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 three Serial ATA2
(SATA2_1: see p.12,
No. 11)
(SATA2) connectors support
(SATA2_2: see p.12,
No. 13)
SATA data cables for internal
(SATA2_3: see p.12,
No. 14)
storage devices. The current
SATA2 interface allows up to
3.0 Gb/s data transfer rate.
Serial ATA3 Connector
This Serial ATA3 (SATA3)
(SATA3_0: see p.12,
No. 12)
connector supports SATA data
cables for internal storage
devices. The current SATA3
interface allows up to 6.0 Gb/s
data transfer rate.
Serial ATA (SATA)
Either end of the SATA data
Data Cable
cable can be connected to the
(Optional)
SATA / SATA2 / SATA3 hard
disk or the SATA2 / SATA3
connector on this motherboard.
SATA2_3
SATA2_1
SATA2_2
Print Port Header
This is an interface for print port
(25-pin LPT1)
cable that allows convenient
(see p.12,
No. 20)
connection of printer devices.

USB 2.0 Headers
Besides four default USB 2.0
(9-pin USB4_5)
ports on the I/O panel, there are
(see p.12,
No. 18)
two USB 2.0 headers on this
motherboard. Each USB 2.0
header can support two USB 2.0
ports.
