Two USB ports are available for connecting USB devices.

7) Primary / Secondary IDE Connectors
(40-1pin PRIMARY IDE/SECONDARY IDE)
These connectors support the provided IDE hard disk ribbon cable. After connect-
ing the single end to the board, connect the two plugs at the other end to your hard
disk(s). If you install two hard disks, you must configure the second drive to Slave
mode by setting its jumper accordingly. Refer to the documentation of your hard
disk for the jumper settings. BIOS now supports specific device bootup (see Boot
Sequence in 4.6 Boot Menu). (Pin 20 is removed to prevent inserting in the
wrong orientation when using ribbon cables with pin 20 plugged).
TIP: You may configure two hard disks to be both Masters with two ribbon
cables – one for the primary IDE connector and another for the secondary IDE
connector. You may install one operating system on an IDE drive and another on
a SCSI drive and select the boot disk through Boot Sequence in 4.6 Boot Menu.
