if you look at /dev/sr0 and 
/dev/scd0, they should be the same).

No. Those lines in lilo.conf tell lilo not to attach the ide driver to 
the CD-ROMs. A necessity if you want to attach the ide-scsi driver to them.
