Forgot to attach, sorry

I did one by one BIOS upgrade till A06, on each iteration I tried the installer, the results were the same timeout. Then I took the latest update from Jake Lo, shutdown error is back and some acpi errors and CPU model is unknown, please find attached. Thank you,

it was A04 you mean upgrade one by one? I always thought that BIOS upgrades are cumulative so I can just apply the latest. Dells support site recommends me to install the latest (A10) BIOS only.

no more Voodoo? I updated BIOS to A06, still the same "IOGraphics flags 0x43". However no "Previous shutdown code: 5" and the system does not go to black screen, it just hangs. After a while it says "busy timeout[0], (240s), kextd wait(0): 'AppleACPICPU'. Then again "busy" and black screen... I checked BIOS, it says Video BIOS Version 2132v08, could you please tell me whats yours? Thanks a lot!

what boot pack did you use? Thank you,

yes, i tried 0X01660001-0X0166000B

Did that from Clover menu (Options/Inject Graphics), same error Could it be related to DVMT-prealloc ? Or DVMT-prealloc is a problem for Broadwell only? Thank you,

Not much of a luck (( Appreciate you effort, see attached Thank you,
