Application code compiled for a P4 (using full P4 optimizations) usually won't run on a P3, I suspect the same for kernels. I betcha you need to

dude.... the i686 kernel works fine on P-2 / P-3 / P-4. there is _no_ code in CentOS3/i386 and CentOS4/i386 that wont run on a machine that is an i686 Arch type.

Unless you are talking about P-4's with EM64T / x8664. But I presume, knowing the system is a P-3, Tom didnt install x86_64 on there.

( I dont think you would even see the grub prompt in that case, but I havent tried running a x86_64 OS on a P-3 )

Happy to stand corrected, I wasn't sure about that. SuSE installs a different kernel (from the same distro) on P3's & P4's ....
