CentOS - Sep 2005 - centos 4 installed on P4 won't boot on P3

Hi,

I installed centos 4 on a P4, configured it (and it booted fine here) 
then sent it to the DC to be put in a P3 but it won't boot, displays 
GRUB and halts.

The DC guys tried grub-install in rescue mode but still the same.

Any clues? Is there some difference between P3 and P4?

thanks
tom

Happends when the MotherBoard chipset differs to much (usually ide
controllers)
We had similar problems with P4 with via & intel chipset.
You may nedd to do a new install on that p3.

did they check the drive lables ?

is /boot/grub/grub.conf configured to point at reality ? or is it 
looking at non-existant stuff ...

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 
do the install again on the P3. I also betcha if you did the P3 1st & 
then moved that disk to the P4 it would work. Newer CPUs can usually run 
older code, but not vice-versa. YMMV & all that :-).
