EP41-UD3L with 10.6, Detailled how I did it (WIP) Options

[theBrave]

I mainly followed the tutorial at LifeHacker to get to an complete install.

Items needed:

• An 8GB-or-bigger USB thumbdrive
• A working machine with OSX 10.5 or latter
• The SnowLeopard DVD Installer (It only cost 29 $/€, so buy it, plus you get an Apple sticker)
• A working computer with the EP41-UD3L mainboard (duh)

Now, read the previous LifeHacker article.

What changes:

• Don't use (yet) Chameleon for the boot file, I didn't manage to boot properly using the RC3
• Don't use the 889 kext.
• Stop doing what is says before "Final Tweaks"
• When creating the bootable USB key, use my DSDT.aml file.

The DSDT.aml fixes:

• That the settings are corrupted at each boot
• That the sound pane hangs / Now the soundcard is maked as builtin
• The ethernet card shoul now be built-in
• Sleep

What you obtain:

• Maybe problems with graphics
• No sound
• Lot of "CFGetHostUUIDString: unable to determine UUID for host. Error: 35" errors everytime you type something on the console

Then:

• Using the exact same steps than for the USB key, I installed the same 10.1 EFI bootloader on the harddrive.
• Copy my DSDT.aml to /Extra

Then:
Using EFI Studio, add the EFI strings for your graphic card in /Extra/com.apple.Boot.plist

This fixes (at least for me, Fanless nVidia 8600 GT 512 MB):
Video acceleration + OpenGL

Then:
Using Kext Utility, install the LegacyHDA from the zip file
I used ./series of LegacyHDA 888 (ALC888)/4outs2ins HDA headphone/LegacyHDA.kext

Now the sound shoud work

Then:

• Use one of the methods to solve the CFGetHostUUIDString from http://forum.voodooprojects.org/index.php?topic=250.0

Now I need you for:

• I'm pretty sure that futher edits to the DSDT file could solve the sound problem without Kext (The Kext only contains a .plist file)
• I didn't had the DSDT file until the end, so thinks could work better than advertised, tell me so

I combined your guide with the others, and I wrote it down on my blog http://antariksa.web.id/blog/?p=296 ...

your DSDT works well .. i just put the LegacyHDA.kext at E/E to make sound works .. so the installation is fully vanilla, not touch anything on S/L/E ...

sleep works well .. but with the help of sleepenabler.kext

Somehow i can´t get the sound working

I used the kext you provided in your guide but i still can´t choose an output-devise

hi fetos ...
did you also use his DSDT.aml ?

AFAIK DSDT.aml only = sound not working; AppleHDA.kext only = sound not working; DSDT.aml + AppleHDA.kext = sound working ..

Yes i used his dsdt.aml file, its still in the extras folder.

I used the linked LegacyHDA.kext, should i rename it to AppleHDA.kext ?
