I gave your DSDT a shot and still same results. :-/

Now I am having a fully functional hackintosh on my T420 (4180-AH4) using the attached DSDT, you may check it out.

Thanks, however I had already added the dual link patch to the DSDT that I posted above.

If you could test it out for me and let me know if it works for you then I could at least rule that out and then I would know if I need to change the boot loader or something with the kexts on the system.


I have already tried yours and it didn't work for me, got me a black screen after booting, maybe you can try the DSDT i posted earlier, but still I am having some troubles about it, always get a self assigned IP and static IPs are not working

Any ideas what is wrong here?
t420 Intel graphics, no discrete adapter.

Using BIOS 1.37 whitelisted modded BIOS with modded DSDT.

Verbose boot ends with:
Transcript Offline - Buffer Pool Allocate Failed [181000]
DSMOS has arrived
macx_swapon SUCCESS

It _does_ complete the boot as I can hear volume changing from the speakers, I can blindly log in and I can even reboot by pressing Power 'r' Enter.
So I know its not frozen. The graphics ID is 8086 0126.
I have tried with and without all AppleIntel* kexts on the system.
I have tried with and without graphicsenabler=yes / no
I have tried PCIRootUID=0 /1 /2
I have tried DSDT with only RTC fix applied.

If anyone cares, I have also attached my DSDT for reference.
I changed the name of the graphics device to GFX0, removed references to cores that I dont have.
Matched the other Madl0n mods that he posted in another dsdt for the t420.


Hi Ludacrisvp,

You can check this URL: http://www.tonymacx8...a0f00229b33ce1c for more details about your issue.
It seems we both have the same configuration, I passed through this step, and used an already modified dsdt (in the above post) but causing another issues

I would prefer if you can patch yours to include the dual link fix, and please report back if it's working with you

Hello,

I have Lenovo T420 "4180-AH4" with the following specifications:
- Intel ® Core™ i5-2520 M
- Only Integrated HD 3000 "0x0126"
- Ram DDR3 4GB
- Intel 82579LM Gigabyte Network Connection

I managed in installing Lion (10.7 - Then updated with Combo update 10.7.2) on my external HDD WS "250 GB" formatted in MBR.

When I have used the attaced DSDT file in the initial post and it cause the screen to be black after the booting "Dual Link-Backlight" as described in the link below , but I think network was working fine, so I used a patched DSDT file found on the internet and now display is working fine but with these issues
- Enthernet is now connecting but fail to obtain intenet connectivity "DHCP-Manaually" - EthernetbuildIn used in start up - Kext AppleIntelE1000
- The battery/AC is not recognizable by the system

Also I am having another trouble installed XCode, it says you have to upgrade to Mac OS 10.6.6, Altough "About Mac" says that I have version 10.7.2

I have tried to edit the DSDT file but I am not that experienced enough to do so :((, so if someone can help me about it, that would be GREAT.

The used files are attached, I need to compine the two 2 DSDT files, so I can use the one in the initial post but contains the fix for dual link as described in the above link.

Thanks a lot.
