Stuck at Apple logo screen (with Biostar TP45HP)

@tham50add a timeout string to the boot.plist then boot with -v

Thank you for replying. How do I exactly do that?

I can't even boot to OSX hence I can't edit com.apple.boot.plist.

I reinstalled iATKOS and chose a different bootloader and I was able to do F8 and -v. Here is where it is stuck,

I spent half of my day yesterday trying to install on this rig but it seems it is just incompatible with hackintosh. I've tried installing iATKOS with IDE instead of AHCI in the bios, it will finish installing but upon first boot kernel panic occurs.

I think I made a little progress. With iATKOS v7 Vanilla Kernel, very minimal drivers, if I boot with -v -x cpus=1 it will take me to "no keyboard connected" although keyboard is lit. Maybe a PS/2 kext is the fix. If I boot with -v cpus=1 I could here music but it is stuck somewhere. I guess it is pretty close to have a go.

SUCCESS!

Reinstalled with Appleps/2.kext, extracted cpus=1 fix from iDeneb and she is working. Finally got it working.

DSDT GUI with New HPET option didn't fix it. I am using a bootloader other than EFI and Chameleon, I wonder if that's why it didn't work. I will try with Chameleon.

Chameleon screwed the install. I can't seem to get F8 to work with Chameleon, I pressed F8 as soon as my mobo logo came on up to boot option GUI but no go. Is there a trick to do it or it is not supported?

I will try the cpus=x next time and see how it goes. So far, I have re-installed and it is working ok.

Both cores are now working. I had to install chameleon first and run the DSDT. CPU speed is not correct though, showing 2.07 but it should be 3 GHZ (E8400).

It is working great except for there are times that I need to reboot/restart the rig 2-3 times to get to desktop. It will show the blue screen a little offset from the middle of the screen which tells me it will not boot to desktop.

It actually boots to desktop but takes longer. I just let it do its thing and it booted to desktop in maybe 5-7 minutes.

The long boot was actually caused by the ATI HD4850. I replaced the GPU with 7900GS and never had a failed boot again. Unfortunately, after updating the BIOS, iATKOS install was nuked. Reinstalled but it won't work with Chameleon v2bootloader even after selecting bootthink as initial bl and installing Chameleon afterwards. Weird.

I will try v3 later.

Even without DSDT, after installing Chameleon v2 rc2, it won't boot anymore. I will play with it again sometime today.

add a timeout string to the boot.plist then boot with -v

open /Library/Preferences/SystemConfiguration/com.apple.Boot.plist and add a new key named Timeout. type is String and value the timeout you wanna have.

are you dual booting? because If you are, go purchase MacDrive and you will be able to edit it. or Google for HFS+ drivers for windows.

@punk_zappaI can't even boot to OSX hence I can't edit com.apple.boot.plist.

boot using the dvd

Well, lunch the Terminal use "mount -uw /Volumes/<name>" command to have r/w access and edit the file using vi Editor.
You can also use Transmac for editing from Windows...

@punk_zappaextracted cpus=1 fix from iDeneb and she is working. Finally got it working.

This just adds cpus=1 flag to com.apple.boot.plist - I would try to compile a DSDT.aml using fassls GUI and the New HPET option and remove that bootlfag again, I daresay this could fix it, so that you're able to use both Cores.

Try booting with cpus=1 and DSDT=none.aml, maybe your patched dsdt doesnt work with the new bios, if they changed many things, its always advisable to use a patched dsdt based on the same source of your current bios version.
