Legacy IDE vs. Native IDE

[lschmidt]

I'm wondering what the difference is here. I can set my SATA ports to operate as Legacy IDE, or Native IDE. I know for sure I don't need RAID (1 hard drive), and I don't want to use AHCI either. So that leaves legacy IDE or native IDE.

The only thing is I don't know the difference, I've searched forums and even google but I'm having trouble finding a definitive answer. I'm running Windows Vista 32-bit.

Any advice?

SATA Port0-3 Native Mode
Specifies the operating mode of the integrated SATA controllers.

Disabled Allows the SATA controllers to operate in Legacy IDE mode.
In Legacy mode the SATA controllers use dedicated IRQs that cannot be shared
with other device.
Set this option to Disabled if you wish to install operating systems that do not support Native mode, e.g. Windows 9X/ME. (Default)

Enabled Allows the SATA controllers to operate in Native IDE mode.
Enable Native IDE mode if you wish to install operating systems that support
Native mode, e.g. Windows XP/2000.
