Re: HP Pavilion dm4-2070us 10.7.2 (2 cores 4 threads) [PROGRESS]

SUCCESS!!!

I finally got it working!!! Clroxas you deserve a case of beers! Thank you so much!

No problem! I'm glad we have another DM4 owner with a working 10.7.3. You do have full resolution and smooth accelerated video right? Don't mind the reported video memory, Intel HD3000 does not have dedicated video memory, it doesn't affect anything. I can play videos smoothly in full 1080P HD through the HDMI.

I live in Vegas, beer is free. In fact, I just got back from the casino to celebrate Easter, I get the buffet for free too. Cheers!!!!

Yes! Everything runs buttery smooth and beautiful! It took me a week but I finally got it thanks to your help! It was such a daunting process but it was all worth it!

Now to look for compatible mini wifi cards with widi!

clroxas,

I've run into a little snag. Netflix seems to not work with any audio in safari or chrome. The video plays fine but there is no audio. Audio works fine on the laptop otherwise its just on netflix I dont get any sound. Do you know why this is or know of a fix for it? Do you get sound on netflix on your dm4?

Opensourcefool shared his find in getting sound, but it makes my system randomly KP. Try it.

I used the kext found at http://www.osx86.net/downloads.php?do=file&id=2291 and followed the directions as far as which kexts needed to be removed from /S/L/E, but I put the new kexts in /Extra to keep things a little cleaner.

I've tried his method. It works very well and I do get random kp's as well. The only thing is whenever I play any video on youtube or in the browser, the audio works fine. However, when I switch the video to HD or if I try to watch netflix the sound doesn't play anymore. Any idea as to how to fix this?

I get sound in Netflix using Firefox. I read somewhere that the new Silverlight is not compatible with Chrome or Safari. The sound volume can increase further if you go to the VoodooHDA prefane and click on Enhance stereo while on the 1:Speaker (Analog), and slide the Stereo base all the way to the right.

The sound in Firefox Netflix is random. Right now that while typing this reply, "Meet The Parents" is playing with sound. It started without sound, then it just popped out after a few minutes.

I updated to 10.7.4 using the combo package downloaded from Apple. I am only able to boot with cpus=1 flag even with the patched mach_kernel.

With the cpus=1 flag, the Geekbench score went down to 3410. Cinebench OpenGL= 11.31fps and CPU=.82. Cinebench detects 0 cores and 0 threads (10.7.3 it's 2 cores 4 threads).

I am waiting for a 10.7.4 patched mach_kernel for the HP.

Hi!

I'm new here in the forum. I currently own an HP DM4T.

I do not want Lion. I am good with Snow Leopard. Which instructions should I follow?

Thank you.

Thank you.

locomotion, I googled your laptop and it looks identical to the dm4. I am confident that the guide I have in here on page 7 http://tonymacx86.com/viewtopic.php?f=170&t=34709&start=60 should work with your laptop with all the caveats of course. Substitute the Lion for Snow Leopard. The issue that I am anticipating with Snow Leopard is the graphics. The built-in HD3000 might not be fully supported in Snow Leopard.
___________________________________________________________________________

Prepare your Laptop by choosing your method:
1) Remove the stock HD and put a blank hard drive (Disassemble HP Pavillion DM4).
or
2) Attach a USB external hard drive .

• Create a USB install following tonymacx86
• Run Multi-Beast as instructed above and choose only EasyBeast Install, MacBookPro 8,1
• Delete AppleHDA.kext and AppleACPIPlatform.kext in S/L/E
• Edit contents of AppleGraphicsControl.kext in S/L/E. Show package contents then Contents/Plugins, remove ApplePolicyControl.kext (chentianwen.net).
• Download Taptun's modified mach_kernel: 10.7 Taptun Lion Kernel and show all files (Show All Files) then replace (backup first) the original mach_kernel with taptun's modified mach_kernel.
• Edit your org.chameleon.Boot.plist and change the following: EthernetBuiltIn=Yes, Kernel=mach_kernel, Timeout=2, GraphicsEnabler=No and UseKernelCahe=No. I use Property List Editor
• Reboot using cpus=1 (only for the first boot)

If you have Extra/Extensions, check that you have only these kexts (delete any extra kexts and run the kext wizard maintenance.
AppleACPIPS2Nub.kext
ApplePS2Controller.kext
AtherosL1cEthernet.kext (file attached below)
FakeSMC.kext
NullCPUPowerManagment.kext

If you don't have Extra/Extensions copy the attached Extra folder below. MultiBeast creates these kexts in S/L/E, delete them then repair permissions and rebuilt mkext using kext wizard.

Post Install:
• Combo update 10.7.3 by downloading and installing 10.7.3 Combo Update
• Delete AppleHDA.kext in S/L/E
• Edit contents of AppleGraphicsControl.kext in S/L/E. Show package contents then Contents/Plugins, remove ApplePolicyControl.kext.

If you want sound, opensourcefool shared his find to get sound. I do get random KP’s with the sound in my Laptop with this fix.

I know that this thread has been slowing down, but it's the only place I see anyone making progress with the dm4-2070us. I wanted to offer some hope for IDT audio with the 64-bit kernel -- because it's working for me right now!

I'm running 10.7.3, installed clean using Unibeast+Retail 10.7.3 from the App Store, vanilla kernel, no DSDT.

[EDIT]I've received a few PM's asking what flags are necessary to boot from the Unibeast installer. I just use cpus=1, which seems to be necessary no matter what for now.[/EDIT]

I used the kext found at http://www.osx86.net/downloads.php?do=file&id=2291 and followed the directions as far as which kexts needed to be removed from /S/L/E, but I put the new kexts in /Extra to keep things a little cleaner.

Further good news is that with 10.7.3+Unibeast, all USB ports work at full speed without any kernel panics, which was a big issue even with a carefully tweaked DSDT in 10.7.2.

Has anyone else been making headway with this model? It's such a gorgeous little notebook, it's a shame that it has provided us with so many headaches

I have the DM4-2191US Version, got most of it working, except for the wifi. I did performed the Geekbench test before and after installing the Taptun Lion Kernel, before was 3095, after is 4918 and it is showing 1 Processor, 2 cores, 4 threads. Did not have to use cpu=1 anymore had 10.7.1 and updated to 10.7.3 will stay on that one for a while. I did try 10.7.4 but the USB ports/Camera keep messing up.

Next step: Dual booting/install Windows 7(I hate Windows 8)

I'm glad you have your laptop up and running. I have not tried 10.7.4.

If you are choosing to dual boot using your existing HP hard drive, take extra care and make sure that you clone your drive. I've messed up the MBR several times and had to copy back from my backup before I got it right.
