Gigabyte EP45 UD3P BIOS F9 Guide - Snow Leopard

This guide assumes you have Leopard 10.5.6 running on one partition and requires only 1 sata hard drive. IDE DVD will work too. Any simplifications or better ideas are welcome. Follow all steps.

1. Disable AHCI in Bios as it isnt necessary. Install Leopard 10.5.6. I used iPC 10.5.6. Format your HD into 2 partitions, GUID. Call your 1st partition Leopard, your 2nd SNOW. Install Leopard on 1st partition. I used a 40gb sata hd with 2 partitions of 20 gb each.

2. Find a copy of SL10432 and download it. Find X58_Mobo_Patch_Installer_BETA_muzzle.nl.zip and download it here

Thanks digital_dreamer!

3. Download these kexts.

4. Mount the snowleopard_10a432_userdvd.dmg in Leopard 10.5.6. Let it verify to make sure there are no issues with the dmg. Navigate to /System/Installation/Packages/ on the dmg. Double click OSInstall.mpkg and install to your empty Snow partition. Make sure you Customize your installation and deselect everything except for Essential System Software. Install.Once Install completes do not restart! You can Close the installer however.

5. Eject/Unmount the Mac OS X Install DVD.

6.Run the X58 Patch by double clicking on RUN-PATCH_INSTALLER.


------------------------------------------------------
A. Leopard Partition. This may not be necessary...Dont know!

Select your Leopard partition.

Select 2: Install bootloader

Select 3 (PC-EFI 10 Based on Chameleon v2. Snow Leopard compatible)

Select 7 Patch DSDT and press y

Select 3 MAke LEopard partition active

Select 19: Exit the app or quit terminal
------------------------------------------------------

B. SNOW Partition. I am sure this IS necessary.

Relaunch the X58 Patch.

You will be asked: "You have a previously saved volume selection. IS this correct?" Select NO and then select your SNOW partition.

Select 2: Install bootloader

Select 3 (PC-EFI 10 Based on Chameleon v2. Snow Leopard compatible)

Select 7 Patch DSDT and press y

Select 5 and press y to instal kexts

Exit the X58 Patcher and quit Terminal.

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

7. Kexts

Install IOATAFamily.kext you downloaded to your Snow extensions folder. Just drag and drop and overwrite. This is the IOATAFamily from 10.5.8 with LegacyAppleIntelPIIXATA.kext in its plugins folder. Backup the original if you want.

Install LegacyJMicronATA.kext to your Snow extensions folder. This is for IDE DVD.

DELETE AppleTyMCEDriver.kext from your Snow extensions folder as this causes a kernel panic. Don't know why.

8. Repair the extensions permissions for Snow. Open Terminal.

sudo -s
chmod -R 755 /Volumes/Snow/System/Library/Extensions/*
chown -R root:wheel /Volumes/Snow//System/Library/Extensions/*

Note: If you add any other extensions later to try to boot Snow because somehow something went wrong (maybe your gfx card is hanging snow from booting) and you want to try to fix it from leopard you must repeat step 8.

9. Delete Extensions.mkext from your /Extra folders on your Leopard partition. This is because it contains ATY_init.kext and could mess up your Leopard gfx drivers if you are already using any other type of injector like nvdarwin or nvinject or efi strings. Trash it.

10.Reboot!!! When Chameleon comes up press any key, select your snow partition and boot with -v -x32

11. If you successfully booted go to step 13. If your system hangs at ACPI_SMC it is very likely your gfx card. Reboot into Leopard. Delete Extensions.mkext from your /Extra folders on your Snow partition. Reboot and try to boot Snow again.

12. Still no luck? Reboot into Leopard again! This time back up all kexts that start with ATI and NVDA and Geforce and AppleIntelGMA from your SNOW Extensions folder to a secure location, then remove them from your SNOW extensions folder and reboot. If you add these kexts back in later remember you need to follow step 8 again.

13. Fix BIOS reset - For those interested follow step 3 under Making it Work at link below but do it while booted in Snow...or just download my patched dsdt.aml and overwrite the file in /extra for both leopard and snow partitions. I recommend you do it yourself though and learn something.

So i got snow booted with -v -x32 flags and using a evga 8800gts g92 at 1680x1050 with netkas aty_init.kext....but when i try to run the DVD Player app i get:

there was an initialization error, a valid video device could not be found for playback (-70017)

Anyone else seen this?

Well i am trying to get snow leopard on my gigabyte ud3p. I followed the guide over at infinitemac here:

http://www.infinitem...d-on-a-pc-t3137

It seems fine, tries to load but then it hangs with an error acpi_smc_platform_plugin and some crap about appleintelcpupowermanagemnt.kext timeout. I tired removing it, but did nothing....same error everytime!

Anyone else have this problem and find a solution? So close!

OSX86 on MSI P7N Diamond
BIOS version 1.2
Core2Duo e6400 oc to 2.8 ghz
3gb ram
40gb Seagate 7200.7 SATA HD on internal nForce SATA
IDE DVD on nForce IDE
USB Mouse and Keyboard
EVGA 8800GT 512 Working at 1680x1050 QE/CI Hardware acclerated with EFI String device id 0x061110de (G92)

Required:

iPC 10.5.6 DVD
Use USB Keyboard and mouse.

1. Go to BIOS and load fail-safe defaults. Boot from DVD. Press f8 and boot using cpus=1 -v if it wont

boot normally.

2. Partition drive as you like with disk utility in menu at top.

3. Customize Install with ONLY these options:

voodoo kernel 9.5
applenforceata nforce drivers
forcedeth V variation (won't work but enumerates device, may not be necessary)
acpi fix
seatbelt.kext 10.5.5
uuid error fix
dsdt patch (first one in the list)


any apps you want, but definetly DSDTPatcherGUI. You will need this.

DO NOT SELECT ANY VIDEO DRIVERS AT ALL!!! I suspect many failed OSX86 installs fail because of gfx

drivers that work incorrectly or for some reason or another crash the system before it even boots. So

just get your system up and running first, and then add gfx later.

4.Skip DVD check.

5.After Installation restart and boot with -v -f. If it restarts, try cpus=1 -v -f. If you get a kernel

panic about ACPI_SMC_PlatformPlugin :: Start... error or some crap like that, do this:

Boot using cpus=1 -s . At prompt type:

CODE
*******************************************
/sbin/mount -uw /
cd /system/library/extensions
cd ioplatformpluginfamily.kext
cd contents
cd plugins
ls
rm -rf ACPI_SMC_PlatformPlugin.kext
ls
exit
**********************************************

6. Wait patiently for first boot. Might take ten minutes. If it is slow, the likely reason is that

something on the install is maxing out your cpu processor. Just wait and finish the setup.

7. When you are logged in for the first time, Open Activity Monitor to verify if your cpu is maxed out or

not.

8. If it is, open your Applications folder and run DSDTPatcherGUI. Select Apply DSDT Patch TO: and select

your OSX86 partition. DO NOT SELECT HPET OR ANY OTHER OPTIONS. This seems to fix the maxed out core and

also seems to enable both cores on my Core 2 Duo.


9. Restart and boot with -v. Booting should be much quicker now! Check Activity Monitor again to check

your cpu. Both cores working! Yay!

10. The only issue with the voodoo kernel is that restarting and shutting down leads to kernel panic.

11. You can try vanilla kernel now if you want, but you must use cpus=1. S3 sleep does work but only with vanilla.

12. Install your GFX drivers.
