2.12 Onboard Headers and Connectors
Onboard headers and connectors are NOT jumpers. Do NOT place
jumper caps over these headers and connectors. Placing jumper caps
over the headers and connectors will cause permanent damage of the
motherboard!
Serial ATA2 Connectors These four Serial ATA2 (SATA2)
(SATA2_2_3: see p.2, No. 13) connectors support SATA data
(SATA2_4_5: see p.2, No. 14) cables for internal storage
devices. The current SATA2
interface allows up to 3.0 Gb/s
data transfer rate.
Serial ATA3 Connectors These four Serial ATA3 (SATA3)
(SATA3_A0_A1: see p.2, No. 11) connectors support SATA data
(SATA3_0_1: see p.2, No. 12) cables for internal storage
devices. The current SATA3
interface allows up to 6.0 Gb/s
data transfer rate. If the eSATA3
port on the rear I/O has been
connected, the internal
SATA3_A1 will not function.
Serial ATA (SATA) Either end of the SATA data
Data Cable cable can be connected to the
(Optional) SATA / SATA2 / SATA3 hard
