Boot from External USB DVD Drive?

[Talbs13]

Hello,

Is it possible to boot from a External USB DVD Drive?

Holding Option key doesnt show it and holding 'c' doesnt boot. Maybe i have answered my own question.

Cheers

I don't know whether you can boot from it, but I do know that the USB drive has shown up when holding the option key (so presumably can be used to boot...)

Tried another disk?
