P55m-UD2 and AHCI problems
Hi all,
I've had some issues in the past with my current motherboard (gigabyte p55m-ud2) and have recently updated the bios to f7 and was hoping for some help.
Previously, I've had issues with the motherboard not detecting IDE optical drives correctly with AHCI enabled, so I was forced to install W7 using RAID/IDE mode so the DVD drive would actually detect and install.
Ever since I have had W7 installed, the optical drive has still never worked correctly (detects as SCSI), and only allows me to read but never write (it constantly fails). I've searched around and found it to be a common issue with my model LG dvdrw, with most people suggesting to upgrade to a sata dvdrw.
I have now updated my BIOS to the latest, with some reports of certain IDE optical drives actually functioning correctly- but have run into additional problems.
The first issue, is that windows is telling me that my version of windows is no longer genuine (which I have put down to it detecting a hardware change, as the bios revision has changed).
Secondly, I have tried to enable AHCI mode and during boot either freezes after post, displaying an "Loading operating system" screen, or freezes after the intro animation and gives a BSOD (with varying error messages each time).
I've considered purchasing a new dvd drive and starting from scratch, as I remember reading somewhere that you are required to select AHCI mode on the intial install and it can't be changed afterwards.
Can anyone shed some light on this issue for me? If i'm going to have to do a reinstall, there is no point in me activating windows again.
Thanks,
Luke
