Lion 1.7.2 on Acer Aspire Timeline U M3-581tg

Recommended Posts

Hi Everybody!!

 

After messing around with many linux Distros, i've recently been attracted from the OS X, and wanted to get it working on my notebook. After many tries, following lot of different guides (non3 of them completely working to say the truth), I finally managed to install Lion 1.7.2 on my fresh Acer M3.

 

The point of this Thread is help someone elsa with my hardware to accomplish this goal and, hopefully, get some help to make things works better (well, in some cases, just make them work would be enaugh :wink2:)

 

see signature for complete hardware specs, anyway these are the main characteristics:

 

Acer Mother board model MA50_HX (Bios: Insyde corp v1.08)

Core i3-2377M

Built-in HD3000 + nVidia Optimus discreete card nVidia GT640M

Atheros AR9462 + NetLink BCM57780 Gigabit Ethernet PCIe

Standard PS\2 built-in Keyboard + Elan PS\2 Port Smart Pad

 

I've to say that I'm quite good at linux, but completely new to OSX so I'm just starting to understand Kext, smbios and so on...

 

What i've used:

 

8gb USB stick

iAtkos L2 dmg

Chimera BootLoader (without this, touchpad isn't recognized during installation)

 

Now that's what I've done:

 

Downloaded iAtkos L2 dmg

 

Installed it on VMWare (just to have a functional OSX for partitioning, restoring images etc), followed that guide that works really stright forward http://ilpico.it/wordpress/?p=2642 (It's in Italian, anyway if someone needs it I can traduce it)

 

From Lion VMWare (or another working Mac OS), mounted the 8gb usb stick

 

Entered Disk Utility, select the USB Stick, in "Partition" tab, selected 2 partition from the dropdown menu (i've used GUID partition table)

 

Selected the first partition and changed size to something like 300-500MB, named it "boot"

 

Selected the second partition and named it "iatkos"

 

Partitioned the usb stick with this partition scheme.

 

mounted iAtkosL2.dmg image

 

in disk utility clicked on the mounted iatkosL2 image, and the in the expanded image

 

Selected restore tab, dragged the expanded iatkosL2 image from the left inside the "source" field, dragged the "iatkos" partition inside the destination field. Proceeded to restore

 

During the restore process, downloaded latest chimera bootloader pkg (i've used Version 1.9.2)

 

When Restore process was complete (about 15-25min), opened the chimera pkg and then doble clicked the installer

 

Proceeded througt the installation and changed the install destination to "boot" partition on my USB Stick

 

When installation finishes, unmount partitions and rebooted

 

At start up, selected the usb stick from boot menu

 

In chimera boot loader, booted the iatkos image with -v GraphicsEnabler=No (otherwise the system tries to use the nVidia Card and cannot boot)

 

Using chimera, when install screen arrives, touch pad was working, so proceeded trought the installation, initialized the partition i've wanted to use (i've used the whole 20GB SSD), selected only PS/2 Kext for making also the kayboard working. Also selected both Atheros driver but didnt' make my wifi card work.

 

After install, booted in arch linux to remove every AppleIntelHD* and AppleIntelSNB* kext, otherwise boot hangs, even with GraphicsEnabler=No

 

rebooted installation processes only for fixing permission trought disk utility

 

Powered off and booted from SSD with GraphicsEnabler=No, this time i was able to reach the mail screen!!

 

entered sytem setting -> chimera bootloader (or maybe it's called chameleon inside the system setting menu', dont remember right now), changed resolution to 1366x768x32, checked the "GraphicsEnabler=No" as boot option

 

That's all, right now didnt apply any extra kext or smbios or dsdt.

 

Now, that's wht's not workig, hoping some one can give me some good tips!

 

- NETWORK: nor Atheros AR9462 nor NetLink BCM57780 Gigabit Ethernet PCIe get detected. Simply no network interface. (En0 not present). Any suggestion here?? I think for the atheros there isnt much we can do, but i think should be possibile to make the ethernet work!

 

- GRAPHICS: Intel HD3000 is recognized as "built in graphics", with only 64MB of memory and no specific Kext used for it. How can I use the intel HD3000 kext and graphicsenabler=yes without having the system tryng to use the nVidia card??? Maybe romoving nVidia Kext and placing back intel HD and Intel SNB???

 

- INPUT: Keyboard it's ok, touch pad works with basic function (no gesture at all). anyway if I go in system settings -> touchpad, there's no device listed

 

Anyone can suggest some fix for those problems? Should I fix my dsdt (if yes.... HOW??), should I use a smbios different from the stok one inside iAtkos (MacPro3,1)???

 

Hope this post will be usefull to anyone with this hardware configuration, and hope some good soul will help me fix these issues!

 

Thank you in advance!

    • I guess having pre{max-height: 500px;overflow: auto;} in CSS was too much for IPS Devs' tast.  Until an admin has hands on this, you still can use stylish plugin to accomplish it.     In fact, it is pretty easy than it appears - Just apply a simple click on the codebox (it will highlight it), then 'delete' key.
    • all the possible frequencyes i have added seems to work fine at the moment, i have added a lot of different frequencyes to support better all kinds of professional applications, inclunding strange sampling rates and goes from 8khz up to 176.4 khz, unfortunately 192 khz does not seems to work even on cards which should support it like the audigy rx, but other frequencyes just works fine and at the moment i have tested only the sound blaster audigy rx and the audigy sb0090 (1st gen audigy) and i can confirm that all the frequencyes from 8khz up to 176.4 khz does work on that card, so i think that such frequencyes should work on all the audigy 2, 2sz, 4 cards as well, tomorrow i will test with my sound blaster live! cards and i will let you know, but here are also some photos (pro tip: use cmd + alt/opton + 4 and then press space to make a screenshot of a single window):
    • Guy's if something happened, this is most likely Admins and Moderators are working there, yes we still need some things to be done, but if it's still not yet, it's because of time or something we don't know, we just have to be patient! Slow things is just because they are working in the same time, patience for that problem is good, and loading things, but apparently now is good, for me these things I've accounted them yesterday and this morning, but now they are gone. For the missing things like the Old insanelymac and theme, please we need them, and excuse my ignorance!
    • Good evening to all. So, I have an external 1TB seagate HD and it always reads normally, but now when I plug it into my HACK it just does not read, it does not even appear on the disk utility. The light always turns blue from the HD without blinking. However I plugged it into windows, on a macbook and it worked normally. I already formatted my hack but it did not work. Thank you in advance for the help and sorry my bad english   my kexts: AppleALC.kext FakeSMC.kext IntelGraphicsFixup.kext IntelMausiEthernet.kext Lilu.kext WhateverGreen.kext VoodooHDA.kext USBInjectAll.kext NvidiaGraphicsFixup.kext   GTX 1080 Windforce core i5 7º generation 8gb Ram H170M Plus BR
