Your last sentence just means the OS drivers work and can see the drives. but 
you need your BIOS to see the drives in order to boot from them.

Usually, there is some BIOS on the SATA card that gets loaded, similar to a 
SCSI card.

I use a SuperMicro SATA card, and the system sees the drives and boots from 
them, but it's a SuperMicro motherboard so it's designed to work with the 
card (or vice versa).

Depending on your SATA card, there might be a jumper or something that tells 
it to try and load its BIOS.

Try looking up the docs on your mobo, there might be information about booting 
from a plug-in card. It might be under something like "booting from SCSI".

Also make sure you have the latest BIOS installed in your motherboard.
