On previous boards, you were able to config the 3rd party controller (AHCI/IDE/RAID etc) but on the Z77 Pro there are no options other than on/off and Option ROM on/off.
I've asked an Asus official about it on [H]ardForum.
grambo, or anyone else, have you ever heard back about this issue?
I have the ASUS Maximus V Gene, and the Asmedia controlled 6G ports cannot be configured in the BIOS. They are IDE by default and you can't set them to ACHI or other mode. Like you say, it only gives the options to enable/disable and ROM on/off.
Now here is the problem with that: Those Asmedia 6G ports are clearly for hooking up additional Sata3 SSD's. Well, I have two SSD's, one is the OS drive that I put on the Intel controlled 6G port, and the other I put on the Asmedia controlled port. But because the Asmedia ports cannot be configured, the system reads the Asmedia connected SSD as Disk 0, and the Intel controlled one as Disk 1.
When I install Windows to the Intel drive (via USB), when the install process has to reboot, it cannot find the Intel controlled drive because the other drive connected to Asmedia controller is seen as the first drive. Even when I disable the Asmedia controlled SSD from the boot order and HDD order, I cannot get the system to boot into the Intel-controlled SSD I'm installing the OS to, UNLESS I unplug the Asmedia controlled SSD.
So basically, IDE is taking precedence over ACHI (my Intel controlled SSD is in ACHI mode), so the Asmedia controlled SSD prevents the reboot into the Intel-controlled SSD. So this means you can't install Windows to your Intel controlled SSD when you have a SSD hooked up to the Asmedia controller as well.
This is unacceptable to me, as I bought this board to be a stable power board that would help in what I intended to do with it: namely, sysprep and create Windows images, run VM's, do many actual OS installs to test drivers over hardware platforms, etc. So I will be installing Windows hundreds if not thousands of times on this board. So now I will be unplugging the Asmedia connected drives every time I install Windows? I don't think so ASUS
I can tell you this: I would NEVER, NEVER, NEVER have bought this Maximus V Gene motherboard if I knew it was going to do that. I have a P8Z68 Deluxe board, and an MSI-Z68MA-ED55(b3) and I have never experienced such an amateur problem with any board in my life. I'm really disappointed in ASUS right now. "JJ" talking bull**** on NewEgg as if they went all out with these boards. Well, it's not going all out if you limit configuration options for the non-Intel controllers, effectively putting the drives connected to those in primary position, causing the Intel controlled drives to be overlooked during OS install. This is unacceptable.
Please tell me there is solution to this, or that ASUS is going to upgrade their retarded BIOS for these boards...Edited by Troubad - 6/24/12 at 4:45pm
