I bought this board (DQ45EK) to be used in a VMWare VSphere installation, with VT-D support. (I am not talking about VT-X).
This option can indeed be enabled in the bios, but somehow it's messed up, because VMWare won't detect it.
I unfortunately flashed to the latest bios, and can't downgrade to other biosses to test if they do work. (Most of the time this is a bios issue).
I see for example bios 86 or 87, that mentions a fix for VT-D. I tried to flash that bios, but all older biosses get rejected by the flasher.
Is this not working VT-D a know issue? Are there any beta biosses available to fix this? Do I need to disable or enable other bios features to get this working?
Or is there a way I can downgrade my Bios?
I enabled almost everything in my bios, and now it does show up. Unfortunately it doesn't support passing through the onboard sata. So if someone is looking for that with vt-d, don't buy this board.
