P2B Tualatin upgrade questions...

[ray field]

Having successfully upgraded a P2B-S last fall to a 1.2
Celeron with the Upgradeware slotket, I recently bought a
used P2-B to replace an old motherboard (a Supermicro that
was never much good) for my secondary machine. The board is
a Rev. 1.10, which I thought was sufficient (it took the
1014 bios upgrade just fine) but the specs on the
Upgradeware site say

Please note that the PWM IC must be "HIP6019BCB , HIP6004BCB
or US3007CW ". If it is "HIP6019CB or HIP6004ACB", your
system can't be upgraded.

I've looked all over the board, and can't find the PWM IC,
though I'm a little hampered by the fact I don't really know
what one is.

Finally, if I'm able to do this upgrade I wonder what
jumpers I'll have to change -- I got this board working with
an old PII-233 I had lying around, but had to move some
jumpers to get that to boot, and I don't really know what
I'd be up to if I buy like a 1.4 Ghz Celeron.

That's a little rectangular chip with 20 feet somewhere near the CPU
slot.

You'd only have to set up the board for 100 MHz FSB operation, nothing
more.

Thank you! Very hard to see the number but I'm thankful
to report it qualifies.

Not sure what this means, and doing a quick search on the
PDF version of the manual only turned up a small reference
to FSB.

The bus frequency now is set to 66MHz -- will I need to
change that to 100Mhz? And the multipliers make no
difference?

Thanks again.

Yes.

Correct. Newer Intel CPU are all multiplier locked (save some
engineering samples) and thus don't care about this setting.

thanks once again. it arrived today, went in without a
hitch, just needed to tell the BIOS to ignore that voltage
thingie...
