[Trucker MK]

Anyone?

[nai22]

hi trucker,

 

thank you for the dsdt. now everything works sleep, graphic etc. i couldnt test the 10.7.4 kext, cause my brother did a timemaschine-restore back to 10.7.3. i will try it tomorrow. thanks again for your help. I will show my gratitude

[Trucker MK]

Hi nai22, I'm glad i helped. I'll pm you after 10-12 days. I'm on vacation now.

You asked for some help. I'm still waiting for your DSDT and VBIOS.

Hi trucker MK , i have your same videocard ( Radeon HD 6650M 2gb), and before 10.7.4, the kext work. i have downloaded ATI6000Controller.kext and your dsdt for the 10.7.4, but i can't patch IntelCPUPowerManagament: is necessary to patch or i can use the same patched 10.7.3?

[Trucker MK]

It's simple, just run the script with su, try again, I don't have 10.7.4 ATM, maybe someone else would like to share patched 10.7.4 AICPUPM.kext?

Many thanks, with 10.7.4 the amd 6650m works .. unfortunately, all the kext for the wifi ( AR5B97) seem to not work with OSX 10.7.4

How can I get a VBIOS dump please?Is post #92 my vBIOS dump?

You are welcome, I don't have kexts for wireless, the solution for me was to switch the wireless adapter from my old laptop, it has native OS X support.

Hi all,

 

I have been trying to make my ATI Radeon 6650M work on my Acer 7750G laptop. I have the model with identifiers 1002-6741 and subsystem 1025-050F (and not E).

 

Unfortunately, I am not able to dump the Video bios... I have tried to use the following:

 

- ATI Tray Tools, with low level driver installed (Windows 7 64bits) - does not find the Catalyst driver

- GPU-Z (Win7 64) - does not work

- AIDA64 (Win7 64) - dump the BIOS of the Intel HD 3000 instead

- ATI Winflash (Win7 64) - does not find the card

- RadeonDump with RadeonPCI.kext - cannot be used on Lion 64 bits

- RadeonDump without RadeonPCI.kext - does not work on the ATI card. When the graphics card is set to "Integrated" instead of "Switchable", it dumps the Intel HD 3000 BIOS.

- Downloading the most recent BIOS (should include video BIOS according to notes) from ACER - radeon_bios_decode does not find anything on the two binary BIOS files

 

I am looking for a solution, if by any chance someone was confronted to the same problem. For now, I am using the integrated HD 3000 card, with glitches that I could not completely solve...

 

Thanks for any info !

Hello, I have an ATI Radeon HD 6470m id and subsystem id 2001:1043 and 6760:1002 i have the same problem of black screen even when it is recognized, you can help me because I knew nothing about what should I do? I attach a folder with the extracted files from windows with AIDA64 and another folder of chameleon with dsdt extracted wizard, I only have one video card.

Search Google for Phoenix BIOS Editor ( you can also edit Insyde BIOSes with this tool), and for howto. In general, you need to extraxt the bios, you will get a lot of *****.rom files in a separete folder. The one you need is around 64 KB, select each file with that size and open it with RBE (Radeon BIOS Editor). There are more than one VBIOSes in the main BIOS, look for the right one.

Attach here your main BIOS and screenshot from GPUZ.

[beboppp]

Phoenix BIOS Editor did not work in my case. Here is how I was able to extract the video BIOS.

 

On Windows 7 64 bits:

 

1) I updated to the latest BIOS from Acer website (BIOS_Acer_1.20_A_A.zip), using the FLASH utility for Windows.

2) I used Universal BIOS Backup Toolkit 2.0 to extract the BIOS file Acer-V1.20.rom on Windows 7. Run as administrator as requested.

3) I took the screenshot with GPU Z. You can see that the video BIOS is not detected properly.

 

On OS X:

 

4) I downloaded scanlzma.c, fvdump.py, fsdump.py from http://marcansoft.co...ds/insydehacks/ . The link was provided by http://www.mattday.n...ng-insyde-bioss.

5) I compiled scanlzma using "gcc -o scanlzma scanlzma.c", and added the x permission on scanlzma, and the .py files using chmod +x.

6) I decompressed the BIOS using "./scanlzma 0 < Acer-V1.20.rom | lzma -c -d > acer.rom" with the error message "lzma: (stdin): Compressed data is corrupt". I disregarded the message, a file "acer.rom" was produced.

7) I extracted the firmware using "./fvdump.py acer.rom", with the following output.

Firmware Volume at 00000010

Reserved boot zone: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00

GUID: d9 54 93 7a 68 04 4a 44 81 ce 0b f6 17 d8 90 df

Size: 0x780000 (data 0x77ffb8)

Attributes: 0xffff8eff

Revision: 1

Blocks:

3: len 0x280000

Dumping to fv-00000010.bin

8) I dumped the filesystem using "./fsdump.py fv-00000010.bin".

9) To find the relevant .raw file containing the video BIOS, I used the command "for f in *.raw; do echo $f; ./radeon_bios_decode < $f; done"; "radeon_bios_decode 2.0" was placed beforehand in the current directory.

 

The two files that correspond to the peripheral ID are:

The files are attached to this post, with the GPU Z screenshot and my original DSDT file. Please advise me if I need to make changes to the PEGP section.

 

I hope that the procedure above will save time to other forum members! I had to do quite an exploration to make it work.

[Trucker MK]

Check this video VBIOS_dumping.zip

 

Things you gonna need:

 

1. Phoenix Mod Tool v1.42 http://www.sendspace.com/file/mbfyzi (To extract the BIOS)

2. Radeon BIOS Editor (RBE) http://www.techpowerup.com/rbe/ (To identify the VBIOS)

3. RW Everything http://rweverything....t/download.html (To generate RW file)

4. Latest BIOS for Acer 7750G http://support.acer....=1&modelId=3476

 

Note!!! There are more then one VBIOS rom files in the DUMP folder ( the size is about 63-64 KB). Use RBE to identify yours. Compare data between RBE and GPUZ or AIDA64.

Hello Trucker,

 

Have been reading here with interest.Have Acer 7741g with i3 350m and ati 5470 .

Have everything working in 10.8 except lvds.

Have edited dsdt at gfxo and pegp but made no difference.

Have edited connectors using radeon bios decode info, force edid , chimera,chameleon.graphics =yes & no

Its possible my lvds is same as acer 7750 ?

.Only need dual link patched.

I have just downloaded the pegp.dsl from here to see if it can help with my edits.

Could you take a look at my dsdt ,since it may be similar to yours?

 

Thanks. Úll Mac

Dobro jutro, Trucker MK

 

Do you know how I can get my 6770M working?

AMD Radeon HD 6770M 4095MB [1002:6740] (subsys [103c:3388]) (Turks) :: PciRoot(0x0)/Pci(0x1,0x0)/Pci(0x0,0x0)

 

This is my system:

Intel® Core™ i7- 2670QM Prozessor [4x 2,20 GHz]

AMD Radeon HD 6770M + Intel HD 3000

 

Both video cards are recognized but only the Intel3000 is working and there is no way I can turn off the Intel card in the BIOS and I also cannot flash the Bios -> stupid HP.

 

I hope you can help me.

if you can't block your hd3000 in bios,you'd better give-up using your ati card,and mod your hd3000 to work better

I don't have any experience with switchable graphics and HP. Have You looked for a moded BIOS for your laptop model? But be careful!

Hi all,

could you help me installing those kext for my Radeon HD 6550m please?

i've tried compiling DSDT but i'm definetely not familiar with this.

 

This is my configuration

Hp Pavillion dv6-3322el

Ati kext attached.

 

Running Mountain Lion 10.8.0 ati 5470 is 512 mb

Not sure if it makes any difference but dsdt was extracted from win7 with aida 64 .

 

With graphics enabler =yes can confirm eulemur buffer loads with vga connected

Based on the connector outputs I came up with

 

LVDS 02000000 40000000 0901 0000 10 00 00 07

HDMI 00080000 00020000 0001 0000 11 02 01 02

VGA 10000000 10000000 0000 0000 00 10 02 01

 

but no lvds .

Mountain Lion 10.8.0 from app store installed on empty hdd with ###### + laptop support

then ###### with chimera , 8.1 mac book pro , evore boot , fake smc , with and without voodoo hda 0.2.1

 

With chimera g e= yes Card recognised as ati 5400 series thru vga --- no lvds

Hey macsane123.

How could I mod the Intel3000?

 

Question:

But can't I just tell OSX to not load the Intel3000?

Maybe by deleting its kexts or writing something in the Bootloader.
