Yes, it shouldn't matter if you have AHCI enabled for all or just one, but as Ace mentioned you should disable stuff you are not using.
AHCI should work if RAID works, and visa versa as they use the same ROM. I'd say his BIOS edit and mine are probably exactly the same.
Jay113, if you use AHCI with no disks connected will it boot all the way to boot disk error/NO OS message? If so, try it again with your hard drive connected (First SATAII_0) port, but with no CD/DVD drive connected as mentioned, then if it boots you will know the CD/DVD drive is the issue. If it still fails then connect an older drive if you have one and remove the CD/DVD drive, if it then boots add back the CD/DVD drive and see if it still works.
If it does, then there is something wrong with your main hard drive. I have seen this before, a working drive that was still in some way faulty causing AHCI/RAID to not work, but worked fine in IDE mode and was eventually replaced with another drive that exhibited no issues.
I tried you bios (LSD) and same thing again. I don't use RAID mode.
I disabled AHCI for other chipsets => same issue. I disconnected all SATA devices (I have 1 SATA DVD drive + 1 SSD + 2 HDD) => same issue. (By way the way I didn't try to remove my IDE DVD drive)
Just after the BIOS splash screen, I don't see the AHCI bios. I have a 3 secs blank screen, and reboot, Again and again. I have to swich off my PSU if I want to boot successfully.
I saw the POST error code on my mobo. The reboot appends when the debug LED shows 89.
I found the problem. My usb keyboard : Logitech Illuminated. And I think there is no solution for the moment. When I use a "normal" keyboard, I don't have this problem

I got also same keyboard and have problem before in P55 system BIOS.

I have your same keyboard and I had similar boot problems. It took me forever to figure it out because I was looking for other reasons. This particular Logitech model has issues, the problem is that it uses too much power so Gigabyte has to release a bios that allows for high powered devices like that to be recognized before POST.
Anyway, glad you fixed your problems. I hope this can be fixed in the next bios because I really like the keyboard and I don't want to change it. My solution is booting without keyboard (after setting NO ERRORS in the bios so the missing keyboard doesn't stop the boot) and then plugging it later when in windows.
Not an elegant solution (it's very annoying) but at least I can use the same keyboard until this is fixed. A better solution is plugging the keyboard in a PCI USB extension card ($15) instead of using the motherboards native USB ports.
Im using Logitech G15 which is an illuminated keyboard and from time to time my board would report "overclocks failed" from cold boot. Giga P67A-UD5/2600K
