I'm trying to downgrade it using this method here but it keeps telling me my BIOS isn't supported using the tool?

Massive thanks to brycv for hosting the files
brycv said:Thanks for the DSDT. Try applying the attached patch in DSDT Editor and see how it works for you. This patch includes all the normal patches and ALC892 so it will work with ALC8xxHDA and AppleHDA Rollback in MultiBeast along with a UserDSDT install.draken182 said:Here is mine for P8Z68-V Pro/GEN3 with the patched 3203 bio.

Speedstep works without NullCPUPM nor speedstepper, sleep/wake also (without PXHCD.kext) with matching DSDT.

Hi Francis,
Do we need SSDT to get the speedstep to work in Lion 10.7.4? Do we need to add DropSSDT in the boot.plist?
