subject: Upgrading PII/III Boards

Hi, Matt.

Some weeks back, you posted about some glitches while trying to change
CPU cartridges in a PII or PII/III board.  I can't find that post, so
I'll ask if you will please refresh my memory.

BIR, when you tried to install a cpu of different speed, it wasn't
recognized, and you had to put the previous cpu back in there, and reset
the speed for the replacement in SETUP, then power down, put in the
replacement, and then it would work upon repowering?

Do you recall what those cpu speeds were, and what the mainboard chipset
was?  I presume that the mainboard CLOCKMUL settings were jumperless,
and autodected by the system?

Reason I ask, there are only a couple of us where I volunteer who do
most of the work with PII/III boards, and we have some which seem dead
when we try them.  We have various speed cpu cartridges for test, but
we may not remember to try more than one speed cpu on the
boards which are jumperless wrt clock multiplier.  The older fellows on
the day-shift just leave these boards for us to find up on some shelves,
with almost never any note about any symptoms, or whether they were
presumed good when removed from their previous home. Some show up in
boxes, so those might be either upgrade pulls or dead ones which have
been replaced.

We've seen a number of boards with those "bulging tops" on the large
caps near the cpu, and when those boards don't work right off, we give
up on them especially quickly.

Thanks - - -  JimH.
