This is for the ASUS Maximus III Gene motherboard. It's a P55 based motherboard with extensive overclocking BIOS settings.
This one improved upon the current one in the database because:
1. Sleep mode works!
EDIT: To clarify, the current DSDT will not allow the system to enter sleep mode (S3). This one will not only allow entering Sleep mode S3 but will also allow resume via a USB keyboard/mouse.
Do yourself a favor and use MultiBeast (awesome tool tony!!). I used the latest as of now (2.1.4) and you should select:
- UserDSDT (and pick this dsdt file)
- System utilities (all sub-items)
- Audio voodoo HDA official 0.2.2
- Disk (IOAHCIBlockStorageInjector and all 3 JMicron ones)
- Network Realtek R1000SL (for entire RL81xx family)
- smbios, pick any *one* core i5/i7 setting (doesn't matter if it's "imac" or power mac; with those if you really have an i5, select i5. If you really have an i7, select an i7)
Since I've a Radeon 5770, I had to also select (don't skip any of these 3 - your system will not boot!!)
- ATI 5xxx support (advanced options -> kext->graphics->ati)
- ATY_Init Vervet (advanced options -> kext->graphics -> enablers)
- com.apple.boot.plist "32-bit graphicsEnabler = NO"
