GA 770T UD3p and ATI HD4860 troubles, pls help.

[Ryu Hayabusa]

My PC is GA 770T UD3P rev1.0, AMD x4 620, Adata 1333 2GB, dataland ATI HD4860 512M/256bit DDR5(inferior product for ATI HD4890 which only sold in China Mainland). After many tries, i successfully install the 10.6.3 Retail(10D578) on my PC. My steps are(under windows 7):

1. Use HFS explorer extract need file and save as iso. and use a software write iso to a disk partition. Install macdrive and replace original kernel(use match_kernel.test7, this works for me)

2. Install bootthink. Firstly, it couldn't boot into snow leopard. I find some basic kexts and copy them to c:\darwin\system\librarySL\extensions. Then it can be boot. Here are the kexts:

***********************

AppleACPIPS2Nub.kext

AppleIntelPIIXATA.kext

ApplePS2Controller.kext

ATAPortInjector.kext

Disabler.kext

dsmos.kext

ElliottForceLegacyRTC.kext

IOAHCIBlockStorageInjector.kext

JMicronATA.kext

LegacyHDA.kext

NullCPUPowerManagement.kext

PlatFormUUID.kext -----> this and above are all unzipped from a shared package from network which says that these are basic kexts need for bootthink.

////////

fakesmc.kext ----->included in bootthink setup package

TotallyFixStillWaiting.kext ----->added later for startup(fix still waiting for root device issue)

EVOenabler.kext ----->added later for recognize the ATI card.

***********************

3. Install snow leopard on pc, after installation, "wait for root device" error occur, i found a "TotallyFixStillWaiting.kext" and put it into bootthink, then everything ok. It is lucky that ethernet card can work after installation.

-----------------------------------------------------------

When enter the system, i found some problems(I fixed the sound card, time conflict with window 7 problem by install some common kexts):

1. System couldn't recognize the CPU and memory, unkown cpu 2.7GMzh, 2GB 667 DDR2(should be 1333 DDR3). I change bootthink's file smbios__.plist(under c:\darwin\) to smbios.plist, in this file SMmemtype is 24(DDR3) and rate is 1600, after startup it show 2GB 1600 DDR3, but i don't known if the memory is really running as 1600 under snow leopard? or 1333? or 667?

2. Couldn't get my video card work properly. Resolution ratio couldn't be changed, there is only "1024x768" in setting list. Snow leopard couldn't recognize the card. If i use EVOenabler.kext with bootthink, snow leopard show that my card is 4890 or 4870(different EVOenabler.kext). But the resolution couldn't be changed, I have to use "Graphics Mode"="1440x900x32" to force use the RES ratio i want. If i add dev id to ATI4800Controller.kext, the display monitor will lost connect with video card(it seems that display monitor is disconnect with the power supply).

Resolution ratio couldn't work, let QE/CI alone.

3. SleepEnabler.kext couldn't work, i tried at least 3 versions, none of them can work.

By the way, my partitions on disk are:

1 first partition NTFS primary Window 7

2 three partitions NTFS Extended other windows files

3 last partition AF Extended snow leopard 10.6.3

 

Can anyone help me with the three problem, thanks in advance.
