G3 problems booting internal ide: would pci-usb/firewire card boot?

[Marc]

This is a question for macos/linux on a Blue White (but on G3 266 as 
well,
where I solved the problem by putting 2 scsi inside, deleting the ide).

I have found a reference @ibm where they mentioned a method to boot 
linux
from external usb/firewire drive.

I'm curious whether I would be able to boot a usb/fiwi drive pci 
card-connected
instead of the internal usb/fiwi??
