Patching Precision M6700 DSDT/SSDT

[zachg]

Thanks Bronxteck.  I'll go through the ioreg dump tonight to see if I can pin down the primary display in ioreg.  In BootDisplay, I tried both 0 and 1, but no luck so far.  I'll try iterating through the number of ports (currently set at four?) to see if I can pin down the internal display.  Is the connector type for an internal display LVDS?  Also, do you have an idea of what to look for in ioreg?

[zachg]

So here's so excerpts from my ioreg.  I think they are relevant, but not too confident.

What I see is that there are four ports (0-3).  I think my external display is on port 3.  I have a feeling that the internal display is port 0, as port 1 and port 2 have a couple of similarities that aren't shared with port 0. I have no idea how to effect these values.  Graphics flags?  Clover plist addons?  I changed my BootDisplay flag to 1 to see if it mattered.  No change.  I also tried injecting my EDID and other display values with Clover.  No luck.    I'll keep trying.  I had a hackintosh desktop about five years ago and recall that persistence was the key.

I also added the readable version of ioreg as an attachment.  This is a copy paste from terminal, but clips the ends of a lot of hex values.

[Bronxteck]

yeah looks like apple boot display is on port 0 but it says display type is none yet port 3 is LCD so maybe try 3. if not it looks like you might need to patch connector types? i am not familiar with that part.

[zachg]

So, no luck yet.  I started all over at one point with a different clover version and made a note of every step I took.  Still can't get anything but a black screen on LVDS.  I pulled an EDID from linux, but no change.  I'll probably go back to linux until I have more time to tinker.  He he.  There's some irony in there some where.

Any luck with your m6700 yet?

What BIOS version does your m6700 have?

 

I have got m6700 with i7-3470qm + HD4000 + k3000M, BIOS A18. Unfortunately, having graphics glitches right now after updating the BIOS from A10 to A18. Shall I downgrade the BIOS?

 

I am looking for a DDST that works with my hardware...

[Bronxteck]

it might be the same bios glitch issue as the E6X30 series. that machine glitches after bios A11 or A12 you have to downgrade bios to I think A03 then back up to A11 or A12. its documented on the site somewhere.

[antrieb]

all right...yes, the issue was related to the high bios version. I downgraded to A12 -> no more graphic glitches ever since.
