Unknown AHCI Controller after updating to 10.6.8

[Guest]

Hello!

Firstly, my spec:

 

1. Asus K50IN-SX152

2. Intel® Core2 Duo CPU T6600 (SSE 2, SSE 3)

3. MCP79

4. -

5. NVIDIA GeForce G102M

6. ALC662

7. Realtek RTL8111/8168B

8. Broadcom BCM4321

9. SATA HDD

10. Touchpad and keyboard: PS/2

 

I've got this up and running 10.6.7 with SpeedStep, sleep etc. and correct information showing under Serial ATA in System Profiler: MCP79 AHCI Controller. Unfortunately after updating to 10.6.8... it went crazy and now I can see only: Unknown AHCI Controller. I have no idea what to do about it, tried with AHCIPortInjector.kext and various Chameleon versions, hoping it would help - with no luck...

 

More information:

</plist>

 

DSDT: Deleted Aliases in CPU section, Darwin in OSYS method, IRQ deleted in PIC (to fix DVD-ROM issues), SMBUS. That's all.

 

Thanks in advance...

try these 2 Legacy AHCI kexts .

 

AHCInamefixes.zip

 

They are safe to use and dont conflict with others; put them in /S/L/E or in /E/E, repair, reboot and see if this fixes the issue. For me it does.
