OF booting of G3-upgraded 7600?

One simple thing that bit me is that the machine can try to boot before
the hard drive hs spun up.  This gives the default catch you're seeing,
and it depends on CPU speed.

I fixed it with an OpenFirmware change that I haven't bothered to fully
understand, but which seems to work great.  That is:
begin ['] boot catch 1000 ms cr again

(I got this from some unremembered place on the Web that discusses Open
Firmware boot problems...)
