Yes the DSDT did have edits for Audio. mald0n edited the DSDT for L502x.








thanks for the info markmac81, yes the guide does need an update


Not sure how it worked when you did it, but I had to do step 11 twice, once according to the guide, then again after the 10.6.8 update.

Also, what kext enables the sd card reader?

I did not have to do it twice. I wonder why. I did not reboot until all the steps were complete after applying 10.6.8. Is it possible that you were using the new version of 10.6.8?

I do not have the card reader setup. It is a Jmicron card reader (JMB389) per dell's driver download.

I remember reading a thread about Jmicron card reader, let me see if i can find it.

Sorry, have not had much time to try these. Please report if you get them working.
thanks

I don't have a Dell XPS L502X but I do have a Intel Core i7 SandyBridge 2630QM and I'm trying to get the integrated graphics running. How would the steps differ from yours? Do I need a different DSDT or just not use one?



The guide should work for the most part. Skip the DSDT steps.

To get native resolution, you do not need a DSDT.

But lots of other devices will not function without the DSDT. reach out mald0n for help with DSDT via hist DSDT thread.

I followed the guide - step 12 says to reboot, before applying the 10.6.8 update, I guess that would explain it.

I'll try the sd card things when I have a chance.

Thanks for the guide, I got it working. I'm only missing audio, ethernet, and wifi. My ethernet and wifi devices aren't supported. I will probably get a wifi card if I can. Anyone have any suggestions (one with bluetooth would be nice)? Also, Voodoo seems to glitch my audio for some reason (It routes my built-in mic to my speakers). I'm not sure what I should do about that.

Hi
Thanks for the guide
I followed your instructions to install Snow Leopard on my L502X.
Everything went well until I finished step 18 and rebooted,
but after reboot I get the boot0:test and boot0:error message.
I tried installing the bootloader manually, but I get the same problem.
Can anyone help me out?

Hi wen1,

I got audio working with your kexts, stable, no distortion, but the quality is not good, sound like mono. I have to use BOOM.

I don't know if AppleHDA kext affect the audio quality, and the IOAudioFamily kext as well.

The driver at the following link has better quality (with AppleHDADisabler) but with background noise and sometimes it causes kernel panic.
http://code.google.com/p/voodoohda/

Is your sound quality good?

@wen1,sybexs,steverings...

hi guys,
finally i got to the point that i can boot into 10.6.8 (on my l702x with 3D),
but to get there i had to install the kernel from bridgehelper2.1 and had to replace AppleACPIPlatform.kext and IOPCIfamily.kext after updating to 10.6.8.
all the rest i used exactly wen1´s guide.
But now the Nvidia Card (555) dont work (only 1024x768,3mb vram)and also in hardware profiler it says System-Bus Speed is 400Mhz,but the cpu is right.
Does anybody have an idea,could be the DSDT causing the problem?
If i boot with I-Boot legacy it comes up in 1920x1080.
Soon as i use ##### and DSDT it wont work.
I would really thankfull for any idea,since im trying for 2 weeks now to get this to an end.
I attched pics of the hardwrae profiler showing the graphic status and the 400mhz issue!

Thanks a lot guys for your help!!!!!!

Are you using your own dsdt or the one supplied in the first post? When using a dsdt it is always good to generate your own in windows and then make the edits necessary to the dsdt to make it work properly.

To get the 555M working use http://www.tonymacx8...pdate-2.0.0.zip. I believe everything works including QE/CI with that installed. I havent tried the hdmi ports tho. One thing i am still having problems with is the audio. No matter what i do i can not get sound to work.

When you get your DSDT properly edited things like bluetooth will be enabled (depending on card). What are the complete specs of your laptop? I have the 17 hd i72720 with gt555m and 16 gig of ram. Also are you booting in 32 or 64?

hi sybexs,
thanks for your answer.
yes i was using the dsdt from wen1,which i think is made for the optimus,problem is i have no idea how to edit the dsdt in the right way.
im using the dell l702x with gt555m with 3D,cpu is i7 2720.i use 2 hdd´s and the intel advanced 2630 (bluetooth is working on this).system is running in 64bit....so seems we have the same xps,is yours 3D?
if you could help me with the dsdt i would be really happy!
sound worked after the 10.6.8 update but i had to go to the audio settings and had to select the internal speaker,by default its set to digital...i guess you checked that but just in case you didnt you should have a look...in fact i thought it didnt worked for me because normally its set to internal speakerit wont change to headphone automaticly if you plug in one.

maybe i will send my dsdt to the guy wen1 mentioned,hope he can help.but if you have an idea please let me know.

btw,which kernel you are using and did you made a benchmark with Geekbench??mine is showing around 7300 points,it should be at 10000-11000.would be interested in other peoples benchmark results.
im not sure if the kernel from bridgehelper2.1 is the best one,but its the only one working for me!

Thanks and greets kai

btw. the system-bus speed issue (mine shows 400mhz) seems a "bug" in chimera as they say here:
System Bus Speed Issue

Hello rawbkk,

Your system has 3D, which means it does not have optimus. Just patch a new DSDT (ask MaLd0n) and install like sybexs said and all should be fine.

About the kernel in bridgehelper2.1, I think it is more stable than one in 10.6.8.

Hey guys,

Thanks a lot for this awesome guide! I wanted to know if the sleep issue has been solved. That is the only thing holding back my full switch to os x on my L502X.

Thanks.

rawbkk,

A custom DSDT for your laptop is the answer to most of your other problems. REach out to mald0n for help. He is a great guy and responds very fast. I will link the thread here in a minute
http://www.insanelym...p...523&st=3820

use this to generate the files first and then reach out to mald0n via the first link
http://www.insanelym...p...st&id=81816

For the nvidia card, you just need to get the right nvidia driver as mentioned by sybexs earlier.

Sound quality is not great but is definitely usable. It is kind of boomy and missing on the high frequencies.

The DSDT in the fist post is purely for the L502X. I will add a note for that effect.

Also, if you do get a DSDT created and share it here, i will add it to the first post.

Sleep still does not work properly for me. I have seen some kexts posted by folks on other thread. Please share if anyone come across something that fixes sleep.

@wen1

thanks for your answer!

im using the tonymac nvidia update driver and it works fine as long as im booting with ##### legacy without dsdt,i think here is the problem...so nvidia works fine just need to get the dsdt sorted out,i was sending it just before to MaLd0n.
i will post it here when i got it to work as well as the steps different from your guide so people with 3d/no optimus can use your guide.
sound is fine for me,the boom thing made it even better but in fact for me quality is not that important since im using an external card for music production,but the boom programm with right eq settings made the sound much better.
here is a link for that tool:

Boom 1.1 Sound Improver for Mac

for sleepenabler you may try this one...i think there was one guy with l502x saying this one worked for him on 10.6.8,but i couldnt try it so far since my system is not running 100%,if this one doesnt work im sorry ;-)!!

Sleep Enabler 10.6.7

Thanks also to dxluong and sybexs for their help!!!!!!!!!!!

and of course to everybody here helping other people out!

hi sybexs,
thanks for the DSDT...unfortunately it didnt change anything,still no nvidia graphics.i did install tonymac nvidia update again but same result.
but you have the 3D version right???strange that it doesnt work but as i said if i boot with ##### legacy nvidia works.
i will wait for the other guy,hopefully he will find the problem.but thanks anyway!!!

I have to admit, I have been lazy and have been using the legacy cd and have not setup mac on a mbr. I will do it this weekend or tonight matters on workload. I suspect this is probably why i cant get certain items to work through the dsdt.

I do have the gt 555m HD version with 3g video ram. I have to double check the dsdt to see if i included the edits for the video card. you might also want to try the NVenabler from the ##### cd along with the kexts from the tonymac zip. The other thing you might want to try is the install of the new cuda drivers for os x. Some of the kexts might need to be edited with your device id to get working properly.

The video edits require an install of osx with the ##### cd and working video to pull info from the IORegistry.

Install Procedure Dell XPS 17 L702X with 3D Graphics

@wen1,sybexs

got 10.6.8 10k524 fully working now!

here are differences to wen1 guide for l502

just follow wen1 guide but after installing 10.6.8 update you need to run tonymac BridgeHelper 2.01 !!!
the kernel included there is the only one working for me.
then go on with #####,install with same options except you need to check boot options: GraphicsEnabler=Yes/64bit Apple Screen

then native resoltion works as well as sound and all usb!

only thing is still the low benchmark i get.
trying geekbench 64-bit my i7 2720 gets around 7700 points,it supposed to be between 10000-11000

can some people posts their result??

im still waiting for the modified dsdt from Madl0n which maybe bring some more imprvements.

good luck to everybody!!!

@wen1
maybe you could ad this to your original post...and also id like to ask you if you changed at any point the kernel bbecause i dont really understand why only the 3d version needs the different kernel,specs of l502x and l702x are nearly the same except non optimus.couls this really cause the kernel panic??

@sybexs
i think you could give it a try now to install with chimera,i think should work for you too and sound will be working then...i would be still happy if you have ideas to improve dsdt

thanks and greets kai

ehi, l702x too, 3D ;D

in your guide you forgot that we need to backup AppleACPIPlatform.kext and IOPCIfamily.kext before the combo update (10.6.8), and then replace the new ones with the olders.
This is necessary to avoid the PCI error @reboot.

hi jumo,

thanks and sorry,you are right,you have to back up those kexts (from 10.6.3 install) and install + repair permission before you restart.
one question,which kernel you are using?? also the one from sandybridgehelper??
did you made any benchmarks since the cpu nad whole system performance is only at about 70% with xbench and geekbench...thats the only thing which i would like to have improved!

yep i'm using the sandybrirgehelper because it's the only one that works,
i can't do a benchmark because i still need to boot with ##### legacy, without the PC can't find the installation
I had grub installed before and i think i need to reinstall it, or find someway :\
