Hi David,

  Yes and yes ! :)

  At the openfirmware prompt, issue a 'devalias' command and you'll see 
what some of the device-name shortcuts are. I'd say the second IDE drive 
would be 'hd1'.

  For a firewire drive, the alis is most likely

    fw/node/sbp-2/disk@0:X

  .. where X is the partition number.

  e.g. to boot from partition 3 on the external firewire drive:

0 > boot cd:,\boot\loader fw/node/sbp-2/disk@0:3

later,

Peter.
