2.6.6 Universal Serial Bus Ports
The system board is equipped with two headers, at locations J2 and
J3 on the system board, for external USB ports. USB allows data
exchange between your computer and a wide range of
simultaneously accessible external Plug and Play peripherals.
You must have the proper drivers installed in your operating system
to use these ports. Refer to your operating systems manual or
documentation.

Adding a Second IDE Hard Drive
When using two IDE drives, one must be set as the master and the
other as the slave. Follow the instructions provided by the drive
manufacturer for setting the jumpers and/or switches on the drives.
We recommend that you use Enhanced IDE or ATA-2, ATA-3 and
Ultra DMA hard drives be from the same manufacturer. In a few
cases, drives from two different manufacturers will not function
properly when used together. The problem lies in the hard drives, not
the system board.
Important:
If you encountered problems while using an ATAPI CD-ROM
drive that is set in Master mode, please set the CD-ROM drive
to Slave mode. Some ATAPI CD-ROMs may not be recognized
and cannot be used if incorrectly set in Master mode.
