Author Update #4 @gamingfusion 2009-10-14

OK that worked i got booted but then i got another kernal panic.

This time its the CPUPowerManagement.kext but i cant seem to find a downlaod for a Snow Leopard one,

Know of a download for one?

Author Update #5 @gamingfusion 2009-10-14

ok i got that problem fixed it was a bad kext file again.

Now it boots fine but when you get to the GUI, I can move my mouse but i cant interact with the interface.

Im really not sure what this is.

Unstable startup

I installed SnowLeopard last week and i have great problem with the startup. here are the problems i am having.

- nullCPUPowerManagement.kext not working(having to replace kext and repair permissions before almost every startup)

- Slow

- always need to use verbose

Author Update #8 @gamingfusion 2009-10-20

well i found out that the reason why it didnt work.

Its because the startup is slow. after about 3 or so minutes it starts to work. but what weird is that its still loading up apps like skype or the SL install disc.

Field Note #1 @thorazine74 2009-10-12

Did you put the patched compiled DSDT.aml in /Extra or in the partition's root?
Also why it doesnt work? There could be many reasons why SL doesnt boot apart from missing a patched DSDT.

Field Note #2 @thorazine74 2009-10-13

You may have found the issue described here ↗.
Try to fix it with kext mentioned there or if you have the sec. IDE channel disabled try to re-enable it in the BIOS.

Field Note #3 @Soobie 2009-10-18

Gaming Fusion I am on the same quest as you Installed SL yet not that stable as yet. No QE/CI have just tried the SilentNatit.kext and it pulled the graphics right then gave a KP and that was that.

Try a search for Macinized for how to patch your DSDT.

Any joy let me know.

Please post details about your graphics hardware and what method you used to get it supported.

Field Note #5 @spalek83 2009-10-24

i thought you were supposed to put dsdt.aml in /

or root in other words. is it supposed to be in /Extra ?
