I made the USB drive with MyHack and put the Extra folder from this site for the M4300 and all seemed to go okay.

 

I booted from the drive with -v and all my components seemed to be listed correctly. It got to the point where it usually goes to the Installation screen, but the display went black and stayed black.

 

What changes do I need to make to the Extra folder on the USB drive?

 

 

Specs: nVidia FX360M card and 1920x1200 resolution, bios A15. I used all the Bios settings that someone (Herve?) listed in another thread for the M4300.

 

I previously had Snow Leopard installed and it worked fine.

Update: I replaced the dsdt file in the Extra folder I downloaded here, with the dsdt from an Extra folder that someone uploaded in this Forum to help with the M4300 (Herve?).

 

Anyway, the M4300 finally finished booting from the USB disk and I am now installing Mountain Lion.

 

Will keep posted.
