Especially with a Beige, and possibly also with a pre-Beige, running X, 
is is often necessary to get at least 5 chimes (four wouldn't do) during 
a PRAM reset in order to really clean it out.

On the Beige, one or more EIDE channels can be lost, and others can be 
screwed up.

Discovered on pre-Beta X, and perhaps carried on to early Golden versions 
as well.

My "drill" when real weirdness happens is to get 10 chimes during a PRAM 
reset, and then let the machine run free.

Based upon the "law of averages", it takes 7.5 chimes to make absolutely 
sure the PRAM is clean ;-)
