I never touch anything else but the the whitelist removal, whenever i needed to tweak, i always told the guy who did on the specific forums to (ONLY REMOVE WHITELIST PLEASE!!) i don't want advanced menu and i don't need it and don't add it into my bios mod.I'll add a little cautionary tale to this bios mod encouragement ...
I swapped in a new i7 mainboard, so I read the bios, modded it, and wrote it back. It booted up OK, I hopped into Linux to redo the boot options and poke around to make sure everything worked. No problem. I buttoned it up, powered it on, and booted into OS X to a hang... the Intel graphics never came up.
Many hours later, I had an i7 T440s that could run Windows and Linux, but not OSX. I have an i5 laptop that can run them all (literally the same drive just moved back and forth between the two). I grabbed logs from both laptops booting up, poked at them, and was lost. I posted here (comment still awaiting moderation).
Then I figured it out.
"while I was in there" I used me_cleaner to disable the ME. The laptop wouldn't boot with the -S option (aggressive deletion), but booted up OK with the -s option (just flip a disable bit), so I thought nothing of it. While diffing the two logs, I noticed IMEI in the working one's log but not in the broken one. I associate IMEI with cellphones ... so I wondered if I just hadn't spotted a cell modem or something? Nope it's actually required for functioning Intel graphics on OSX. The me in me_cleaner is the ME in IMEI. So I undid the bit flip, and smacked myself for wasting an afternoon on silliness.
Having screwed around with bios modding, I'd recommend the whitelist removal and forget about the advanced menu (nothing too useful in there IMO), and definitely don't touch me_cleaner
Not because it removes something, that has never been an issue on my previous mods (L440 era) but that just opens you a lot of options to mess up your system, this is a laptop, it's not a spaceship or Drag Racing car to tweak things up to that extend where you don't even know what was the default value and what is the optimal one.
Yes, without imei you have no acceleration and that is only the visible thing on the surface, you have no idea what other mess happens under the hood.
Good thing you figured out and solved the problem.
