FreeBSD on Shuttle SB81P

I bought a new Shuttle SB81P to use as a VMWare GSX server in my Network Security Operations class. I bought the system to provide VMWare images which students could independently manipulate. This will make the class more hands-on without requiring much investment on the student's part. All I will ask is that the student brings a laptop with a Secure Shell client. If the student wants to directly interact with the VM, he or she can install the VMWare Virtual Console for Windows or Linux on a laptop. I cannot use FreeBSD to host GSX Server. I intend to try the Windows Server 2003, Enterprise x64 Edition (64-bit) trial version. If it works as promised I will buy the Standard Edition from a vendor like

Here are the Shuttle specifications:

  • Shuttle SB81P Intel Socket T(LGA775) Intel Pentium 4/Celeron INTEL 915G Barebone from

  • Intel Pentium 4 640 Prescott 800MHz FSB 2MB L2 Cache LGA 775 EM64T Processor from

  • 2x1GB 184-pin DIMM DDR PC3200 RAM

  • Two Western Digital Raptor WD740GD 74GB 10,000 RPM 8MB Cache Serial ATA150 Hard Drives from

  • NEC Black IDE DVD Burner Model ND-3540A from

  • NEC Black 1.44MB 3.5" Internal Floppy Drive from

  • Shuttle PF60 XPC Carrying Case from

Since the NYCBUG dmesg submission system isn't working, here is my dmesg output from the FreeBSD/amd64 port of FreeBSD 6.0-BETA2.
Here is how long it took to build a kernel:

The CPU supports hyper-threading. Notice the C column in top output.

Here are OpenSSL speed and nbench test results. I ran these tests after reading this thread.

I can't remember if the change was made before or after 6.0-BETA2, but note that Hyper-Threading is now disabled by default on RELENG_6 for security reasons.
