Update to 10.5.6 , a few Questions

[Bettarg]

Hello Guys,

first , my Apologize for my bad English

I have a more or less stable IDeneb 10.5.5 System.
It is far away from be perfect , but its ok.

Now i want to try a update to 10.5.6 but need more information.
Lots of Threads i have read, but dont found the Answers i seek.

First , do i need a DSDT Patch ? Where can i find a Patch for my system?
Do i need a SMBIOS Patch ? During OS instillation i dont chose one.

Will i have problems with my Hardware in 10.5.6 ?

Here are my Computer:

Asrock 939DualVista Board, Opteron 170 CPU
RTL8201CL Networkcard
Ati X1950XTX Card
Onboard Sound , working with AzaliaAudio

Thanks a lot !

Best regards,
Dirk
