If you'r in Berlin I guess we aren't that far off (in time that is), I'm in UK now (and that's why I can't be of much help).

hi again,

ok, i tried with cd boot with no success and now i try again with usb stick... can't find mach_kernel at the moment...

i'm from mannheim btw ... but time is like in berlin ^^

edit:
i editet boot.plist to -> hd(0,2) mach_kernel ... now it boots from install dvd i guess ... currently at "System uptime in nanoseconds: ... " --- seems like a crash, but i hope i'm wrong ^^
-> ok, that's a kernel panic in text mode ^^

edit2:
i think somehow my mainboard is broken ... ... maybe i try a new asrock or maybe a more compatible one... is there one?

Have you tried Windows/Linux? If those don't work either, that yes, it's probably the motherboard.
It should never be hd(0,2) mach_kernel using a USB stick with Chameleon, unless the kernel is on the same partition as OS X. Chameleon sees it's own disk as 1, so the disk listed as disk0 in disk utility is hd(0 in Chameleon.
Is the KP the same one?

hi...
yes win7 x64 did run well ... though some installation issues with a raid card; so normally the board should be ok. but, after a "soft off" the bios doesn't boots correctly and there is no video output. if i pull off the power cord and put it back into the power supply the pc starts correctly. so one out of these two components is defect i guess... however i maybe change the board tomorrow, but first i would like to try exactly your bios settings if this is possible...

or someone else reading haz a asrock x58 extreme?

the hd(0,2) error was with a selfmade bootstick with one gpt partition. i'm still confused what really is necessary and what are the steps to make a good mac-os-install-usb-stick.

but, it seems that the KP has to do with the radeon 4870. netkas.org seems to be the right point of informations about snow leopard and radeon cards, but i'm still not sure what to do. there is a guide which tells me to set -x flag oder -pci0 flag, but still same KP.

so long. thx for staying with me

edit: -x means boot in safe mode. didn't help me woth several versions of empire efi (including legacy 1.085 f.e.)

Yeah, sorry I can't help . I deffinetly should write that guide, so many people seem to fail, and it's beacouse of what a bad "helper" I am. I'm more of a "hands on the problem" guy, so maybe it's that... oh well, good luck with your RMA (I had to do one my self, and it's no where near as bad as I expected!

... no no, you're a good helper.
i try a different grafics card today and maybe tomorrow change the mainboard.

thx so far, will post my results.

edit:
changed radeon 4870 to a geforce 6200 ... boots fine and installation fails at the end. (seems normal that there is a error message at the end of the installation process ... system boots )

so for my understanding: you have a usb boot stick to boot your OS with the dsdt file etc on it?

Hi again,

finally my system works. i changed the ati radeon 4870 to a geforce gts250. Thanks to you, adriangb, i have sound too

hardware:
asrock x58 extreme
core i7 920
6 gig ddr3 ram
geforce gts250
2 * sata raptor 10000rpm
LG dvd burner (sata)

BIOS Settings:
everything to AHCI, disable eSATA
CPU Config, everything enabled, C6 State, Version 1.9

what i've did:
1. burn Empire EFI 1.08 i5/i7 CD
2. Change CD to Leopard Install DVD
3. Installation complete and reboot (with Empire EFI)
4. Install Updates to 10.6.2 (via USB Stick) and reboot (empire efi again)
5. install myHack 1.0 Final Release with default settings
6. change com.Apple.Boot.plist in /Extras entry: PciRoot from 1 to 0
7. get archive.zip from adriangb and copy dsdt.aml to /Extras and kext to /Extras/Extensions
8. download, install and use pfix 3.0 from same homepage where myHack is from
9. reboot & done

niiiiiiiiiiice!!!!!!!!!!!!!!

I'm happy to see you got everything working

hi again,

did you get managed to get speedstep and standby working? and can you maybe upload your uncompiled dsdt file that i can play a little bit with it?

thx in advance

ps: performance is great... for example from local raid 0 (2 * 74gb raptor) it plays smoothly 10 movie trailers in 1080p simultaneously

Speedstep yes, sleep no. Can't you uncompile it yourself? I don't have my DSDT with me, and I wont until I get my pen drive and own computer with iasl (tomorrow). And I can't test if it uncompiled well or anything!
Sorry.
