The BIOS settings for every motherboard looks similar but never exactly the same. For that reason we can't tell you, command-by-command, where to go to find and make certain adjustments. Here are the settings you will need to adjust (or at least verify) in your BIOS to make your hardware hackintosh-friendly:
  • Disable Quick Boot
  • . You may have to look around for this, but we've often found this in a section titled Advanced BIOS Settings. Just look for a Quick Boot or Fast Boot option and ensure it is set to disabled.
  • Configure SATA as AHCI
  • . By default, your motherboard will configure SATA as IDE and you'll need to change this to AHCI. In some cases you'll be asked if you want to do this when you boot up for the first time. If so, choose yes. If not, go into your BIOS and look for this setting as you'll need to make the change for everything to work smoothly.
  • Change the Boot Device Order
  • . Your BIOS will default to a specific boot order, which means it'll look for a startup volume (where the operating system lives) in various places until it finds one. The boot order is the order in which it checks each location. In general, you want to set your optical drive to first boot device so you can easily boot to a disc by simply putting it in the drive and turning on your machine. The second item in the order should be the hard drive or SSD where you're going to install OS X. The order beyond that isn't terribly important and entirely up to you.
  • Adjust the Hard Disk Boot Priority
  • . Some BIOS settings pages will also have a setting called Hard Disk Boot Priority, which is used to identify which hard drive to try and boot from first if there are multiple drives in the machine. If you install more than one drive in your hackintosh, be sure to set the Hard Disk Boot Priority to the drive where OS X will be installed.
