The 'auto' or 'JBOD' setting refers to maybe only one hard drive, not matching pairs or a set of drives. Or if more than one hard drive is used. Should be a control line in a BIOS page specifically for IDE (PATA) and SATA controller activity.
Have you tried the AHCI mode? (AHCI stand for
Advance Host Controller Interface, may be required for SATA use.)
There may be up to six SATA ports, two as 'primary' and the others for RAID or other use. Check the user manual as to priority.
The logo on separate chipsets should appear as a silver color. If a brownish color, the chipset may have suffered heat damage.
The CPU has memory controllers on the die itself, but a remnant of the North bridge still controls other features. Usually has a heat sink on it. The South bridge also controls other features, normally no heat sink.
Have seen listings for that 1156 socket type on sites like New Egg, Amazon and eBay. Some "new", others "refurbished".
