The x79, x99 and Haswell DMG have all been updated. Included with this update is the inclusion of the new HDMI Audio Edit required for the new Nvidia 900 Series Graphic Cards. This is the only change with the x79 DMG at this time.
As for the x99 and Haswell DMG minor updates have been applied. We still need a large amount of IOREG’s from most boards. If you do not supply the IOREG’s we can not optimize the SSDT’s.
A larger update for x99 is ready however we selected to wait until we are done BETA testing the new EVGA Motherboards. Once this is done later this week we will be releasing the update.
