pardon my naivety, but wasn't the whole point of moving to the the 64 bit
architecture was to push and solve the problems of--
	o larger numbers.
	o allowing more memory.
	o larger number transactions (finance and tax applications)
	o large disk sizes, etc..
	o higher precision in scientfic simulators, and other simuation machines.
As well as to get ride of the control Microsoft has over the IBM's and
dells. Just had to add that bit in there, read the court findings you know.


take care,

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

map_pal_code: mapping PAL code [0x7ff40000-0x7ff7b000) into

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
