The board supports those features if avaliable.
I've never head one of one that adds those features because the OS wouldn't have loaded them.
What in the world are you talking about?
The OS loads and uses features based on the drivers and hardware used.
The OS doesn't give a damn if its on the mobo or not.
Unless you are discussing an OS drive it will have no issues enabling such features at any time.
A SATA controller can be integrated into the CPU, northbridge, a seperate chip placed on the mobo, or is on a daughterboard.
The OS will initialize and control all of those types of controllers simultaneously if you have more then one (which is fairly common) and support whichever features each of them has as long as it has drivers for it, which it does.
The thing you should watch out for is that for a boot drive for windows OS you must select the settings on your controller (IDE, AHCI, or RAID) before installing the OS and that with a UEFI mobo instead of a BIOS one you cannot change them after the fact (due to the faulty way windows boots on UEFI), attempting to make any change between IDE mode, AHCI mode, and RAID mode on an UEFI boot windows will cause it to bluescreen on boot.
On a mobo running in BIOS mode you can change between those options within limits: windows will blue screen during bootup if you installed windows while it was in IDE mode and you try to enable AHCI or RAID on the controller to which the windows boot drive is connected to. Or if you installed it while configured as AHCI and you try to enable RAID on the controller to which the windows boot drive is connected to. Having it in AHCI mode during installation will allow freely changing between those IDE and AHCI and having RAID mode during installation allows freely changing between all 3 (unless you have an utterly ancient mobo that does RAID in IDE mode rather then AHCI mode in which case it will exclude AHCI).
These are all issues with the windows bootloader being stupid, and cause no limitations at all beyond that. If you add a daughterboard with these features then you can freely disable and enable those features all day long with no problems as long as you are not touching on them on the controller that has the windows boot drive plugged into. Likewise if you have multiple controllers (the majority of modern intel mobos have multiple controllers from different makes, the integrated intel one and a secondary one providing extra ports along with legacy ports)
Its only an issue if you install windows and then try to migrate it to a different controller with different capabilities because the bootloader can't handle this flexibility and windows blue screens on bootup repeatedly.
