Chapter 1 System Board
The system board is a dual-processor system board built on an ATX
baseboard that supports the Intel Pentium II CPU processor running
at 266/66 MHz, 300/66 MHz, 333/66 MHz, 350/100 MHz, 400/100
MHz, and future Intel Pentium II processors. It contains an exclusive
connector for the CPU board that carries two slots for the Pentium II
CPU modules.
The host bus interface supports a Pentium II processor with 66 or 100
MHz bus frequency. It also supports synchronous DRAM (SDRAM)
DIMMs.
The system board supports PCI IDE, universal serial bus (USB)
host/hub, and enhanced power management. It also supports Ultra
DMA/33 synchronous DMA-compatible devices.
A 50-pin Fast SCSI (Small Computer System Interface) and a 68-pin
Wide SCSI comes with the system board to connect SCSI devices.
Wide SCSI supports 16-bit transfers while fast SCSI uses a 8-bit bus
that doubles the clock rate to support data rates of 20 Mb/s.
The system board also supports the USB (Universal Serial Bus)
connector, and other standard features such as two UART NS16C550
serial ports, one parallel port with Enhanced Parallel Port
(EPP)/Extended Capabilities Port (ECP) features, a diskette drive
interface, and two embedded hard disk interfaces. The board also
includes a built-in 10/100 Mb/s Intel 82557 LAN chip.
