What's the difference between the two models? Mine is 1U, 3 PCI slots at
66MHz/64 bits, 2 USB, 2 firewire 800, one firewire 400, serial, built-in
giga ethernet.

Of course you can do that, but if you revert OF settings to defaults,
you'll need to plug-in a keyboard and monitor to set it up again. With
the video board removed, serial is the default.

INSTALL.
It's not a problem of /etc/ttys: when running single-user that settigns
are not used to choose the console speed.

How does MacOS X works? They have a bootloader in the apple partition
map, right? Coulnd't we setup something like that? It would be possible
to dual boot easily.
