820-2914 no power

Medusa gives you error?
Don't forget to remove at least one of R8904/11, before power up the board.
Also, do NOT do PRAM reset.

Do not have cables to mod it at this time and customer needs back asap. Was hoping you could modify the file

 

[2informaticos]

Cables to mod what?
Don't you have A4064 adapter board?

I will try to modify the BIOS later...

 

[Kyle93]

No do not have A46064 adapter board but just ordered it. Only have Medusa and the TL866A at the moment.

Thank you for modifying bios when you get a chance. A4064 board will take at least a few weeks to arrive here in states

 

[2informaticos]

There are more good to have things, like A4069/70.
Tiresias GPU killer is also the best solution for actual problem.

 

[Kyle93]

Can you still provide moded bios?

 

[2informaticos]

Use this, for test...

With mod bios board boots to apple logo and loads but very slow when switching to intel graphics. Anything else we can try to fix the GPU vcore issue?

Discard software issue, booting USB macOS.
