[Beowulf] SATA II - PXE+NFS - diskless compute nodes

[Eric Shook]

Michael,

This should be sufficient enough to run our software stack as they are 
tested on rhel 4 variants.  I will most definitely look closer at scyld 
CW4 to see if it fits our needs.

What does reimplementing pxe boot mean specifically?

Thanks,
Eric
