I am booting snow with Standard Chameleon RC2. No kernel panics at all. What's the point for using the netkas PCEFI 10.1 or 10.2?

Thanks DocShadow looks like r640 is the culprit. I been trying to figure out this Kernel Panic for a couple of days. Changed my boot back to r431 and no KP.

Me too...

some people gets kp on r640 some don't
i have figured out that some kexts on the extra folder gave me kp such as ataportinjector, other than that it works just fine with dsdt on extra folder

I have Snow leopard working perfectly with r640.
I had the same kernal panic problems but then manged to install using PCEFI V9 and then installed from within SL to new hard drive using r640. The install went perfectly and I now run 10A432 in 64bit mode with only one issue which is sleep and i've not even looked into that because it's not something i'm overly bothered about.

What i'm saying is that I don't think r640 is the problem, allthough I don't pretend to be an expert.

I'm not at my home pc at the moment but will post the guide I used along with the files needed.

Only 4 kexts used by the way.

Cheers.

PS - My signature says 10.5.8 but that is on a seperate drive. I didn't use the EFI partion with Snow Leopard but will be moving files there when i get some spare time.

any chameleon2 based loaders has panic isue when mkext and kext permission is incorrect.
but with right system cache chameleon 2 work's with 10.6 okey,so if you install via OSInstall.mpkg do repair permission and rebuild cache.
only PCEFIv9 can boot SL with wrong mkext or with -f.
sadly old chameleon 1.011 sources are unavailable.(
