Clear CMOS Jumper: JCMOS1
There is a CMOS RAM onboard 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, set the JCMOS1 (Clear CMOS Jumper ) to clear data.

MSI Reminds You...
To clear CMOS you should:
1. switch off the system and short 2-3 pin of the JCMOS1;
2. switch on the system again and the message “CMOS checksum
error” should appear;
3. switch off the system and return to 1-2 pin (Keep Data) position;
4. switch on again for operation.
Please avoid clearing CMOS while the system is on; it will damage
the mainboard.

PCI Slots
PCI Express Slots
The PCI Express slot, as a high-bandwidth, low pin count, serial, interconnect
technology, supports Intel highest performance desktop platforms utilizing the Intel
Pentium 4 processor with HT Technology.
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.
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 (Peripheral Component Interconnect) Slots
The PCI slots allow you to insert the expansion cards to meet your needs.
When adding or removing expansion cards, make sure that you unplug the power
supply first. Meanwhile, read the documentation for the expansion card to make any
necessary hardware or software settings for the expansion card, such as jumpers,
switches or BIOS configuration.
