To my knowledge, there is no official way to run Coppermine CPUs smoothly
on HP Netserver E60, since latest BIOS provides no microcode support, thus
renders server incapable of (re)booting without human intervention, that
is, it is required someone to press F1 in order to continue booting.
For personal needs, I have bypassed that problem, so currently, I am able
to run Coppermine processors on Netserver E60 without any glitches.
