Intel Xeon EM64T Processor and correct port

[John R. Shannon]

Is AMD64 the correct port for E7520 chipset with:

mainbus0: Intel MP Specification (Version 1.4) (INTEL Lindenhurst )
cpu0 at mainbus0: apid 0 (boot processor)
cpu0: Intel(R) Xeon(TM) CPU 3.20GHz, 3200.31 MHz
cpu0: features: bffbfbff<FPU,VME,DE,PSE,TSC,MSR,PAE,MCE,CX8,APIC,SEP,MTRR>
cpu0: features: bffbfbff<PGE,MCA,CMOV,PAT,PSE36,MPC,NOX,B21,MMXX,MMX>
cpu0: features: bffbfbff<FXSR,SSE,SSE2,B27,B28,LONG,3DNOW>
cpu0: L2 cache 1 MB 64B/line 8-way
cpu0: calibrating local timer
cpu0: apic clock running at 200 MHz

This may not be too helpful, but this is kind of a chicken and egg
thing. Where did you get this dmesg from? An i386 kernel? I'm not good
enough to tell you if that's a 64 bit CPU unfortunately.

I quick google search shows that the Lindenhurst chipset, e.g. E7520, is for EM64T processors so the amd64 should work on your system. That said, unless you have a compelling reason to do so, the i386 port works fine too, and at _present_, some things are still easier to do with the i386 port, e.g. java and linux emulation.

I have a similar system running xen with netbsd-3/i386 on dom0 and the domU's and so far no complaints. Someday, xen 3 will work with the amd64 port, in which case I'll make the switch.

I agree to an extent.

I have an amd64 box, and while I'm the coolest guy on my block by far
for running an actual 64 bit OS on 64 bit hardware (heh), the
flexibility of i386 would be useful. Some stuff I'd like to use
doesn't build, etc.

Me too. My desktop box is running a dual core cpu w/ amd64-current. It's just missing too many things to switch my servers over just yet, although it's getting better pretty quickly.

I've been exclusively buying 64bit hardware for the last 4 months, even though I continue to run the i386 port on all my production systems.
