RE: 4GB installed - RH reports 3.2?!?

Albert,

Thanks for your replies.  It seems that the hugemem kernel wasn't installed
by HP (even though it should have been).  I'm going to install WS4U1 over
the top of this installation anyway.  I'll be sure to install the hugemem
kernel with this one.

Thanks

Andrew

Andy,

  I would use the hugemem kernel that should hopefully fix your problem.
It sounds like with your current kernel PAE is not enabled.
