Most Linux distributions will "support" the Pentium 4 and Xeon. The
question is if the kernel is compiled to take advantage of the newer
The Scyld distribution now has about a dozen different kernels to match the
processor types and UP/SMP on the master and compute nodes. Typically
only two to four of the kernels are installed, based which checkboxes
are slected during installation. We always install a safe, featureless
BTW, you might think that the processor family is the most important
optimization, but there is an even bigger difference between
uniprocessor and SMP kernels.

You pretty much have two choices:
be library version compatible with a consumer/workstation
distribution (Red Hat, SuSE, Debian), or
use a meta-distribution such as GenToo or Debian and compile

Every few weeks Intel comes out with a new card version with a new PCI
ID. The e1000 driver is one of the five or so drivers that we are
constantly updating to support just-introduced chips.
