Serial ATA Ports

Six Serial ATA Ports (I-SATA0~I-SATA 5)
are located at JS1~JS6 on the motherboard.
These ports provide serial-link signal trans-

tional Parallel ATA. See the table on the right
for pin defi nitions.

Three PCI-Express (Gen. 2) Slots are located
at SXB1/SXB2/ SXB3 (J1~J3) on the mother-
