I'm migrating my main system and have setup a temporary alternate system on a spare machine. I just thought you might like to know the support on this motherboard.

Gigabyte EP45T-UD3R (a socket 775 Intel ICH10-R machine, I had a Core 2 Quad installed and 4 GB ram).

Standard installation worked fine (CD Rom installer onto a USB stick)
Onboard Realtek 8168 Gigabit Ethernet works.
Onboard ICH10 6-port SATA works (esxi doesn't mention the -R)

Health Status shows only 'Processors' and 'Software Components'
Naturally there's no DirectPath IO
Power Management says Technology: Enhanced Intel Speedstep, Active Policy: Not Supported, and it is not possible to click on 'properties'.

With no VMs running, 890 MB of RAM is used.
