Thank you g_MAC
First of All!
Your guide is how most of the guides SHOULD be!
Back to my Retail Hackintosh.
I have succeeded to install SL on my x86 tower, running on a Gigabyte P35-DS3R.
Everything works fine except for the LAN part.
Somehow SL is not able to load the R1000.kext, so instead it loads the default RTL8169, I think.
So, no 1Gb for me, and sometimes that's a pain in...
I do not use the built-in audio, because my Hackintosh serves as DAW (Digital Audio Workstation) with Logic Studio 9.
Another issue I bumped into was that I could not boot my 10.5.8 Hackintosh anymore.
Using the Chameleon Boot Manager it just would not start.
So I just followed step 8 (on page 11 & 12 of the PDF version) of the "Gigabyte GA-P35-DS3 Retail Tutorial" by CaptainNemo (on InsanelyMac Forums).
And now I can boot both Leopards.
So, many thanks for your efforts (and CaptainNemo also many thanks).
You should be able to get the RealtekR1000.kext to load. Did you get Gigabit networking in 10.5.8?
Chameleon requires a different set of kexts to boot 10.5.8 to 10.6. What's CaptainNemo say about this?
