you mean to 2.4.X ? '7.2 is the version of the redhat distribution. not
the version of a kernel. the kernel is now at version 2.4.something.

the kernel needs to be compiled differently for a single-processor machine
(uni-processor) and for a multi-processor machine (SMP), since some of the
code changes between the 2 options. a uni-processor CPU won't work for a
multi-processor machine (or perhaps will work with only one of the CPUs? i
have no experience with that), and an SMP kernel will lock-up during boot
on a single-CPU machine (happened to me lately).
