MSI Reminds You...
You can clear CMOS by shorting 2-3 pin while the system is off. Then return to 1-2 pin position. Avoid
clearing the CMOS while the system is on; it will damage the mainboard.
AGP (Accelerated Graphics Port) Slot (for 845GEM-V only)
The AGP slot allows you to insert the AGP graphics card. AGP is an interface specification designed for
the throughput demands of 3D graphics. It introduces a 66MHz, 32-bit channel for the graphics
controller to directly access main memory. The mainboard supports 4x/8x 1.5V AGP card.
