Only get 10.6.4 to work

The title pretty much says it all - anything above will simply not work. But I want to unleash the Lion on the hacky. Can anyone help me out?

Does nobody have any help? Or am I in the wrong sub-forum?

After using the combo updater, all that happens is that the baby gets stuck and I have to do a whole rebuild.
I was going to buy an SSD anytime soon anyways - so maybe I'll get that first, do a fresh install on it and then try my luck with it. If it doesn't work, I can make use of it as a video drive...

But maybe someone out there knows why the combo update always leads to system failures? (I know this is going off topic I had asked the question elsewhere before without providing sufficient info - to stop derailing this thread here, if you can help with the update issue, feel free to post here: Only get 10.6.4 to work)

The OS version specific sub-board is the place I would be asking this question. Also people will be more likely to have experience with some of the older hardware like you have.

When I asked for more than just "it fails" I was looking for information on when and where it is failing and what it is doing at the time it fails. Is it failing when you go to run the installer, while it's updating, after it updates...

What updates have you tried? 10.6.5? 10.6.6? 10.6.7? 10.6.8?
Have you done this in safe mode?
Single User mode?
What are your boot flags?
Are you using a DSDT? Where did you get it from?

It's actually been a while since I last tried. But as far as I remember it failed when trying to reboot.
I never used anything but iBoot and Multibeast, so I didn't change any DSDTs.
And no I did not try either single user nor safe mode (didn't know I had to)
I tried 10.6.5, and because I had to re-install everything again and again after trying, I didn't dare to try it again.

I am currently thinking about upgrading more than just the graphics card because I found out that an upgrade is probably not as expensive as I had thought.

Still any tips would be more than welcome. But before that, I think I'll follow one of the tips you already gave me, get a new HDD/SSD and clone the system and then try to update.
