Hi all,
i'm going to renew my htpc, transitioning from a Athlon-XP 3000, to a
Pentium-M solution.
In detail:
Motherboard:AOpen i915GMm-HFS
CPU: any Pentium-M rainging from 750 to 780.
Here comes my troubles:
The mobo says it support 479-pin CPU, but i find a lot of ebay auctions
where CPU stated as 479 chip, are instead described by the intel
Processor Spec finder, as 478 pin.
Further details: the mobo manual says: "This socket supports uFCPGA &
uFCBGA package CPU", and this gives me even more confusion.
Can someone give me a clear explanation of which kind of CPU i need to
buy?
thanks in advance
"478 pin Micro-FCPGA and 479 ball Micro-FCBGA packages". The socket
on your motherboard has 479 holes. One hole is blocked out of the
480 maximum positions, leaving 479 holes. The pin grid array chip
(FCPGA) that plugs into the socket, seems to have 478 pins, and
two pins are missing in one corner. (The BGA version looks like it
is intended to solder right to a PCB, and has 479 balls that
match the S479 socket pattern.)

The Q-Spec processors in the list are Engineering Samples, as
I guess retail FSB533 processors weren't available for testing.

I think as long as the product you buy lists 478 pins, everything
should be OK. The Socket is "S479", but the pin grid array
processors that will fit the socket seem to have 478 pins.
Using either the SSpec or the Order Code, and
processorfinder.intel.com , you should be able to get
some info on what you are buying. I hope you cannot
actually find any FCBGA 479 ball packaged processors
at retail (like on Newegg), because an end user cannot
solder those (easily) to a blank PCB.
The list of Pentium M processors is here. Click "Go" and
wait and wait. If you are on dialup, you'll be old and
grey before this finishes rendering. (I used a copy
of Lynx to make the text listed below.)
