auntyjamima said:Wow! Tony you are amazing! I have no idea how you do this, but I am trying to learn (still a total noob). Any chance of this dsdt for the i7 with speedstep?
Evildemon989 said:But anyways, thanks for this edit. Works for me with 10.6.2 AppleHDA.kext.
tonymacx86 said:Success!
You must update to the latest GA-P55M-UD2 bios (f7c) for this to work!
I've modified the ALC 888b code in the DSDT for the P55M-UD2 so that the LegacyHDA_888b.kext now works with the vanilla 10.6.2 AppleHDA! I just updated all of the files from the site- here are some links for all of you UD2 owners..
NEW GA-P55M-UD2 tonymacx86-DSDT-FIXES.zip
Includes updated GA-P55M-UD2 DSDT.aml with fixes for CMOS reset, UHCI/EHCI, IDE (SATA), PIC/TMR/HPET, SBUS, and HDEF.

This was a nagging issue for me, now the task of editing every file/guide that includes a DSDT for the 888b... Here's the code to replace in your HDEF section:
Code:Device (HDEF) { Name (_ADR, 0x001B0000) Method (_PRW, 0, NotSerialized) { Return (Package (0x02) { 0x0D, 0x05 }) } Method (_DSM, 4, NotSerialized) { Store (Package (0x0A) { "built-in", Buffer (One) { 0x00 }, "codec-id", Buffer (0x04) { 0x88, 0x08, 0xEC, 0x10 }, "layout-id", Buffer (0x04) { 0x77, 0x03, 0x00, 0x00 }, "device-type", Buffer (0x10) { "Realtek ALC888b" }, "PinConfigurations", Buffer (0x28) { /* 0000 */ 0x10, 0x90, 0xA1, 0x01, 0x20, 0x90, 0xA1, 0x02, /* 0008 */ 0x80, 0x30, 0x81, 0x01, 0x90, 0x40, 0x21, 0x02, /* 0010 */ 0x30, 0x40, 0x11, 0x01, 0x40, 0x40, 0x01, 0x01, /* 0018 */ 0x50, 0x60, 0x01, 0x01, 0x60, 0x20, 0x01, 0x01, /* 0020 */ 0x70, 0x61, 0x4B, 0x01, 0xA0, 0x01, 0xCB, 0x01 } }, Local0) DTGP (Arg0, Arg1, Arg2, Arg3, RefOf (Local0)) Return (Local0) } }
