As it turns out i was able to figure it out myself.
I think once i get an optimum dsdt i'd like to build a patched bios and flash my motherboard.
Well done. As for flashing your motherboard with a patched BIOS, you can if you like buy why bother now we can override DSDT with the latest bootloaders?
Have one parent 10.5.8 disk and one clone 10.5.8 [identical copy of parent] where I want to install upgrade to SnowL.
Installed Chameleon on both disks [RC3], and configured the /Extra directory on the clone with teh kexts and .plists according to the detailed guide and my system.
On reboot the system hangs at:
ACPI_SMCPlatformPlugin::start waitForServiceMatching(AppleIntelCPUPowerManagement) timed out
I have never tried to upgrade to Snow Leopard from Leopard, only a fresh install. As you have installed Chameleon RC3 on both HDD's are you selecting the correct HDD (the clone) in BIOS to boot from? Sounds like the system is not finding fakemsc.kext.
This DSDT blows me up! It was excellent without it! PCI card worked in PCI Slot 1 and the speed was high. And rebooting worked! Why DSDT! Stupid Clock Step! Why they wrote 4 instead of 2?
Er... is it the only reason to use DSDT?
If your machine was 'excellent without it' then go back to what you were using before.. To get Snow Leopard up and running all you need is a basic DSDT patched with the CMOS reset fix as my DSDT guide explains. I used my Snow Leopard install perfectly for months with only the basic patched DSDT.
All the latest manual patching being done is just to get our hacks more mac like and to tweak our systems to work more efficiently and utilise the hardware better, like speedstep etc.. If you can't get it working then don't worry.
Thanks for the reply, I guess i will continue to run 32 bit till there is a reason to switch to 64bit. I think some programs still run in 64bit when running 32 bit? Activity monitor list some stuf as intel (64bit) others as as just Intel
BTW, all the crashes i was having, have seemed to go away after updating my bios to F9 (on GA p35-ds3l) running wonderfully now.
I will take a look at the front page I would like speedstep to work too, but dont think it works with overclock anyways...
Yep. Most 64-bit apps will run perfectly well when you boot your kernel in 32-bit mode so you really don't need to use 64-bit mode.
Good news you have a stable system now you have updated your BIOS. And for SpeedStepping, you might be able to use it with an overclock, but I recommend reading FormerleyKnownAs' Vanilla SpeedStep
