Hi theconnactic,

Thank you anyway!

 

Unfortunately, patching the AGPM wasn't enough for me.

 

All the best!

I tried your hex edits (both versions) to enable the VGA port for a hack i'm setting up (i7 3770 + GA-B75-D3H), because the monitor is VGA-only (i'm using my TV plugged via HDMI to boot to desktop, but this is a temporary solution). What i got up to now: 

 

1) With GE=Yes and the edited frame buffer, the boot hangs in the Apple logo phase, exactly at the point the desktop should appear - the spinning pinwheel stops but the screen doesn't go away. With the TV also plugged via HDMI, the VGA monitor gives a garbled and unusable output, but the TV outputs fine at 1080p (even though i set graphics mode to the VGA screen res). Here's an IOReg: attachicon.gifIOREG1.zip

 

2) With GE=No, this DSDT loaded - attachicon.gifDSDT.aml.zip - and the edited frame buffer, the very same result. Here's another IOReg: attachicon.gifIOReg2.zip

 

I really need the VGA output to work, since it's unfortunately the only featured port of this computer's monitor. Any help pointing me to the right direction will be much appreciated.

 

All the best!


P.S.: all the IORegs were made using the hex edit version 2, but i got the same outcome with version 1.

 

What I've noticed is that the latest Framebuffer kexts DO NOT support VGA with the provided binary patches.

 

The old 10.8.1 (and older) support them; if you need the old framebuffer kext send me a PM.

                        }
                    }, Local0)
                DTGP (Arg0, Arg1, Arg2, Arg3, RefOf (Local0))
                Return (Local0)

 

These are the existing values​​.

Can you send me the old Framebuffer kexts please?
