I have a fairly vanilla machine, with the patched DSDT, and (if I remember right) only the audio kexts are located oustide of /S/L/E...

I also have a backup partition of my install I can try without risk...

But where would I begin??

What I did was installed on my partition to get everything right.  Simply "updating" your 10.5 install would break it and it would be a lot of work to fix.  Download the 64 bit kexts file, apply the cmos reset fix to your dsdt, and you should be good.  I assume you made the dsdt file with a dsdt generator or the such?  Use kext utility after booting with -v -x -f -x32 to repair.  After that you shouldn't get any kernel panics.

If you need any more help, let me know.

You mean I have to do a fresh install? I really don't want to reinstall hundreds of programs and such :/

Download the 64 bit kexts file

Which kexts need 64 bit files?

Yes, I made the dsdt with some patcher or the other... how do I put the CMOS reset on?

I myself tried installing Snow Leopard on a empty harddisk. I did this using the "open OSInstall.mpkg" method or whatever the name is When trying to get this booting I found out the combination of bootloaders and extensions I needed to boot Snow Leopard.

Then I could boot the Install DVD (after I copied it on a flash drive, removed the AppleIntelPIIXATA.kext from IOATAFamily.kext, and rebuilded the Extensions.mkext by first booting the installer with -f -32 -s and mounting rw, etc...).

Using the almost original Install DVD on flash, I just upgraded my existing system (on software raid). Then I used the same ticks I learned from the fresh install to get this upgraded system working... And I'm writing this from my upgraded system, so... It just works!

I would like to add to my own story that it really helped to have a working version of Leopard to get the fresh Snow Leopard version booting, and then it really helped to have a working version of Snow Leopard to get my upgraded system working

Hi again,

You're only going to need the CMOS reset fix if your BIOS keeps being reset on shutdown/restart.  If it isn't, then don't worry about it.  To decompile you DSDT.aml file, you a program such as iasl.

I would recommend installing snow on a separate hard drive or partition to figure out how to get it to work, then you could either transfer the applications, etc. over or you could do a clean install.

64 bit kexts: http://redirectingat...repare-yourself

I would use all of the included kexts except for the Nvidia enabler.  Use efi-strings in the com.apple.boot.plist file if you are not already using them.

Hope this helps.

Yes, I am using EFI strings for video...

For those 64 bit kexts, which can be installed in extra, and which need to be in /s/l/e?

you could run migration assistant to transfer everything from your leopard install to snow leopard after you get her running
