Asus K8V and Athlon 64 3200+ dumb question

[kevman]

Anyone know how to set th CPU to 64 bit mode? I looked at the manual, bios, etc I have not been able to intuitively find it. I would have thought it to be either a jumper or BIOS setting but there was no reference to that in the manual.
Any help would be appreciated.

Thanks

You do it by installing a 64-bit OS, not by tweaking at the BIOS level.
