Many people use 10.6.4 when it comes to the DP55WP board, but I hate dealing with system updates on Hackintosh. So, instead I’ve installed 10.5.8 on my Hackintosh. First, Lets review what kexts we need for the DP55WB.
Audio-Realtek* ALC888-VC2-GR – AppleHDA.kext
Network-Intel® 82578DC Gigabit – AppleIntelE1000e.kext
Video-ATi HD 3870 (This is what I have installed) – ATY_Init.kext
Download Kext Zip file
You can do a standard install using Tony osx86’s guides, but I am unable to use those guides because this will be using a modified kernel on 10.5.8. So we have a vast array of custom kernels from people to choose from. Qoopz 10.5.8 Kernel worked great for me. I am using the iDeneb 10.5.8 teams build. Now for the build process:
Required startup options (Kernel Flags)
-busratio=20 (This will vary depending on which i5/i7 Core you installed. Click image below for the full list of busratios on all i3, i5, and i7 processors.)
[singlepic id=715 w=27 h=91 float=center]
-AHCI on SATA Connections
-Speedstep off (VoodooPower kext was giving me kernel panics)
OS Installation Options
–Chipset -> SATA -> AHCI
–Video -> ATI -> ATi_Init.kext
–Audio Fix (AppleHDA.kext Modification)
This will get you into the OS and from there you will need to install one more kext. load up the K7 Kext Helper tool and select AppleIntelE1000e.kext -> Install. Now you should have a fully working OSX 10.5.8.
Couple optional settings
Edit com.apple.Boot.plist to add the busratio=20 flag. This saves you from having to enter it every time you load up osx.
Local Time Package
Run the local-time.pkg that comes in the Mac Setup.zip file that you downloaded above. This will fix the dual booting time problem.
