SUMMARY: How to boot from external CD-Rom-drive?

Hello managers,

i've asked how to boot off from my external cdrom-drive, because
my internal is defective.

Thank you very much for all your answers!

To sum it up:

->  ok> probe-scsi-all
    will show me the exact path of my external cdrom-drive
    (something like /pci@1f,4000/scsi@3,1/disk@4,0:f or similar)

then
->  ok boot /pci@1f,4000/scsi@3,1/disk@4,0:f

    should do the trick...

Additionally i could define another alias with "devalias"
to have a "cdrom2" for the future, but i don't think
i'll need that.

With regards,

Bernt Christandl
