iv Chapter 1 Introducing the Mainboard Introduction Thank you choosing the K7SOM+ mainboard. This mainboard has a Socket462 processor socket for the AMD K7 type of processors. You can install any of these processors on this mainboard. This mainboard supports front-side bus speed of 266MHz. This mainboard integrates the SiS740 Northbridge and SiS962/962L Southbridge chipsets that support a DDR/SDRAM interface, Ultra DMA 33/66/100/133 function and remarkably high system performance under all types of system operations. This mainboard has a built-in AC97 Codec, providing an AMR (Audio Modem Riser) slot to support Audio and Modem application, and a built-in 10BaseT/100BaseTX Network Interface. This mainboard has the embedded 256-bit 3D AGP Graphics Accelerator with 64MB frame buffer, supporting AGP 4X 266MHz mode up to 2GB/s bandwidth, which provides a direct connection between the graphics sub-system and memory so that the graphics do not have to compete for processor time with other devices on the PCI bus. The mainboard supports built-in USB 2.0 providing higher bandwidth, implements Universal Serial Bus Specification Revision 2.0 and is compliant with UHCI 1.1 and EHCI 0.95. This mainboard also supports the optional built-in IEEE1394a function only when SiS962 SB is installed. There is a set of ATX I/O Ports including two PS/2 ports for keyboard and mouse, one parallel port, one serial port and one VGA port, one MIDI/Game port and maximum four USB 2.0 ports--two back-panel ports and onboard USB header making two extra USB ports by connecting the Extended USB Module to the mainboard. The board is Micro ATX size and has power connectors for an ATX power supply.
