64-bit compatible?

[Moozillaaa]

What determines whether or not a CPU/mobo combo will handle Linux 64-bit OS's?

I'm building another desktop, and I'm liking speedy Karmic 64-bit on my HP laptop...

You would need to check if the mobo supports a 64-bit CPU and then you would need to buy the 64-bit CPU

I think you have to look hard to find a CPU that's not 64 bit compatible. The only current CPU i can think of is some of the Atom processors used in netbooks.

If the CPU supports 64bit, then the chipset will as well. Its all about the CPU.
