Please note that the pins of VCC & GND must be connected correctly or it may cause some
damage
Serial Port Connector: COM2
The mainboard offers one 9-pin male DIN connector COM 1 (on the rear
panel), and one optional serial port JCOM1. Both are 16550A high speed
communication ports that send/receive 16 bytes FIFOs. You can attach a
serial mouse or other serial device directly to them.

Clear CMOS Jumper: JCLR1
There is a CMOS RAM on board that has a power supply from
external battery to keep the data of system configuration. With the
CMOS RAM, the system can automatically boot OS every time it
is turned on. If you want to clear the system configuration, use the
JCLR1 (Clear CMOS Jumper) to clear data. Follow the instructions in the image to clear the data.
MSI Reminds You...
You can clear CMOS by shorting 1-2 pin while the system is off. Then return to 2-3 pin position.
Avoid clearing the CMOS while the system is on, which will damage the mainboard.
PCI Express x16 Slot
The PCI Express slot, as a
high-bandwidth, low pin count, serial,
interconnect technology, support Intel
highest performance desktop platforms
utilizing the Intel Pentium 4 processor
with HT Technology with these platform
benefits. You can insert the expansion
cards to meet your needs. When adding
or removing expansion cards, make sure that you unplug the power supply first. PCI Express
architecture provides a high performance I/O infrastructure for Desktop Platforms with transfer
rates starting at 2.5 Giga transfers per second over a PCI Express x1 lane for Gigabit Ethernet,
TV Tuners, 1394 controllers, and general purpose I/O. Also, desktop platforms with PCI Express
Architecture will be designed to deliver highest performance in video, graphics, multimedia and
other sophisticated applications. Moreover, PCI Express architecture provides a high
performance graphics infrastructure for Desktop Platforms doubling the capability of existing
AGP8x designs with transfer rates of 4.0 GB/s over a PCI Express x16 lane for graphics
controllers, while PCI Express x1 supports transfer rate of 250 MB/s.
