Please upload your dsdt that you have modified for shutdown fix and then i will make it see and fix it to work.

And put into Extra folder in com.apple.boot plist system-type 2 which means that you are running laptop...not a desk PC.

here you go, modified dsdt :http://www.mediafire.com/?4m593lm454djmlu

Cheers

Thanks...but i see in ioregistry that evoreboot creates own instance and comunicate with mach kernel...so dsdt dumping when this kext is loaded will not touch dsdt...so no go.

I see that we from _PTS call Shutdown & Sleep (0x05) & (0x04), what works, but we call before Sleep(0x04) another function called PTS which is responsable for Restart (0x03).

So we need to google some restart dsdt fixed and post links here to compare this dsdt and then we can make restart fix.

Function that we search in dsdt.dsl is PTS and must have if (LEqual 0x03) which is call to Restart funcion.

Here i would like to share my DSDT and files that i have modyfied to be put and running Mac OS X Snow Leopard 10.6.8.

DSDT.aml has integrated folowing patches
- Nvidia Graphics Card injection (NVidia GeForce GT120M)
- Audio Injection HDAC & HDEF (ALC662)
- Sleep & Shutdown patch (Its working Sleep and Shutdown)
- Some Cosmetic Renames (To be more Mac compatibile)
- HPET & TIMR & RTC fix ( to allow run vanilla MACH kernel)
- SpeedSteep Working (C2Duo P8400)
- WLAN injection (AR9285 working vanilla)

Currently is impossible to patch RESTART fix (it needs modyfied bootloader to reaad FASL.aml) so you need to use EvoReboot.kext

DSDT patching for Battery Meter is very difficul but is not impossible, so use AppleACPIBatterymanager.kext.

AppleACPIPS2Nub.kext and ApplePS2Controller.kext is needed to work keyborad and trackpad (Becuse real Mac does not have PS/2 devices only USB)

AsusK50IN.kext is used to inject pinouts when booting to make audio work( need bin patched AppleHDA.kext - just rename hex: 8508EC10 to 6206EC10)

fakesmc.kext is needed to simulate real Mac chip.

All is working flamlessy.

Here you go, download this files and enyoj

This goes to the first page
Thanks for the files buddy,

Cheers

Hi Flip, do you think it is possible to install Lion on a newly formatted hard disk without Snow installed? I found a .cdr image of Lion on torrent site and they said we just need to rename it to .iso and burn to DVD to install Lion without Snow. Will the BootCD work with Lion?
