Hardware Installation
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.
2.7.6 Universal Serial Bus Ports
The system board supports 4
USB por ts. 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 the USB ports. Refer to
your operating systems manual
or documentation.
Two onboard USB ports (J3 -
Black) are located at the ATX
double deck ports of the board.
The J23 connector on the
system board allows you to
connect the optional 3rd and
4th USB ports. These optional
USB ports, which are mounted
on a card-edge bracket, will be
provided as an option. If you
wish to use the optional 3rd
and 4th USB ports, install the
card-edge bracket to the sys-
tem chassis then insert the
connector that is attached to
the USB port cables to J23.
The USB ports cable connector can be inserted only if pin 1 of the
cable is aligned with pin 1 of J23.
