I've been getting the same error-code since I built my computer, but it works fine(so I just ignore it). Got two drives, one SSD another HDD. Both SATA. Both connected to the Intel controller ports, the other controllers are disabled in BIOS.
"A0 - A7 Problem related to IDE or SATA devices. Please re-install IDE and SATA devices. If the problem still exists, please clear CMOS and try removing all SATA devices."
Haven't bothered to try that.
