resoldering a pin on a pentium cpu??

I've got a socket 370 PIII chipset that had one of the pin separate.
Anyone here had experience in re-attaching these.
The break is clean( the copper trace on the chipset itself is visible
and exposed.) and the pin has a bit of the board resin on the tip so
it should be possible to re-attach it.
Just concerned about applying a solder tip to the chip itself.(I do
have a range of irons, from 20 watts up to 150.)
Or is there a cement that could be used?
Oddly enough the chip seemed to work when it was swapped out to
another tower though I didn't run any heavy load on the system to
checck it out.(Booted up just fine with bios correctly identifying the
chip with no beeps or hangs.)
If it's not advisible to try soldering I suppose it might work to
manually drop the pin in the correct hole in the socket and put the
chipset with enough pressure to make contact and lock it in place with
ziff latching lever.
Any advice is greatly appreciated.
 
Looks like you were lucky-- most chipsets have many duplicate power
pins-- your broken pin is likely one of those. It should work fine as
there's likely at least five other similar pins.

Thanks for the info.
Is there a pinout for pga370 chips on the web anywhere?
This particular chipset is a Pentium PIII but doesn't have any
identifying info on it to tell what model or gen it is. ( It is a
800mhz, that from the bios info on boot up, but no serial # there
either.)
Thanks again.

Everything you ever wanted to know about the P3 (and a hell of a lot more):

Pinout begins on pg. 68

As others have said, if it's working, you should leave it alone.
Chances are good that it's a power or ground pin. It could also be a
pin that's not needed on that CPU (eg. a multiplier pin that's set to
open circuit for that speed CPU). It is possible to solder these pins
back on, but it's not something for a beginner. If you get any nearby
pins hot, they will fall off and a solder splash would be almost
impossible to clean up.
