Hi all
I've some strange problem with my single-core bi-proc (Opetron 248)
When I try to install FreeBSD 6.0 -i 386 I can't have all memory. When the
system boot (after recompiling kernel) I've see
~1 Go memory above 3 Go is ignored (not exactly something like that)
on boot.
If I put some
options MAXMEM=...
the kernel don't boot (more simple :-(( )
But if I install FreeBSD 6.0-amd 64 I've another strange problem (not very
important but...)

How can He detect 5Go when I've just 4 Go in the BIOS ?
It's HP Proliant DL 145 G2 with 4 Go of ram.
I think is something in the bios but well I've try many combinaison nothing
work (well no exactly true, because with some combinaison the kernel see
only... 2Go...)
Anyone have see this problem before ?
Regards.
