cd /dev
ln -sf sr0 dvd
ln -sf sr1 cdrw
Of course you have to change the lines in /etc/fstab accordingly.

Just look at the kernel messages after booting the system:
dmesg | grep emulation
On my machine, the following output is produced:
ide-cd: passing drive hdc to ide-scsi emulation.
^^^
scsi0 : SCSI host adapter emulation for IDE ATAPI devices
On my machine /dev/hdc is the CD drive. If I wanted to turn off SCSI
emulation, I'd remove the hdc=scsi from /etc/lilo.conf and reinstall
lilo.
bye,
Chris
