Asus C90P AHCI request (same situation as P5K)
#1
Hello everyone,

I am new here, so I hope I post this in the correct section, but here goes:

The Asus C90P had AHCI enabled in the original bios. Somehow they disabled it in later bios releases.

I am currently using a modified BIOS version 0803 (which enables quadcore support).

I can see the options for AHCI are still in the bios when I open it with AMIBCP.

Asus has done this for multiple desktop boards, and I saw that a lot of those boards (like the P5K) got fixed by this community.
Can anyone help me with this bios?

I was looking around if I could fix this myself, but apperantly it isn't as easy as adding a little micro-code for other cpu's.

I fixed it myself! Big Grin
Here is the 0901 bios I created.

Changes compared to 0803:
-updated microcode core2 duo/quad cpu's
-added microcode for 5100 5200 5300 5400 series socket 771 xeons (adapter mod required! see http://www.delidded.com/lga-771-to-775-adapter/ for more info)
-added ASUS bootscreen
-unlocked AHCI mode

Disclaimer: Use this bios at your own risk, I am not responsible for any damage this mod might cause your specific system

Can a moderator please move this topic from AMI bios unlocking requests to unlocked AMI Bioses?
