You probably have one of the older Mac Plusses
around with the early ROM revisions. I think it
was the "Lonely Hearts" revision that had this
problem. The only way to fix it is with a ROM
upgrade. Which will cost you.
ROMs of this revision would not allow the Plus
to boot with a hard disk that had not sufficiently
"warmed up" first. Hope that helps...
