Power Management on Asus 1155 Motherboards

Asus locked part of their UEFI bioses, which results in a kernel panic when booting into OSX
The ways to sort this are to use one of these options:
1. use nullcpupowermanagement (also included in easybeast)
2. use a patched appleintelcpupowermanagement.kext
3. flash a modified bios
Using nullcpu is not a good idea as it means your cpu runs at full speed 24/7 and sleep will not work.
Using a patched appleintel kext means sleep and power management works, however after every update the kext has to be replaced (in the same way audio kexts have to be reselected). This can get annoying.
Flashing a modified bios only has to be done once
Using one of these roms means you won't have to use nullcpu or patched AICPUPM kext
These roms can be found at http://biosrepo.wordpress.com/
Consult your boards manual if you are unsure on how to update the bios
Note- Z77 boards must use the USB Flashback feature
When flashing any bios, there are risks that you may corrupt your bios.
If you are happy taking that risk, download the right rom for your board, and follow the instructions on the site.
Note- Windows is not affected when using one of these roms. The modification is small. Nothing is added or removed.
