Well, if you can get us the schematics for that QNAP TS-109 board, then perhaps we can figure out what controls that LED, and then determine whether or not it is possible to have it working with NCQ. Or maybe you can get Saeed Bishara (of Marvell) to investigate. There may be a standard LED control bit in the chipset somewhere that is known to internal Marvell engineers. Cheers
