Despite not being intended for servers and EOL, the DQ35JO seems fine with W2k8 R2
2 drivers were not found, of course, they were the AMT/MEI ones and the windows 7 ones installed fine.
While it is not a server board, the DQ series are cheaper, easier to find (well, they were until T-Zone went belly up)
and work just fine for what I want to use. The remote control works too, since all I need is the occasional "reboot the stiff."
I gave up on the intel raid because enabling UEFI stops the keyboard working when you need to type CTRL-I,
but I did have one go through where I disabled, UEFI, set up the raid, renabled UEFI, booted and installed w2k8 r2.
The old board is now having a thrash installing sqlexpress.
