: Sorry, it's software raid.

: When you say "Software RAID: connect it and boot off it." is that with scsi
: or ide.

I think he means:

* Shut down the system and power off

* hook up the CDR drive (as a slave on an IDE bus). Power up and boot
off it. Yes, IDE HD performance will go down a notch (eg my HD are
udma5 but best is udma2 with CRD on the IDE bus). But "so what" - it's
only temporary" :-)

* When you are done, power down, remove CDR and reboot.

This is certainly possible - a $0 cost solution if you don't mind a bit
of bother.
