I create my DSDT.aml by

Create a .bin file with Everest's DSDT tool in windowsxp (same computer with my Leopard) >> Create a .dsl file with ACPI patcher02beta5 >> Create DSDT.aml with fixes and patches.

After that, I put my DSDT.aml to my EFI root, or /Extra/. It seems that the DSDT.aml does not work at all. The MacOS still boots as before, same boot message with -v flag. And still USB, Video card, Sleep not work well.

I don't see any difference.

What's my problem?

My spec:

MSI K8N Nforce4 motherboard
AMD64 x2 4600+
Nvidia 6800GT 256MB PCIE
Chameleon V2 RC2.0
Retail Leopard 10.5.6

kexts in my /EFI/Extra/Extensions :
AppleACPIPS2Nub.kext
AppleNForceATA.kext
ApplePS2Controller.kext
dsmos.kext
IOATAFamily.kext
SMBIOSEnabler.kext
System.kext

I can't figure it out, please help. Sorry for my English.
