I don't know about Abit but for p965 boards not all sata ports work for install, if I am not mistaken only first 2 sata ports of the 4 will work initially to install but you will not get the Apple logo. Unfortunately I am rusty and don't remember all the issues. There is a thread for the Abit motherboards at insanelymac that will be useful. There are other things like bios settings, ahci that can make a difference.
