LVDS on mobility HD4330 framebuffer edit.

Whaka · May 7, 2014

Hi

i try to make working this chip under 10.6.8 (clover as bootloader) on acer 4810TG laptop.

i short the story...

QE/CI work fine, hdmi work fine (as extened desktop), vga work fine (as extended desktop too)

after hours, and hours of test i can't have the lvds working, i only get a black screen (backlight work)

but, the screen himself is well detected as primary display, as hdmi and vga can work as extended desktop.

so, i think it's a bad routing, but i don't know where...

i follow this tutorial : http://www.insanelymac.com/forum/topic/252061-mobility-radeon-hd-4650full-resolution-with-qe-ci-working-on-internal-lvds-screen/?do=findComment&comment=1655903 and using the "old method"

here is radeon_bios_decode result :

Connector Object Id [5] which is [VGA]
encoder obj id [0x15] which is [INTERNAL_KLDSCP_DAC1 (osx txmit 0x00 enc 0x10?)] linkb: false

encoder obj id [0x1e] which is [INTERNAL_UNIPHY (osx txmit 0x10 [duallink 0x0] enc 0x0)] linkb: false

so, as in the tutorial, i use the defaut personality "shrike" and patching it. (i tried with "flicker" and "gliff" too, no succes)

first, i need confirmation.

is this path really correct for lvds (i have a doubt about encoder) ? :

transmitter : 12

encoder : 00

hotplugID : 00

senseline 07

edit : i tried with the encoder set to 04, it's not better.

i forgot to mention, this laptop also has a gma 4500mhd, but is disabled in bios. this could have importance for the primary display anyway ?

Thanks for your help

As I see from redsocket dump encoder=4 for LVDS

Connector Object Id [14] which is [LVDS]
encoder obj id [0x21] which is [INTERNAL_UNIPHY2 (osx txmit 0x12 [duallink 0x2] enc 0x4)] linkb: false

got it !

it was not 04 as redsock return it, it was 01...

and i forgot to turn off dual link in clover, that's also that wich stuck me a moment.

so, all seems to work now, with a little bug : the apple in the finder bar is green.

you have an idea about that ?

thanks

hey. i've heard that the apple turns out freen if you have just poor qe/ci support (i've seen this behavior with intel x3100)

could you please explain you're steps to get this thing working? i don't want to open a new topic (for now) but really want to get this card to run.

I have got a MSI CX700 Notebook, which i would like to use as a scanner/printer-server , webserver , fileserver and airplayserver (especially the extended screen function). exept airserver everything works fine (airserver crashes with error 101 (due to missing graphics accerleration i guess)

Therefor i connected 2 3,5 hdd with externat power supply to it. I still use the original lvds Display. For Network i use a ExpressCard with realtek 8111 chip and 1 gbit which works fine. Sound works fine with USB-Soundcard.

GOALS:

1. get airserver to run @ native resolution (1600x900)

2. get full graphics acceleration (but i think it is needed for 1.)

3. abiltiy to turn off screen

what i did so far:

get my device id: 95521002
id is in info.plist of radeonx2000.kext
write id in info.plist of ati4600controller.kext
switched from chameleon to clover as bootloader
added vram, injectATI, fakeid (0x95521002) to boot.plist
tried Gliff, Shrike and Flicker as Framebuffer. but everytime i get grey screen which turns into black after about 5 minutes
i was unable to extract vbios with atiflash/gpu-z/winflash/RBE but found Vbios of hd4570 (which is basicly the same chip but higher clocking)
extracted edid and display-registry-data from windoze
saved ioreg output
stored 4570.rom as 1002_9552.rom in /EFI/CLOVER/ROM/ and use load VBIOS option

i am a bit lost now, since i did not understand the editing of the framebuffer completely (read rampagedevs guide) and cannot extract my bios.

Pictures:

About this mac with Card injected but wrong FakeID (to start to desktop without safe mode)

How the screen turns out after ~5 mins (also tried to connect external Monitor via VGA. same error there):

These are my edited kexts, the ouput of ioreg and the 4570mobility bios (renamed as 1002_9552.rom : http://www.file-upload.net/download-8906947/4330files.zip.html

I hope you guys can help me!

EDIT:

after updating my bios atiflash tells me:

No VBIOS, Flashtype Unnown SPI (64KB).

but i got the complete Bios for the mainboard (which should also hold the vbios then, right?)

Greetings!

i was unable to extract vbios with atiflash/gpu-z/winflash/RBE but found Vbios of hd4570 (which is basicly the same chip but higher clocking)

I'm sorry. You're wrong to assume the 4570 rom is 'similar'.

The rom itself tells you, well put it roughly, what port is used for the connections, and those change the framebuffer edits. PM me, I might be able to help.

could you please explain you're steps to get this thing working? i don't want to open a new topic (for now) but really want to get this card to run.

sorry for the delay...

you probably just need to do what i did.

if you follow the topic i linked, you should be able to understand how to edit your framebuffer. the procedure is not so different since snow leo/lion.

first, to work with your vbios, if your clover is installed in ESP, or on a fat32 partition, you can use it to extract the rom, pressing F6 at the clover screen,

it store it in the misc or ROM folder as 00000.bin (or someting like that, i don't remember exactely)

ashindnile · May 28, 2014

Oh i think he's past that issue

I asked him to use AIDA, but yeah clover+F6 works. You can get the c000.bin file in /efi/clover/misc

Whaka · May 28, 2014

i didn't see his new post at this moment, that's why

LVDS on mobility HD4330 framebuffer edit.
