can't boot after using multibeast

[ing3]

I've installed Snow Leopard successfully multiple times, but each time after running Multibeast, I can't boot to my desktop. It'll show the grey screen with the apple icon and the spinning circle, but will then restart.

This has happened a few times, so I restarted after installing but before running the combo update and Multibeast, and I could get to the desktop using the iBoot-ATI disc, so that's how I figure it was Multibeast. I can't even get back in through safe mode.

Any ideas?

Boot using the -v function and post what it halts on

Here's where it halts

ing3,

The ATI Sapphire Radeon HD 4850 is a Royal-PITA to get working on OSX... But it's doable.

Anyway, try booting with 'PCIRootUID=1'...

Good Luck,

Here's what I get when booting with "PCIRootUID=1"

I re-installed SL today. Ran the 10.6.4 update and ran Multibeast, only running UserDSDT and System Utilities tasks. Usually Multibeast would close on me, so I'd have to reopen it and run it, but this time it didn't-- thought that might've been a good sign.

Upon restarting, it wouldn't boot. It would freeze after it showed the grey Apple screen and the spinning wheel at the bottom middle. Tried booting with the "PCIRootUID=1" command and it said that I need to restart my computer by holding down the power button.

If anyone has a ATI Sapphire Radeon HD 4850 and successfully installed SL with the update, please let me know what you did; or even if you had a different brand video card but still the 4850, please let me know. I feel that I am so close to getting this done.
