FreeBSD 7.1 on HP ProLiant DL580 G5

[Antonio Tommasi]

Hi to all,
i have recently buied 3 hp proliant dl580 G5 (intel xeon 64-bit) with 
administration console and i'm trying to install FreeBSD 7.1 amd64.
Installation has successfuly only in one of these; in the others my 
installation block with an internal error on the system insight display 
(blink red led).
If i try to install suse enterprise server 10 sp1 i haven't any problem.
if i try to install suse enterprise server 10 sp1 and to interrupt 
installation and then to installa freebsd sometimes i can install 
freebsd, but if i reboot machine there is probabilities that server 
block on restart.
Is a bios problem or configuration?
Any ideas?

Thanks in advance
