Acer Aspire One A150: Install Snow leopard on MBR partition

[jerrycrystal]

I posted it on the AAO forum originally. To let more people see this, I repost it here.

 

This guide is LARGELY based on "simpler installation guide Snow Leopard retail dvd WORKS!!!!", thanks to "erikazra"

 

The advantage of MBR installation is dual booting SL with other OS easily. ----- I get dual boot by doing nothing (before installation, Win7 is already installed on my machine)

 

I uploaded all necessary files to http://www.mediafire.com/?sharekey=918589d...edb9ae41c2803ed

 

1. Obtain SL DVD dmg.

2. Make this dmg writable, and replace "OSinstall.mpkg" with the modified one, to make it installable on MBR based partition scheme.

3. Restore this dmg to a partition, install SL (run "OSinstall.mpkg") on a MBR partition, we say it SLOSX.

4. Install Chamelon2 RC3 V658. (We can manually install boot0, boot1h and boot to make sure)

5. Put "fakesmc.kext" and "disabler.kext" to SLOSX, delete "AppleIntelCPUPowerManagement" (deleting this seems important to be able to boot SLOSX again).

 

Install below kexts using kext helper

 

6. Install "AppleACPIPS2Nub.kext" (This kext is not necessary --- thanks to SP1950, but I haven't tried to delete it) and "VoodooPS2.kext"

7. ! don't install the "RealtekR1000.kext", the boot process will not stop. ---- maybe someone can provide a useable one! Thanks!

8. Install "AppleACPIBatteryManager.kext"

9. Install "VoodooHDA.kext" (it is the one in http://code.google.com/p/voodoohda/downloads/list, version is currently 0.2.1 beta)

 

There maybe problem in repairing permissions, that's fine, I quote others' words:"From what I've read on the Apple support forums, that error is normal in Leopard and SL and doesn't really mean anything is wrong. The advice was to just ignore it."

 

10. (updated!!!) Graphics: use "AppleIntelGMA950.kext" and "AppleIntelIntegratedFramebuffer.kext" from pkg "my_graphic_drivers". DO NOT DELETE ORIGINAL "AppleIntelGMA950*.bundle"

 

The "AppleIntelGMA950.kext" is from "asrikaran", BUT the "AppleIntelIntegratedFramebuffer.kext" is from my 10.5.6 ideneb installation. I confirmed that I can enable QE/CI only in this way. I don't know why.

 

I think the most important thing is the com.apple.Boot.plist, the content is

 

<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE plist PUBLIC "-//Apple Computer//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">

<plist version="1.0">

<dict>

<key>Kernel</key>

<string>mach_kernel</string>

<key>Kernel Flags</key>

<string></string>

<key>boot Graphics</key>

<string>yes</string>

<key>Graphics Mode</key>

<string>1024x600x32</string>

</dict>

</plist>

 

I suggest to install kexts one by one, and reboot each time, wait minutes if the system SEEMS frozen.

 

11. use "voodoopower.kext" to enable speedstep.

 

Update: 10.6.1 upgrade is OK. Simply backup the "AppleIntelGMA950.kext" and "AppleIntelIntegratedFramebuffer.kext", run upgrade, reboot, re-install the backuped kext, then everything is back.

 

--------------------

*broadcom 4311 working

*QE/CI working (you can check this by setting the menubar transparent, or adding a widget to dashboard)

 

*realtek network card not working

*sleep not working

*card reader not working (update: using IOSDHCBlockDevice.kext, it can work)

Hey... Glad I caught you maybe you are still online.

 

My Acer Aspire One A150 is stuck at Still Waiting for root device. I used a retail DVD from the Apple Store. I made a iso of it and installed it form my leopard partiton.

 

Hmm. I've tried what I know to be everything.

 

Any help is appreciated.

 

Thanks!

Well. it is always said that "waiting for root device" is caused by the sata settings. I have never encountered such a problem.... really sorry.

Glad you are still on. Maybe we could insanelymac chat. Anyhow I'm going to erase my partiton, and follow your guide. 1 question. For kexts you said to install using kext helper do you mean after I boot into 10.6? I'll be on irc.macspeak.net Channel InsanelyMac

Hi, jerrycrystal. Since I'm a Chinese, I don't have the access to the "mediafire.com", so I can't download those files you've shared that are really necessary for me.

 

So, could you please send the file named "IOSDHCBlockDevice.kext" to my E-mail(lz0812@gmail.com)?

 

Many thanks!

Hey, were you able to get the ethernet or the wifi working? I've been trying different methods for the wifi, but with little to no luck. I haven't really gotten around to tackling the ethernet yet.

Thanks.

 

I've been thinking that the 10.6.2 airport update might help, but I need some way of accessing the internet in order to get it to update.
