Vanllia Speedstep DSDT Trick falied what`s wrong with it?

[kidalive]

Greetin`s guys. I followed the Vanllia Speedstep DSDT guide to patch my DSDT. After changing the PSS values according to the PSS Changer I patched `N` compiled it and put it in the root but I got a KP at start-up. I replaced with the previous one and it worked again. My CPU is Core 2 dual and I deleted the useless part but it seems still has sth wrong down there. Pls have a check of my DSDT and tell me what`s wrong with it. Many thanks.

Check, if you have AppleLPC.kext loaded, otherwise speedstep will not run.

 Looks like you've missed patch LPCB section:

Method (_DSM, 4, NotSerialized)
			{
				Store (Package (0x02)
					{
						"device-id", 
						Buffer (0x04)
						{
 							   0x15, 0x28, 0x00, 0x00
						}
					}, Local0)
				DTGP (Arg0, Arg1, Arg2, Arg3, RefOf (Local0))
				Return (Local0)
			}

 

 

Put this just after:

Device (LPCB)
		{
			Name (_ADR, 0x001F0000)

 

 

There is DeviceID 2815 = ICH8M. It is closest to your ICH8, supported by AppleLPC.kext

Of course You can't have any Disabler

 

 

Also use IORegistryExplorer and check if you have 3 positions that are marked red on the attached picture.
