Confirmed working on MSI K9N6PGM2-V2
 

10.6.3 only - update to 10.6.8 a lot things fail

Have to use PS2 keyboard, because legacy USB is disabled in BIOS.

Used ATA HDD and DVD-writer. SATA HDD works fine as well.

Must use add-on PCIe card and make QE/CI fully functional. I use 8400GS 256MB, and have to use following kexts (EFI strings, GraphicEnabler not working):

There is boot up delay due to IOATAfamily. But if using a fixed version, sleep/wake up would not work. System can wake up, but disk0s2 disappeared and must hard reset. Default IOATAfamily, sleep/wakeup works perfectly.

Only problem is slow USB. EHCI speed at 1-2 MB/s. Still searching for a fix.

USB problem
 

At first sorry for my little English proficient way to explain my problem.

I have a plate-VSTA Asrock AM2NF6G 2 gigs of memory and ATI video though and installed OS X as you indicate I did not recognize USB devices when inserted, the keyboard and mouse yes, but the rest of the insert peripheral ahunque not before I have a boot error or something to add.
If possible you can tell me I have to do.
Regards and Thanks .. :(
