Voyn1x - This guide is excellent, and helped me get my g31m-e2sl box up and running with 10.5.7 quickly. A few notes:

• I was able to combine your guide with this one to allow me to boot from two 1TB drives in a RAID-0 arrray with Apple's sofrware RAID.
• The IOUSBfamily.kext included in your extra folder prevented me from installing VMware Fusion - I received an error at the end of the install stating that the postflight script had failed to run. Removing the kext, and re-running the script from the VMWare installer package fixed things. My USB devices don't work after sleep, but besides that I'm good to go.

Thanks again!
