mattrowe Posted June 2, 2014 Share Posted June 2, 2014 Hello all, So finally i have managed to edit my DSDT to allow the 7970M card to be enabled. I have the HDMI working 100%, this is great but as it is a laptop i would love to have to internal screen working. I have read every forum on the net on how to edit custom personalities but i just can't seem to understand it! My laptop is a Alienware M17X R4, the ports from the card are: Internal screen, HDMI, VGA, DP. My frame buffer is Buri. I understand i need to inject these ports into the frame buffer, i just don't understand how to do it. I have looked everywhere on how to do it, and i have found articles that physically show me how, i just don't get it. So any help would be awesome!! If you ned any dumps, extra info tell me and i will get back to you ASAP! Cheers!

applehacker Posted June 20, 2014 Share Posted June 20, 2014 you will need to hexedit the ati7000controller and look for existing hex values, and replace accordingly. rampagedev has a pretty good breakdown: http://rampagedev.wordpress.com/kext-editing/editing-atiamd-framebuffer-personality/ So we take connector 0000000 and split it up (the first connector) 02 00 00 00 00 01 00 00 29 05 01 00 10 00 05 05 And divide by the last two parts again, by two, giving us the divided Buri personality: 02 00 00 00 <-- Connector type 00 01 00 00 <--ATY control flag 29 05 <-- Features 01 00 <--Unknown 10 <--Transmitter 00 <-- Encoder 05 <--Hotplug ID 05 <--Sense ID Now we start modification based on the data: 02 00 00 00 <--Leave this alone, we need this for LVDS 00 01 00 00 <--We have two options here, 0x0040 or 0x0100 which would translate into 00 01 00 00 or 40 00 00 00 (after byte-swapping, I believe) 29 05 <--Features...this is where it gets tricky....I would try 09 01 because lvds/backlight (not sure...somebody else double check for this) 01 00 <-- leave aone 10 <-- you have "INTERNAL_UNIPHY"...so I would try 00, 01, or 02 here 00 <-- I would guess leave alone or try 01 or 02 05 <-- would leave alone or change to 00 or 01 05 <-- I would guess this is correct In addition, you should inject your EDID via clover or DSDT Will take a lot of trial and error I have tried these two so far, no success: 02000000400000000901000000030005 02000000400000000901000010000005 Link to comment Share on other sites More sharing options...
Rikoshet Posted August 11, 2014 Share Posted August 11, 2014 Ok, I'd like to contribute! I have internal lcd working ok after sleep and wake, otherwise I've banding like this: http://www.insanelymac.com/forum/topic/291117-how-to-make-radeon-desktop-or-mobility-be-working-by-using-clover/page-3?do=findComment&comment=1976199 So I'll comment what applehacker wrote: 02 00 00 00 <--ok, no comment here 00 01 00 00 <--With 0x0100 (00 01 00 00) have black screen, with 0x0040 (40 00 00 00) it is ok 29 05 <--I've tryed 2905, 0105, 0805, 0101, 0801-does not change enything 01 00 <-- from guide this must be 0000 for this entries you must use redsock_bios_decoder! 10 <-- you have "INTERNAL_UNIPHY"...so I would try 00, 01, or 02 here 00 <-- I would guess leave alone or try 01 or 02 05 <-- would leave alone or change to 00 or 01 05 <-- I would guess this is correct so in my case the string is: 02000000400000000901000010000005 Let me know!
