i think you're best bet (this is what i did). installer->snow leopard install->upgrade completely->multibeast.

what do you recommend for dual-geforce 9800? currently using nvenabler, which is fine, but not detecting the 2nd gpu.

For Radeon 4850: ATY_init or EVOenabler or both or nothing?
Thanks!

With the new 0.6, that's the perfect order. You can do it a number of ways, but I've enabled an option called EasyBeast, so that the first thing you do when you hit the desktop is install it- like so. Then you'll have a bootable system before starting to tweak anything else:

Tony,

This is so cool. I used CCC to make an image of my main drive, used the main drive boot to boot the clone, used MB to complete the clone and BANG! Perfect bootable clone in minutes!
MB has made me FEARLESS. - Thanks.

I am still having some issues after using Multibeast 0.6 with my i7 860 with GA-P55M-UD4. I have a booting 10.6, with no LAN, sound and will not wake from sleep.

I did install the RealtekR1000SL and 889a via Multibeast but they still do not work. My biggest issue is upgrading to 10.6.2 as I'd like to diagnose these issues there. I've tried 4 times to update to 10.6.2 and each time it kills the system and I have to reload the OS.

I've tried...

1) Use Multibeast, then apply 10.6.2 combo update and then reboot.
2) Use Multibeast, then apply 10.6.2 combo update and then use kext utility then reboot.
3) Use Multibeast, then apply 10.6.2 combo update and then use kext utility then repair premissions then reboot.
4) Use 10.6.2 combo update and then Multibeast then kext utility then repair permissions then reboot

All end the same way with it rebooting and on the way up Chameleon starts booting it fine then at the point the display goes blank to display the desktop, it instead reboots. Works fine (sans LAN, sound, sleep) at 10.6.

What is the proper method to upgrade an i7 860 with UD4, 10.6 OSX to 10.6.2? Please be step by step as the guides I have followed on here have not gotten me updated successfully. See above for what I've tried....

Thanks for any help you can provide!

Did you install the right DSDT file?
As that seems to be the bit missing

Yep, I installed the DSDT using Multibeast for my board (GA-P55M-UD4).

I am thinking of this next. Can someone comment on the sequence...

1) Boot CD/Install SL
2) Update via 10.6.2 Combo Update
3) Before rebooting, run Multibeast for all needed items
4) If not easy EasyBeast, kext utility/repair permissions
5) Reboot

Does this seems like the needed steps/sequence. If not, what would be the order?

Should I run Multibeast before the 10.6.2 upgrade as well? When running Mutlibeast after thr 10.6.2, do I need to select a replacement kernel if I have an i7 860? If so, which one?

THANKS again.

Personally, I believe you should get your system's hardware working before applying ANY update.

For instance:

Boot from Install CD
Flip to OSX Install DVD
Install (customise, core system only)
Reboot
Boot from Install CD
Select HD from BootLoader
Complete setup assistant.

Reboot
Boot from Install CD
Select HD from BootLoader

Check everything works.
Install Bootloader and Kexts (MultiBeast)
Reboot.

Boot from HD.
Verify - test hw/core software and use the system for 30-60mins to ensure its stable.
Does it all work? - Yes? (clone drive to another - I keep at least 2 working bootable OSX system disks in case something nasty happens [1] on USB and SATA)

Once you're happy; install 10.6.2. - Test via reboot. Then patch away.


[1] Like installing the 10.6 EFI, which broke my bootblock process in very odd manner.
