I have Snow Leopard 10.6.7 installed but can only boot if I boot from my Nawcom DVD that I used to install SL using Retail Disk. I tried all combinations of boot commands possible including:

-v -f -x -force64 busratio=17 cpus=1 maxmem=4096 arch=i386

and no matter what I do I always get something along the lines of:

WARNING: ACPI_SMC_PlatformPlugin - getCPUIDInfo unknown CPU family: family...
-- power management may be incomplete or unsupported...
DSMOS has arrived
** Device in slot: SLOT--1 **
** Device in slot: SLOT--1 **

then most of the time that's all I get and it's just stuck there.

I have the latest BIOS update and I am using Darwin 10.7... the latest 10.6.7 kernel... and I tried to use the anVAL bootloader but I couldn't get it to work. I guess I just don't know how to do it.

Well I installed his legacy kernel so idk why it says darwin 10.7 but it does lol I will try that bootloader now.

Author Update #2 @durkmusic 2011-05-20

I did exactly what you said and it still doesn't boot. Gives same error.

Author Update #3 @durkmusic 2011-05-22

I did that and it didn't work still gave me that same error.

Author Update #4 @durkmusic 2011-05-23

HELP US!

and BMW3series, if you figure something out please DO NOT FORGET TO POST HOW YOU GOT IT WORKING! And if I figure something out I will post how I got it working as well. Thanks! (:

Author Update #5 @durkmusic 2011-05-23

So it's GPU related? Well I have a different GPU i have a 5770. What should I do?

Author Update #6 @durkmusic 2011-05-24

When I go to about this mac it stills says darwin 10.4.0 is being used. Does this just not update? I downloaded 10.7.0 and updated for 10.6.7. The package installs itself yet it still says 10.4.0 in the about this mac window. Is it updated or not? Thanks.

Author Update #7 @durkmusic 2011-05-25

We have almost the same exact specs besides the motherboard akimoa. What did you do to install leopard? I think my problem is I'm installing 10.6 retail and updating straight to 10.6.7 via software update.

Author Update #8 @durkmusic 2011-05-26

Tried that and it installed, but when I went to boot with the boot cd it won't work no matter what boot flag I use. I'm going to try and boot with nawcom after work and see if I can get it booted. If not, I will install with nawcom, then follow the tutorial once I get to the desktop.

Author Update #9 @durkmusic 2011-05-27

Here is what I did:
followed tutorial in link above. When I rebooted after install I used nawcom boot cd instead of the one they gave. Followed tutorial from then on. Did not update yet. Had to instal realtek kext to get internet working. Updating system now.

Updating did not work. Even after legacy kernel. Gave me same error I was having before. I am going to keep it as 10.6.5 because it works perfectly fine WITH full gpu support. I wish I could software update to 10.6.7 but it is just not working for me. If someone knows of a solution please let me know. Thank you.

Author Update #10 @durkmusic 2011-05-28

I'm really new at this stuff could someone explain that to me? I have no clue what he said lol

Field Note #1 @akimoa 2011-05-18

Dude using a Darwin Kernel in AMD isnt very clever go for nawcoms Legacy Kernel
and be shure once u get in there with the mod cd u install a Bootloader wich detects the vervet framebuffer(kabyl) This one does (cl .ly/0I0i2h3b160l09260C2s) correct for your card and solved your problems are

Field Note #2 @akimoa 2011-05-19

try with the bootflag

 -v legacy_kernel arch=i386 busratio=17 

and if u get in there u apply these settings to your com.apple.Boot.plist

Field Note #3 @maya77 2011-05-20

Boot using your CD, then install legacy kernel and Chameleon.

Here is latest Chameleon build:
k exts.com/view/1251-chameleon-2.0-rc5-r851.html

And here is legacy kernel for 10.6.7:
k exts.com/downloads.php?do=file&id=1062

I'm also using VoodooTSCSync for my AMD:
osx 86.co/f36/amd-dual-core-optimizer-for-snow-leopard-t6820/

and following kernel flags:
arch=i386 -force64 cpus=6 busratio=16

"cpus" and "busratio" values for your CPU are 4 and 17.

Field Note #4 @BMW3series 2011-05-23

I found why it was happening.
GPU must be enabled.
I reinstall Mac OS X 10.6.3 and enable my video card with efi string (nVidia 9800 GT)
Then I update to 10.6.7 and instal legacy kernel.
Now system boot normally.
Sorry i don't speak english very well

Field Note #5 @akimoa 2011-05-25

just be sure u assign legacy kernel as default in the com.apple.boot.plist in extra folder and it should use it

Field Note #6 @akimoa 2011-05-26

Use thisTutorial ↗ and u should be fine also combine it with common sence

Field Note #7 @k-loz 2011-05-28 ↳ Re: @durkmusic

i had the same problem with 5770

i had the same problem, solved using Chameleon-2.0-RC5-r832 installer in customize i installed klibc from modules tag, also i had Leopard installed in a second partition which i deleted when reinstalled Snow Leopard that two changes i made worked for me
