Is there something I can tell people to do at the OF prompt that will load and run the stage-one boot loader?I was not able to figure out how to do it from OF. Apple machines are looking for the blessed file if 'C' key is held pressed during the machine start-up. It is the "official" manufacturer prescribed way to boot a Mac from a CD/DVD.
I tried
boot usb0/disk@1:2.\\:tbxi
This appears to load the stage-one boot loader, but unfortunately, the
stage-one is apparently looking for a physical CD and gives up when it
doesn't find one. I suppose I could change the "cd" devalias to point
to the USB stick, but that might have unknown ramifications later on
that would be messy when you want to boot from the physical CD-ROM.
I guess I'll just warn folks that they need to use "install32" if they don't have a G5 machine.
Enjoy! RickPS: As you say, what I'm trying to do is only partially supported by Apple, and doing unsupported stuff may have unpredictable results. It's probably best to leave well-enough alone.
