Firstly, i will try to make sure that i have the updated bios version 0506.
I will connect my three sata drives to the first three sata ports. If there is any sata optical drive, connect it to the last sata port.
Then i will go into the bios >> Advanced >> Configure Sata as IDE.
Save and Exit.
That's all - check in the bios if the drives are recognised as well.
If it is still not recognised, try one drive by one on the different ports.
