Yesterday, I bought a AMD AM2-64 X4000 CPU and of course also a new motherboard and 1GB of DDR2 RAM to support the new CPU. My first thought was that I need to reinstall my Linux OS to 64bit. But then, I learn from the shopkeeper that 64-bit is backwards compatible to 32-bit.

This new motherboard only comes with one PATA IDE, and the rest are SATA. However, when I plugged in my PCI IDE card with 3 PATA hard disks connected, I got the GRUB Error 22 message.

I guess there is something to do with the PCI IDE card. Hope to solve it by this week.
