No. Perfectly fine. However, as DoiX reported, youll have issues trying to sleep in OSX

Reflashing to A06 will solve that problem if you find it annoying

I got iAtkos L1 installed on my L502x now (same specs as AKennedy, except 4GB) I have a few questions.

1. How can I fix the startup of windows? Because I have missing BOOTMGR now. Can I just use these commands: BootRec /FixMBR, BootRec /FixBoot and BootRec /RebuildBCD?
Or does this break the boot loader? If so, what can I use to fix this?

2. My audio hardware isn't recognized when I open Audio/MIDI-configuration. It was recognized one time before (don't know if it was this install) but I don't know with which kextx that was or if I used both kexts. Can you use both kexts at the same time or do I need to delete one if I want to try the other one? And were do I need to delete the kexts? Here? /System/Library/Extensions

3. I have the idea my Kext Wizzard isn't working properly anymore. In the beginning it selected automaticly my OS X target disk. But now it say Choose and I can only choose between Choose / Item 2 / Item 3. How does this come? I downloaded it again from the forum topic of (http://www.insanelym...howtopic=253395 newer?) and it works again!

Thnx for the great TUT!

EDIT: All is working great except the dual boot with windows. I can't get Windows 7 to boot up. I tried the three commands listed above but that doesn't solve the problem. I also tried the automatic startup repair with windows 7 but also that doesn't fix the boot. And I tried the following commands what also doesn't work for me:
bcdedit /export C:\BCD_Backup
c:
cd boot
attrib bcd -s -h -r
ren c:\boot\bcd bcd.old
bootrec /RebuildBcd

What can I do to make it work? I need my windows too.. :(

Owen, when you need to install the kext, try the package from DoiX first. Youll Probably get an error saying the kext were improberly installed, but just run kext utility an Disk utility and reboot like normal. I'll update the guide sometime later this week when I get a chance. Good luck on installing

What can I do to make it work? I need my windows too.. :(

I had the EXACT SAME PROBLEMS except 2nd one, Solved the 1st problem, 3rd one skipped as I used drop kext software
1st time I tried on my system, the boot loader didnt work, rest all worked. So I decided to format everything and start from scratch.
1.Install win7 drivers etc.
2.Install Mac follow the guide
and magically the bootloader works without a hickup!
Anyway Back to the topic, I made the win 7 partition active http://www.tonymacx8...1&view=previous
Then when I tried to boot same error as yours, so I tried to select the 100MB System partition and Vola it booted into Win7
I tried all 701, 502 kexts and none of them give me sound, finally decided to use voodoohda and it works but sound is little distorted and there is a hissing noise, goes off when I mute the speakers. Also my sleep isnt working, it goes into sleep loop, sleeps for 1 sec->wakes up->sleeps for 1 sec and this goes on. Bluetooth seems to be not working, says module isnt present
Anyway keep up the great work guys! Finally I have a WORKING DUAL boot L502x
Thanks DoiX and AKennedy_4 WONDERFUL WORK!! :)
p.s where do I buy you a beer? :P

Underage my friend :)

But that works because that's where windows 7 stores the boot loader. If you have maxed out the number of primary partitions (4 with MBR partition table) the win installer will install the boot loader to the win 7 partition itself. Not to a separate system partition.
But anyways, cheers to finding a solution

Also sleep wont work on a07 bios. Only on a06

And make sure you have speedstep installed or sleep won't work without the sleep enabler kext

Also, the audio kext should work. Make sure your updated to the latest chimera (Don't know why but this did effect me at some point), and make sure you select internal speakers in the sound in systems preferences.

Hi everyone,

I have an issue. When I install the iAtkos system like it is said in the (updated) tutorial with the kexts (first Dioxs then from the package) the OSX stucks at the booting point where you can see the Apple Booting Logo. Once again: I choose iAtkos1 in the Bootloader (it's the only one because I haven't installed Windows) and the system begins to boot correctly. After a while the booting circle icon stops moving and the whole picture stucks. The funny thing is that when I press some buttons I hear that the system has booted because I get sounds even when I press the volume buttons. But all I see is the stucked booting screen. I can even shut the system down by pressing the power button and return after that.

What can it be? Something with the graphic driver?

I have the a07 Bios and my specs are:

XPS 502x : 2nd generation Intel Core i7-2670QM processor 2.20 GHz with Turbo Boost up to 3.10 GHz 1 SR
N11X5M06 1 SR
Display : 15.6" HD WLED True-Life (1366x768) with 2.0 Mega Pixel Integrated Camera 1 SR
LCD Back Cover : Metalloid Aluminum (WLAN) L501X 1 SR
Resource DVD : XPS L502x Diagnostics and Drivers 1 SR
Ship Accessory : German Docs 1 SR
RAM : 8.192MB (2x4.096) 1.333MHz DDR3 Dual Channel 1 SR
HDD : 750GB Serial ATA (7.200 1/min) 1 SR
Optical Drive : 8x DVD+/-RW Optical Drive 1 SR
Battery : 9 cell 90Wh LI-ION 1 SR
Graphics : 2GB NVIDIA GeForce GT 540M Graphics card 1 SR
Wireless : European Intel Centrino Wireless-N 1000 1 SR
Keyboard : Internal US/International Qwerty Keyboard 1 SR

Does someone know what it is?

Owen, try booting with the RbootLE and reinstall the kext from the pack.. and make sure your selecting the right DSDT (You would choose the HD DSDT not the Full HD DSDT

I had this issue too but memory is failing me to what the actual problem is.

If reinstalling the kext doesn't work (Remember kext utility and disk utility), then try posting on the other topic, Im sure DoiX or someone else can help you out

Hi guys,

I've installed Lion on my Dell and worked with it for a while. I don't think that I will keep it because the bugs are to big... The graphic card is not recognized, sometimes the system stucks for a while, here and there is a small bug.
I was thinking to use it really instead of a mac and work with programs like photoshop, logic (audio recording), final cut (video montage) but it all works slow.
Final cut 7 doesn't install at all, without reasons. Photoshop 6 is too slow.

Is it on me or is the system just full of bugs and not fixed yet?
Is it not better to install Lion through VMware on Linux???

Thnx!

here is your solution for missing BOOTMGR....


Put in Win7 disk, boot into recovery console
Type DISKPART (enter).
Type LIST DISK (enter).
Choose the disk that contains your WinRE partition. If it is disk zero, you type SELECT DISK 0.
Type LIST PARTITION.
Now select your Windows disk – the one you want to boot from. If it is partition 2, you’ll type SELECT PARTITION 2.
Again examine details with DETAIL PARTITION.
Once you’re sure, mark it active with the command ACTIVE.
Type EXIT to get out of Diskpart. You’re back at the commandline.
You need to be sure there are system files on the new bootloader drive. if that drive is C:, you will put them there with this command: BCDBOOT c:\windows /s C: (you can use BCDBOOT /? to learn the other options available.)
Now reboot the machine.

So the stock wifi card doesn't work. Will a BCM94321mc work? I have one sitting at home. Just wondering because I just ordered my my xps15 today and wanted to save time incase it didn't work so I would have to order the wifi card mentioned.
Sorry if my grammar was bad in that last sentence. It's late, and I got really excited after i ordered the laptop, since the one im using now is {censored}.

My System:
CPU: i7-2670QM
GPU: Nvidia GT 540M de 2GB
RAM: 8GB
Monitor: 1366x768

The first thing is to apologize for my bad English and my lack of knowledge of MAC, is the first time I use it.

I am following step by step guide and I have a small doubts that makes lion do not work properly at the end of the process.

1. Before the first reboot (step 8a), if I copy the DSDT drivers (my case) or Full HD video DSDT it does not work. As reboot works properly without copying them I've chosen not to place them. Is there a problem with that?
2. What Doix drivers of the package have I to install, just the three indicated?
3. If you install your package, what version have I to use 5 or 6? In any case, have I to install all the drivers that are in the package?
4. In there (Doix package), are two drivers 8,2. Do you install both?
5. In step 14) it sais "It Should Reboot OS X. Now with the boot normally any CD or arguments." That does it mean mac should reboot itselfs or you still have to boot with the rbootle.
6. In step 16), when you say Run Disk Utility, do you run it to repair permissions egain?
7. When is it assumed that the computer should restart by itself? at the end of the process or after step 14?
8. When I repair the permissions on the screen there are a lot of messages of files repaired, is this ok?
9. When I finish the process and reboot without the rbootle I get the screenshot attached.

Thanks in advance and thank you for the work that you have done.

The DSDT is needed for proper recognition of your hardware. Use Doix's package installer (V6 not V5) for the latest DSDT. and make sure you install the right Boot.plist option at the very bottom of the Package installer.

The system should work without RBootLE in step 14

I'm not sure what the difference between the two system definition's are. They seem to be the same. Either one will be fine

When you repair permissions; it is normal for a ton of permissions to be repaired

You misinstalled something. Try booting with RBootLE and reinstalling the kext from the Package installer, run kext utility and then disk utility. Reboot without RBootLe. If the system gives you a kernel panic again (That's what your screenshot is), try installing the kext from my zip file (Not DoiX package). Install them with Kext wizard to System/Library/Extensions after they install run kext utility and then disk utility.

After the install, i put the DSDT in the extras folder (HD screen not full HD) through macdrive in windows.
The screen is really weird looking with a whole bunch of random lines, but there's sound so I know I'm in the setup part.
However, i can boot into safe mode fine and the screen is okay, but i have all the kexts and the packages in a usb, and whenever i plug in the usb, I get a kernel panic immediately.
What could i have done wrong in the process?

Specs:
720p screen
8gb ram
2gb gt540 graphics
i7-2670QM @ 2.20GHz (yes for the busratio flag i did busratio=22 not 20)
A06 bios

Yea so basically my only problems so far is the kernel panic with the usb plugged in, and the native screen not working. It's the whole screen that looks messed up

Thanks for any input!

@jnxjn: I have the same problems as you.

The one about de usb can be solve pluging the usb just after you boot with Bootle (while you see the screen full of letters). After MACos is loaded you can use the USB.

About the problem with the DSDT some one called Alex DeWolf had the same problem and it was solved by DoiX this way:

11 January 2012 - 09:36 PM

Posted ImageDoiX, on 11 January 2012 - 02:48 AM, said:



Well, the only thing i can think of is that you are using the FULL HD DSDT instead of the normal one... http://dl.dropbox.co...DSDT-HD.aml.zip copy it to extra and add to org.chameleon.boot.plist

<key>DSDT</key>
<string>/Extra/DSDT.aml</string>


I have not still try it in my laptop, but if make it work let me know.

Bye.

calreyru1978 is right to an extent. Make sure your using the right DSDT and its put in the extra folder. This will solve the USB drive problem and screen all in one. Now to make sure you have the DSDT loaded, boot with RBootLE and enter these boot flags (Change the bus ratio value to your own as specified in the guide):

-v GraphicsEnabler=No cpus=1 busratio=20 DSDT=/Extra/DSDT.aml

You should boot with native resolution now

What calreyru1978 mentioned above is easier to be done through the installation of DoiX's package, but has the same results if you choose that route

I managed to boot with the DSDT=/Extra/DSDT.aml flag. Now my problem is booting up without the cd. I used DoiX's package and installed what the guide said to install, edited and replaced the boot.plist as the guide says, deleted the nullcpu kext and I'm still not able to boot without the cd. Anyway, I then boot with the cd, and manage to install ##### and all of the options it tells me to select. The bootloader is v1.7 from the new #####. Now, i reboot and get a kernel panic. The "please hold power button to restart" screen is blocking some words, but i managed to catch a few letters consisting of achi (not in that order) and an audio family thing too.
Any suggestions what might be wrong?
Btw I'm still on 10.7.1 so I didn't do the part where it says to change to the 10.7.2 AICPUPM, and didn't install the combo update.

While in osx though, I faced a minor problem. The sound works but there is some weird white noise coming from the speakers.
Also while booting up, there is a popping noise too then after that the speakers start to make the white noise.
Any way to fix that or do I have to live with it?

Thanks again!

Hello egain.

I think we (jnxjn) and me have the same problems. I have reinstall osx and folow 100% the guide (using the HD DSDT (the one I need) suggested in the topic). The result has been the same blank screen (see the screen shot).

Attached File  IMG_20120207_184254.jpg   571.77KB   22 downloads

I have also installed the FULL HD DSDT, just in case, and i was not able to rebootLE my osx.

I have reinstalled once more osx and try the DSDT from here http://dl.dropbox.co...DSDT-HD.aml.zip, and I have been able to restart osx, but not to reboot without bootLE.

I'm almost sure that the problem is the DSDT.

I don't know else can I do....

You need to edit your SMBIOS.plist and set your identifiers as MacBookPro8,2

This solved the issue for me.

Use Macdrive in windows to edit this plist, or even boot into single user mode (-s)

@Owen, with you it may be "GraphicsEnabler=no" flag is not being set, If you do not do this the system tries outputting through the Nvidia chip, which is not supported.

You get the initial gray apple boot logo and sod all after if you don't specify that.

I managed to boot with the DSDT=/Extra/DSDT.aml flag. Now my problem is booting up without the cd. I used DoiX's package and installed what the guide said to install, edited and replaced the boot.plist as the guide says, deleted the nullcpu kext and I'm still not able to boot without the cd.

You've installed VoodooHDA, get rid of it.

There is a collection of Dell ALC665 Kexts knocking around, I'll post them if i can find them.

The issue you will be getting is due to a conflict with AppleHDA and VoodooHDA, remove one or the other.
If sticking with Voodoo, you need to go to the VoodooHDA.kext/Contents/Info.plist and find the "igain" value, set this to 0, save the changes, fix permissions and reboot.
