Hi! I'm newbie at OSX.
Sorry for my english is bad.

I have problem with install. When I set "OnChip SATA Type" to "Native IDE" I Can't find HDD in Installer, but when I set it to "AHCI" I can set at "OnChip SATA Port4/5 Type" to "As SATA Type" or "IDE", I set "IDE" and I can find HDD in Installer, install OSX, but it can't boot. Why I can't find HDD in "Native IDE" mode?
