I'm running something like that on another machine, but can't on this one. The gory details include the fact that this is a mac pro. It's EFI firmware only does magic bios emulation if it sees an MBR formatted disk and so setting things up via GPT won't work for me. I did try it using the link that you pointed to above and it wouldn't boot. Tried it via the apple's firmware "choose a boot disk by holding down the option key" trick and via rEFIt. g. _______________________________________________ [email protected] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "[email protected]"
