Hello list,

Is there any limit on the amount of memory that can be used
with FreeBSD 6.x/amd64 ?  I found that FreeBSD/ia64
currently has 2GB limit.  I was wondering how amd64 is like.

Specifically, I am thinking of a Dual-core x Dual-processor
Xeon 5160, with 5000P chipset and something like 40GB of

I'd appreciate if someone would tell me if the system can
use the whole memory, and/or if one single process can use
the whole memory (or at least most of it)?

Are there any other things to be noted? like.. some
popular hardware not working with > 4GB memory and such.
I don't need much fancy hardware, but would like to expect
SATA disks, ATAPI CDs and Gb Ethernet NICs to work..

Any other experiences are appreciated as well.

I've just joined the list now.  I briefly searched the
archives, but in vain.  So any keywords for archive search
is also appreciated.

Thank you.
Hiroharu Tamaru
