Everything works natively except SATA.
SATA works after installing ApplenForceSATA.kext
IDE 0 & 1
SATA All Ports, including e-SATA and PCI-E SATA
All USB Ports work
havent tested PS/2 ports, but they should work fine
SATA does not work until you've patched it. you can not install directly to SATA.
I have the same mobo,
i gave up trying to install on SATA (wmare seemd kinda complicated - i allready had a 200g WD IDE)
everything works but Hdd transfer is incredebly slow, max 3.4m/s (tested with xBnech)
so from all the threads i've read this seemed like a "no UDMA" situation;
i've been spending the last weeks on insanelymac and all over the places all mighty google took me, and the only "solution" i stumbled on was the AppleOnBoardATA.kext that zappadoc posted on insanelymac forum, but the link is not active anymore - so i searched for it in other places - found it on a korean forum but it was named AppleOnboarPCATA.kext, after i installed it - "waiting for root device"
i'm new to OS X - so be gentile :D
