The 25-pin connector is used to connect an external parallel port. The parallel port connects
your PC to a parallel printer. It supports SPP, ECP and EPP.
SPP
(Standard Parallel Port)
Allows normal speed operation but in one
direction only.
ECP
(Extended Capabilities Port)
Allows parallel port to operate in bidirectional
mode and at a speed faster than the SPP’s data
transfer rate.
EPP
(Enhanced Parallel Port)
Allows bidirectional parallel port operation at
maximum speed.

SATA 1
The Serial ATA connectors are used to connect the Serial ATA device. Connect one end of the
Serial ATA data cable to a SATA connector on the system board and the other end to your
Serial ATA device.
The power cable must be connected from the system board’s Serial ATA power connector to
the SATA drive’s power connector in order to provide power to the drive.
BIOS Setting
Configure the Serial ATA drives in the Advanced submenu (“SATA Confiuration” section) of the
BIOS. Refer to chapter 7 for more information.
