Southbridge chipsets. It accommodates Intel Pentium 4 processors, which
supports a frontside bus (FSB) speeds up to 400/533 MHz.
The SiS645DX Northbridge features the AGTL & AGTL+ compliant bus driver
technology with integrated on-die termination to support Intel Pentium 4 series
processors with FSB 100/133 MHz. It can offer bandwidth up to 2.7 GB/s un-
der DDR333 and 1 GB/s under PC133 in order to sustain the bandwidth
demand from host processor, as well as the multi I/O masters and AGP mas-
ters.

IDE interfaces, a floppy controller, a high-speed serial port, a VGA port, an
EPP/ECP capable bi-directional parallel port connector, four USB (Universal
