So why do I get the following:

Linux version 2.4.0-0.8smp (root@boris.devel.redhat.com) (gcc version 2.9-ia64-0
00216-final) #1 SMP Sun Jun 18 00:32:35 EDT 2000
EFI v0.92 by INTEL AL460GX.86B.0027.D27.021800: SALsystab=0x7ff29d60 ACPI=0x7ffd

Warning: ignoring 0MB of memory above 1GB!

and I can only use 2GB of my 4GB machine?
