kernel panic

hi Pablo,

There is an earlier version of NBP ( aka linux.0 ) which can't handle memory > 
768 MB.  Grab an NBP off the net.  Linux.c has a code segment that figures 
out the amount of memory on the machine.  You should see a code segment that 
computes memory for machines that have < 768 MB and a code segment that 
computes memory for machines with > 768 MB.  I know that pxe-0.1-33.src.rpm 
for redhat has the NBP that can handle the extra memory.  pxe-0.1-28.src.rpm 
did not.
