I experienced those two things to be reasons for Wake from Sleep not to work on some setups...

Ah yes. Your right. I remember having problems with sleep because of my UHCI. To fix it add
<key>UHCIreset</key>
<string>Yes</string>
into your com.apple.Boot.plist

Becomes in binary:
86 80 A2 27

Replace the device id closest to your card with your one...
Checked...
0x25828086 in Info.plist becomes
0x25928086
for both plists

for both binaries use 0xED to search and replace (in hex).
86 80 82 25
to
86 80 92 25

Binaries are allways present in Contents/MacOS (if you didn't know it).
Install both in S/L/E instead of original kexts.

Follow other steps in tutorial and if the bootloader install fails install Chameleon 2 RC4 stock and replace boot with the attached one...
Hope this helps you out...

Hi experts.
I'm a total newbie in OSX86, but I managed to get a Hazard OSX 10.6.2 up and running on my Lenevo R60 laptop.
The only thing that's missing is the GMA945 videocard.
The pkg-installer faild, so I tried to replace the boot-file in /.. and install the two kext's downloadable in the first post. I included "Graphicsenabler" in the com.apple.boot.plist. No luck. So I have given up. The screen works, but only in 1024x768 resolution. And therefore the DVD-player will not work.

Now I have the pre-boot verbose PCI UUid list with "press any key to continue" before the chameleon logo-screen.
How do I get rid of this verbose (and "press any key to continue") during bootup ?
I have no "-v" in com.apple.boot.plist.
I think this PCI-list shows up before com.apple.boot.plist is read. Is this correct ?
I did not make a backup of my old boot-file in /.., so I can't get back to my old way of boot.

Hope you can help.
I'm sorry for my "newbie-question", but I'm ready to learn !

Regards
Stha

note 1: its GraphicsEnabler=Yes under kernel boot args
note 2: get boot rel3 (from insanelymac, same topic)

Wow. Thanks for this - finally found a way of getting some support for my Vaio W in 10.6.2. I'd tried a few fixes and this one gave me the most success.

One big issues - when I follow all the steps except updating the bootloader the only output I can get is via VGA, the netbooks LCD goes black - but when I install the new bootloader (from first post and the one a few posts later) it causes the computer to sleep after the gfx initialises - and from what I can tell still only works to VGA too.
Any pointers?

Edit: Just rebooted, NO KERNEL PANIC FOR FIRST TIME AFTER REBOOTING YUHOO ( sorry, i got excited for not seeing stuck at boot thingy).

but no resolution improvement, idont have com.boot.plist thingy, i tried to install chameleon R69 version i got from some rapidsharefile you posted in chameleon mailing list, it failed to install sadly

. how to go about this now?

EDIT After 24 hours:-
So this time after reinstall, I came across NetbookInstaller , It took some 20 mins to finish its job on a plain iAtkos S3 installation on my MSI U100 netbook, asked me password more than 2-3 times, after it finished, i rebooted and viola , i got hi-res desktop, but its just weird res. check attached images.

Andy, how to go about installing your files now? should i also replace boot file that you have attached in later replies? waiting for your kind reply.

VideoHardware info, its GMA 950 27AE and About This mac Gfx info with files on /

Don't you have any problem with the mirror mode?
My screens get with vertical horrible lines...

Andyvand> How do you do those kernels extensions? I'd like to help community but I didn't find any kind of tutorial to try to understand how to edit them

krrr · #28 06-26-2010, 06:27 PM

I just used my LCD monitor as second monitor (which is extended space,I can move one window from 1st monitor to second) ,so no issues there. is this what you mean by mirror mode?

y333 · #29 06-26-2010, 07:43 PM

krrr> In fact this is extended mode

Your 2nd screen acts like an extension of your deskopt. I asked about mirror mode that is the mode where the 2 screens shows the same content

You could find the checkbox in the Monitors Settings (on the middle tab when the 2nd screen is connected): "Mirror Displays".

Take care, If you have some scratchy screen like me, when unplugging the monitor, you will be able to use your computer again but anytime you will plug the monitor again, you will see those beautifuls artifacts. To disable the mirror mode, you could use this tool from a terminal http://www.fabiancanas.com/Projects/MirrorDisplays/ (or delete your monitor preferencies). As a result you will be able to use your extended mode again

Andyvand> Could you juste have a look to my ROM (27A2.5D00.0003.vga.rom)?
