GA-P55A-UD3 2.0 F11

[onastvar]

Was anybody able to install Snow Leopard on GA-P55A-UD3 2.0 F11 motherboard. I tried with 3-4 different versions of iBoot and non seem to work. I'm using retail Snow Leopard DVD. I also tried to boot with ATI HD 4670 & NVIDIA 9800 GT same issue. I tried safe mode, no luck.

I cannot get MAC OS to install. I get a screen with a stop sign (similar to non-smoking sign) and it's stuck there for more than 30 minutes. I made sure bios setup is same as it shows on iBoot+MultiBeast latest Guide. I tried also with P55 iBoot same issues.

Any suggestions. Thanks!

SOUNDS LIKE AHCI NOT ENABLE ,FIRST BOOT CD ,POWER S3 AND HPET= 64BIT

BETTER TRY AGAIN WITH 9800GT
