There is one model of the Macintosh (the Classic, I think) which really can
boot from ROM.  Holding down Command-Option-O-X (that's the letter O, not the
number zero) just after turning the computer on does the trick.  No boot disk
is required.

At least, I think that's the key combination.  I haven't tried it in a while.
It's possible that other models have this feature, but I doubt it.
