I have had my RX 401(CE) for over 2 years now. I want to upgrade from the Intel Celeron 2GHz processor, to a Pentium. I do not know which processors the SIS 651 motherboard will support and whether I will need to change the Bios settings or move jumpers.
You can't put in a Pentium, you would have to stick with Centrino (which I think goes to 2.8Ghz now) and make sure the FSB matches your board.
