Question

What is "SATA IDE Combined Mode" in my bios?

Asked by: yuhs

In the bios on my Asus motherboard there is a setting called "SATA IDE Combined mode" which is enabled by default.

I'm using 4 SATA drives in SATA mode (not RAID or EHCI) and have no IDE at all. Is there any reason this should be enabled? Will I pick up any performance by turning it off?

I doubt that you will get peformance if you disable it, but it wont hurt if you don't have IDE Devices
Sata IDE mode is equal to (SATA Compatible) mode in other BIOSes, which means that it keeps the IDE Controller online and detects IDE Controller connected devices during the POST Process.

Like i said, if you don't have IDE Devices, its safe to disabled it, then your SATA will run in enhanced native mode.

Caution required - if you change the SATA mode then your machine may refuse to boot.

This option is used to emulate an IDE drive so that older OSs such as XP/2000 can see the drive without the need to additional drivers.

My bios has a SATA/AHCI/RAID selection choice and then a completely different setting for the "IDE Compatability Mode".

I guess the IDE Mode is set to be universal out of the box. I like the sound of "Enhanced native Mode", I'll shut IDE mode off tonight to test. Thanks........
