Do I need Windows and AIDA64 to do this?
Can I do this on Mac OS X using IORegistryExplorer or something else?
Display Sleep doesnt work so I hope putting Vbios into DSDT will help
you only need ioreg... terminal code:
AMD/ATI BIOS ROM (may have to replace display with GFX0 or similar)
Code:ioreg -arw0 -d1 -n display | xpath '//key[.="ATY,bin_image"]/following-sibling::*/text()' | base64 -D -o ~/Desktop/vbios.rom
then, copy the generated rom into /Extra and rename it, i think it is like:
if you got
Vendor: ATI (0x1002)
Device ID: 0x6738
then, file name will be:
and to inject you need to add into boot.plist
I don't know for sure if it is done this way... If this does not work, ask someone else how to inject the vbios.
You can also try EvOenabler if nothing works..
