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 9718 MPS=0x7ffd0000 map_pal_code: mapping PAL code [0x7ff40000-0x7ff7b000) into [0xe00000007fc00000- 0xe000000080000000) Warning: ignoring 0MB of memory above 1GB! Warning: ignoring 0MB of memory above 1GB! Warning: ignoring 2046MB of memory above 1GB! and I can only use 2GB of my 4GB machine? Greetings Christoph
