I am a user of FreeBSD-4.7.
I baught a Mother board(P4QH6) with Xeon MP from Supermicro.
Supermicro says about P4QH6
Yes the MP Xeons and this motherboard can fully access 32GB of main
memory. The processor is a 32 bit instruction code processor, but is a
64 bit device which easily accesses 32GB of main memory.
This doesn't parse quite right, but it definitely seems incorrect in
any case. The Xeon is a 32-bit device, period. It has 4GB of
address space, period. What this system can do is window into the
memory in some fairly sophisticated ways, but it's still only a 4GB
address space.
How should I do to let FreeBSD-4.7/5.0 access to 32GB mem?
So far as I know, nobody is working on supporting this
functionality, because it's a fairly slow way of getting access to
extra memory.
IA64 is available for it?
No. IA64 is strictly for Itanium, at least for the moment. Xeons
are *not* IA64.
Or Shoul I chose any other operationg system?
Windows is the only system that will use it at all well, but I seem
to recall that Linux had some work on support for it. For nearly
any general-computing application, though, you'll get better
performance at a given price by using systems that can address all
of their own memory directly.
