It works when booting from the = graphical boot chooser (obtained by holding down the Option key during = boot), but I couldn't figure out a way to boot from an external FireWire = drive from the OpenFirmware prompt (Cmd-Opt-O-F startup). All of the = examples I could find refer to booting from the internal hard drive or = from the CD-ROM drive. My motivation is that I want to test FreeBSD on a headless Xserve G5 = that lacks the capability for a graphical boot chooser, but does allow = booting via OpenFirmware over a serial terminal. The workaround arrived = at in my previous message allows booting from the external FireWire = drive, but still requires an Install CD or /boot/loader to be present on = the internal hard drive. Cheers, Paul.
