Considering the nature of this issue, we would appreciate if you could contact our support department:
I have exact the same problem with DP67BG (no possible boot drives, when UEFI boot is enabled and SATA operates in AHCI mode + computer freezes for five minutes on first screen (Intel logo and options for BIOS setup)), except that my BIOS version is the latest for now (2111). SATA0 is Corsair SSD SATA III, SATA1 is Optiarc DVD RW SATA II, SATA2-5 is WD 500GB SATA II HDD.
If you have found a solution - it would be nice to hear it. Thanks.
Hi, I have the same problem too with firmware version 2161 and the older version before wih windows 7 and 8 Consumer preview (x64) if you have a solution !
Still haven't found a solution. Windows 8 is currently installing (despite claiming it wouldn't be able to boot, unlike when the controller is set to RAID mode), I guess I will see what happens.
Have to amend myself here. Using the April BIOS release, this works (although Windows setup claims it will not).
