Hi there,

well as far as I know, there is not a modded BIOS for our little Notebook...
The latest BIOS on the Acer site is the new UEFI BIOS, that is not compatible with my machine. So I am using the good old EFI BIOS 1.12.
As long as your machine wasn't delivered with the UEFI Bios, it just won't work. Flashing this BIOS will definitly crash the computer and will left you without a chance of flashing back the BIOS.

So: I tried booting with the nvidia GT650M on, but it leaves me with a black screen. I guess a EFI-string in the chameleon plist could make a change, but really I was too lazy to try so far.

For me the Bluetooth working (with switching on/off) is great and I am still searching forums for a solution to the Atheros WLAN. Damn, I read that I should have worked with LION or SL... The Cardreader is my second thingy to look for and at last (the most important thing for me) get the USB3.0 ports working. Hell, I just don't know why they just do not work.

So... I still working on it.

Hi there,

now, I have got some news.

Well, for the GT650M... I managed to get it recognized correktly by the System by using a device String in the boot.plist from chameleon. It doesn't work though, but I think at the moment the only thing we can do is disable the Optimus feature in the dsdt for the Nvidia to work. I do not want to do this, but maybe I will try.

For the USB 3.0: I installed a Extension today from OSX86 Downloads called "GenericUSBXHCI 1.1.4" and guess what. After a Restart the two ports are working fine (Tested with USB 3.0 Stick and USB 3.0 HDD). Yeah!

Hope this helps.

and sorry for my bad English, but I'm german ,-)

hi

not right now.. I am still reading the posts on how to disable Optimus in DSDT to enable the nvidia and back. Some guys made it by making 2 DSDT.aml which are switched by a script to enable either the Intel HD4000 or the Nvidia. The Intel seems to consume less battery power, which is not that important for me, because I usually don't run around with the notebook.

I'll post again, if either the nvidia or the PCI card reader is working... (and of cause the Atheros WLAN).

Oh, for your WLAN 9285: Did you use the earlier mentioned OIatk3frmwr.kext? - This thing loads the Atheros 3xxx Firmware for the Bluetooth module and works with the installed card. It should work with yours too, so you will have bluetooth...

Ups, i forgot: my device string from chameleon.boot.plist for the Intel AND the Nvidia combined, so they are displayed right in System Information:

<key>device-properties</key>
<string>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</string>

I know it is long, but work here on my machine with a mbp9,1 or mbp10,1 smbios. If you want I can also post the "normal" plist files, if you want to edit these.

I just managed to install Mountain Lion using the Pandora's Box which you can find in the Downloads section. You need to use the elan kext for the touchpad to work, and the ps2 kexts mentioned in this thread for the keyboard to work during installation.

After the installation went fine, I had my first kernel panic with the AppleIntelCPUPowerManagement, to correct it, I booted from the installation USB stick again, and patched the file using the following command

sudo perl -pi -e 's|\xE2\x00\x00\x00\x0F\x30|\xE2\x00\x00\x00\x90\x90|g /Volumes/OSX/System/Library/Extensions/AppleIntelCPUPowerManagement.kext/Contents/MacOS/AppleIntelCPUPowerManagement

Replace OSX with the name of the partition on which your OSX will be installed

try it and see if you can boot. Remember to boot everytime with the -v option when selection your boot partition, and post any errors you may encounter or if something gets stuck


Hope this post was helpful

Hello,

I installed Mountain Lion on my Acer v3-771g and HD4000 works,but the display is not at full brightness level and I can not increment the brightness.Does anybody know how to make it brighter?

Shortcut keys do not work.

And I would like to ask if anyone experiences some issues with the touchpad on this laptop cause mine sometimes works,sometimes it does not.Sometimes when I put my finger on it,the cursor slides to the left side of the screen and I am not able to use it.I have alps touchpad unfortunately :( .

Thanks

Hey guys, I hope this is good news for us owners of an Acer V3-771g

After some research I just found this modded bios for the V3-771g, unfortunately it is not universal, as it works only with the laptops that came with Windows 7 Preinstalled

It also updates the preinstalled BIOS version to 1.12 (mine came with 1.07).

It is a zip file that can be used to flash using either DOS or Windows, I chose the Windows updater (InsydeFlash.exe). It should have the same ID on the Current BIOS and New BIOS Fields.

I have to admit that I felt reluctant to try to update my BIOS but after looking at some success stories, I decided to try it myself and voila! it works and it adds and advanced tab where we can en/disable the integrated graphics to finally get the GT-650m to work on Mountain Lion.. yay!

It has a lot more options, but sincerely I was too excited to look at all the options at that time.

For all of you willing to try every option in the BIOS this is the link

https://dl.dropboxus...1G_Unlocked.zip

And remember, it should NOT be used with V3-771g's that came with Windows 8 Preinstalled. Trying to use this modded BIOS on such laptops might likely brick the laptop with no chance of booting it, so be wise on this step.

Happy Hacking and I hope this will finally enable our GT-650m to work.

Hi there,

haven't looked around for a while...

I'm using brightness slider from the app store (freeware) to control my brightness. Yes, the key.combinations on the keyboard are not working. I just patched the DSDT with PNLF patch. It installs the functionality to get the brightness working. Well I am now having the brightness level to full on login, but who cares :-) A better solution is the Shades.app (Freeware control panel and/or Menuitem).

I've got the ALPS Touchpad too and I use it every day. I took a few weeks of looking, but I found out that the VoodooPS2 version included in some DELL forum here (for ALPS) works very well, including swiping and two-finger-gestures. It even works with the bluetooth mouse OR a PS/2 USB mouse.

Me too. The Chameleon boot loader does not interfer with the win8 partition at this level (Shutdown/sleep)... As I have the same configuration: this might be more a win problem. Except you installed OSX to the same SSD as Windows. But thus you won't be able to boot as far as I know ;-)

I have Windows 8 and Mountain Lion on v3-771g and after installing Acpi kext in ML for some unknown reason Windows 8 does not shutdown and also doesn't ennter sleep mode.I have chameleon boot loader.I want to know if the bootloader affects Windows because ever since I installed ML Windows is behaving strage.

Hi,

so that sounds like my system (win7 pre installed) ... I'll try the file and enable the nvidia. Let's see what happens.

This only leaves my Problems with the Atheros 9462 WLAN card open (I think I tried every hack I know).

Good job.

Well yes I have Windows 8 and Mountain Lion on the same harddisk.Ever since I installed Mountain Lion,Windows 8 is acting a little strange,as I mentioned before the shut down and sleep issues,but I also receive a message in the action center stating the fact that there are errors on the disk and a scan is needed.I think it is related to the chameleon bootloader and the "Turn on fast startup" feature in the power settings.When I had Windows 7 there seemed to be no issues.I`ll try to look into that later.

Regarding the Bios Mod,I flashed my old laptop with an unlocked version to enable VT-x and I succeeded.Here is the thing,just to let everyone know that every laptop has a backup method to recover the bios in case it is wrong flashed or it does not work.This information will not be available in the user manuals which get shipped with the laptops package.It is called the disassembly guide.So I looked for it and found that in case a bios is flashed incorrectly,the user is supposed to do this:-put the bios files on the sd card,put the card in the laptops slot and power on the laptop while holding some specific keys from the keyboard.Then I noticed the fans started to spin at max speed and after 5-6 minutes it turned itself off.Then I pressed the power button and it was back to factory settings.

I had Acer Aspire 5738zg and the information was provided in the assembly manual which one can find it online just by googleing it.

I got the bios mod from this site bios-mods.com .

The Wi-Fi on my V3-771g does not work,however I exchanged it with the Wi-Fi from 5738zg which works out of the box and its very good,it is Atheros AR5B93.

About the brightness issue I saw that the screen turned to full brightness after I installed a kext to enable sleep.So after I installed the kext,if I put the laptop to sleep after waking it up it goes to full brightness,but I have no fn keys.Shades is not ok,because it uses a transparent layer over the image,therefore it is not it.

I got the kext for the battery which works ok,however the battery only lasts for about 1 h and 45 min,whereas in Windows I think I can get more.I wonder if this is related to the CPU,how do I know if I got all the states working, C states and P states?

I wonder if I can get the VGA port to work,that will be great,I`m looking forward to it as I`m using 2 monitor most of the time.

I have a request for Wartomato can you upload your working ALPS kext please cause I looked for a working one and I couldn`t find it,also I would like your DSDT with the brightness feature please.

Hi

I have the same brightness problem, once the computer is waking up from sleep (even if sleep doesn't work properly) the full brightness finally shows up. It would be great if wartomato could helps us on this issue.

As for the Windows behaving strangely, I have to say that the same is happening to my Windows 7. When I am using Mountain Lion for about one hour to one hour and a half, some keys stop working, more specifically, number 9 (the one over I and O), O, P, L, ', and . (point). I was scared at first because I thought it was an imminent hardware failure, but some time after, the keys started working again, and then stopped working and so on. But the real problem is that, when I boot into Windows 7, the same problem shows up, and I was unable to log in to windows because my password contained one of the non-working keys. I had to use the on-screen keyboard feature, only to find out that, after some minutes the keys start working again, and then stop working, and so on (just like in Mountain Lion)

And even stranger, is that, the less I use Mountain Lion and I start using Windows exclusively, the problem is less and less frequent (although it does not go away completely). I think this might be related to either the chameleon bootloader, or the AppleIntelCPUPowerManagement unable to set correctly the P-states and C-states.

If any of you guys have been having this problem it would be great to share a solution, because I do a lot of coding and because of that, I need the keyboard working most of the time.

Also, I have the battery problem too, and I definitely think it is related to the AppleIntelCPUPowerManagement unable to set correctly the P-states and C-states, I patched that file using a perl command I posted a bit ago, and so far I Have only experienced two fan speeds (with the lower fan speed running a lot faster, and the computer heating a lot more than on an 'idle state'), and this leads me to think that my AppleIntelCPUPowerManagement is not correctly patched. If wartomato or someone else has a working AppleIntelCPUPowerManagement with the right number of P-states and C-states, it would be also great to share it with us who are still having trouble setting up the hackintosh.

This would be all for now, and I am also still searching for a solution to the wifi problem, I've read somewhere that since a combined wifi+bt combo does not exists in real macs, there is a low chance of ever getting this card to work, but let's hope that, the author is wrong and there is a final solution for the wifi.

Happy Hacking.

Well about windows acting strange,I can say that after disabling the "Turn On Fast Startup" feature in Windows 8, Shut Down and Restart works again.I read that Windows 8 keeps some files like it would do when hibernating.If I boot Mountain Lion with -v flag I get something like this "Windows is hibernated.Will not be able to remount.Run chdsk".What I don`t understand is if I got a separated partition for Mountain Lion,what in the world is OSX doing with the Windows partition?

Okay,... a lot of open questions and probs.
Well, I am not ML Wizard or something, but...

For the Brightness: Yes, your porblem with the FULL Brightness is a known prob in the community as far as I read it. This also happens on many other laptops. Yes, it has someting to do with the sleep mode and the restoring of the display state after that. For now I go along with the very bright display, because patching the dsdt didn't quite work out the way I want it. I could't get osx to recognize the display in the system prerefence... Anyway, with shades installed I found out, that it restores the brightness, but the brightness goes up to 100% depending on the Programm I use. I'll put it this way: Use a game that uses the graphics card up to full or fullscreen and the display will be at 100%.

For the "hibernation file" issue: Yes, I got it once myself. That doesn't have something to do with chameleon directly, because a bootloader can't boot a system correctly that is in hibernation after a shutdown.
This is partly due to the SSD, but when your notebooks "just" hibernates and does not really shut down, well you might run into problems. Thank you Bill Gates... Oh, yep, I disabled the "Fast Startup" feature as well, because I think, that booting an SSD is really fast enough. This feature is more for the newer 771G with the 2.1x UEFI BIOS and other Ultrabooks.

For the keys: What? - your keys don't work in ML after some time? - Strange. I never had these issues.

For the BIOS: I patched a day ago.. yep, it is working. I tried a few times until now to disable the hD4000, but without success. I will work on that... I ran into another thread that stated this as not possible, because the Acer NEEDS the Intel to boot and then switches. As for now, this seems to be right. I ended up with a black display for about 10 times (but loading BIOS defaults without a display made my day). Hmm, this guy in the thread might be telling the truth.
At least I find it interesting that the HD4000 compared to the GT650M is performing about two times better under win8 on my system (double fps using OpenGL tests over nvidia).
I tested this four times with the same result.
Strangely the HD4000 on ML performs two times faster than on win8 using in-game-fps-test (fps is two times higher). I am really thinking about leaving the nvidia behind at the moment, but we'll see.

For the powermamagement: Aha, on my machine the Battery doesn't really last longer on Win8 than on ML.
I know about the "could not generate p-states" thing in chameleon, but since last week I am using a different approach. I found a script (origanally by the decesaed revogirl) that helps out quite well:
http://www.tonymacx86.com/ssdt/86906-ssdt-generation-script-ivybridge-pm.html
Just follow the instructions, pass 3300 (for the Mhz of our CPU) and you get a SSDT-PR.aml generated. Rename to SSDT.aml, copy in Extra folder, disable Generate P-/C-States in boot.plist and activate "drop SSDT". Viola. check bdmesg for the results and the temperature of my CPU dropped.
The CPU Clock always only displays 1.19 or 2.3 Ghz and a multiplier of 12x or 23x in HWSensors by kozlek, but my battery lasts as long as on Win8. (Oh, yes you still need the patched AppleCPUPowermanagement).

Last thing: Well, I never tested out the VGA-Port, but my HDMI-Port is working ;-)

In the kexts section I see only the Elan Touchpad kext uploaded by iFire which does not work.Am I looking somewhere else?

Also did anyone solve the clock/time issue ? Windows is left behind 3-4 hours after boot,after using Mountain Lion

My laptop frezees a lot when I run YouTube or other apps which use the grafic card.Does anyone else experience this?


this is the device id which I use to make HD4000 work in Chameleon


<key>device-properties</key>
<string>7f0000000100000001000000730000000200000002010c00d041030a000000000101060000027fff04002c0000004100410050004c002c00690067002d0070006c006100740066006f0072006d002d006900640000000800000004006601140000006800640061002d0067006600780000000d0000006f6e626f6172642d31</string>

the kexts with multitouch for alps finally appeared in the Downloads sections,but it does not work for me.If I boot with -v flag it I get failed to load the kext and error and it doesn`t boot the system either.Also said something about duplicated class
