Looking to upgrade the CPU in this ere old Sony VGN-A197VP. Its got a Pentium M 1.6GHz, 400MHz FSB, socket M (aka 479 mPGA) SL6FA As far as I can find out I can upgrade it to Pentium M 2.1GHz SL7V3 or *maybe* Core 2 Duo T5300 1.73GHz 533FSB SL9WE (unsure if the BIOS will support the EM64T needed for this one to work) Anyone got either of these CPUs they wouldn't mind parting with for a few beer tokens?
