Good news!  I've been able to consistently boot from the HD using USBBusfix=Yes and GraphicsEnabler=Yes.

USB keyboard and mouse are working as well as my external HD.

I've been trying to fix graphics/audio etc...

So if I'm understanding this... I mount the EFI partition on my USB stick and replace the Clover/ACPI/Patched/DSDT.aml with the 10.10 version?

So I got past the black screen thanks to enabling Optimus.  The BIOS is A07.

It has Intel HD4000 and Nvidia NVS5200M.

Here's the result when I boot from USB: 

I made the USB installer and now I have it done with the proper e6530 bootpack, but every boot option I try only results in a black screen shortly after the Apple logo appears while booting.  I can't even get a screen using verbose mode.  So both the USB stick and HD install will not boot.

It's so exhausting at this point, I even got to the installer but the mouse/keyboard wouldn't respond.  I feel like it would be better to start over, but if anyone has experienced this please help!

Thanks.
