Hey all- just thought I'd let you all know there are a few new Gigabyte Bios updates to be had. I just updated the P55M-UD2 to Bios version F8.
If you happen to update your BIOS, let me know! I'm trying to keep MultiBeast and the DSDT Database current!
TO EXTRACT A VANILLA DSDT
Pretty much all you need to do is boot without a DSDT, and use DSDTSE to extract it. Then attach the file to this post. I'll then edit it and update this top post.
Step by Step.
1. Download your BIOS from Gigabyte's Website
2. Extract the .exe in Windows
3. Put BIOS file (about 2mb) on USB flash drive
4. Boot into OS X
5. Copy your DSDT.aml to desktop and Delete from /Extra
6. Install NullCPUPowerManagement.kext and LegacyAppleRTC.kext using MultiBeast.
7. Reboot to BIOS (Press DELETE at startup)
8. Update BIOS using QFlash Utility
9. Enter BIOS setup (CMOS Setup Utility)
10. Load Optimized Defaults (Very Important!)
11. Set SATA to AHCI
12. Set HPET to 64 bit
13. Save to CMOS
14. Boot into OS X
15. Download DSDTSE
16. Under Tools, choose Extract DSDT. The Editor will open with your DSDT.dsl all ready to edit.
17. Save that file as the name of your board and attach it here. (GA-P55M-UD2-F8.dsl)
Thanks in advance- updating is probably a good idea with these early versions of the P55 boards. There are some kinks to work out.
