Just a note, I looked into booting from CF in open firmware, looks like it can't be done on a Lombard.
One can get into open firmware, and then go
0 > dev /pci/cardbus@13
0 > words
and get a list of a lot of commands for the PCMCIA slot, but the needed command is "load",
it's not there, also not available for the USB ports, so can't boot from a USB key either.
If there's a way around this, using available commands, I'd be curious!
So the backup strategy is to copy all files to the CF card (which runs well), and if the disk goes bad,
install a new one, boot from CD, then copy files back onto the new disk.
Thanks!
