Hi,
I was wondering what march to specify in my cflags for the Intel Core
Duo L2400 processor. The gentoo-wiki says that the safe cflag is
prescott, but I figured I would ask here to find the optimal for this
processor, or if the prescott is truly the safest/optimal.
Here is my /proc/cpuinfo for it:
