My FEH (12/5/97) indicates that 167MHz CPUs may be possible too. J2701
(situated above the CHEERIO chip) should be set to 1-2 for 250/300MHz
and 2-3 for 167/200MHz, this is for E450 motherboard part no 501-2996.
It also indicates the installation sequence of CPU modules and DIMMs is
different for particular revisions, and says absolutely nothing about
modules faster than 300MHz. I also seem to remember something about an
Ultra non-Enterprise 450, but that was a while ago now. Perhaps this
might spark (no pun intended) something in James' memory?
