This chapter describes features of the processor board used by the

6180 Industrial Computer.

The onboard I/O controller (National Semiconductor 306B)

integrates the functions for the serial ports, parallel port, diskette

drives, RTC and keyboard. This component provides:

• Multi-mode bi-directional parallel port

– Standard mode; IBM and Centronics compatible

– Enhanced Parallel Port (EPP) with BIOS/Driver support

– High-speed mode; Extended Capabilities Port (ECP)

compatible

• Integrated real time clock with an accuracy of  13 minutes/year

• Integrated 8042 compatible keyboard controller

• Industry standard diskette driver controller with 16 byte data

FIFO (2.88 MB floppy support)

• Support for IrDA-compliant (version 2.0) infrared interface. The

infrared interface supports data transfer rates of up to 115 Kbaud

with either half- or full-duplex operation. In full-duplex mode,

both the transmitter and receiver are enabled simultaneously for

faster throughput.

• A 242-byte battery backed CMOS RAM

• Two NS16C550-compatible UARTs with send/receive byte FIFO

The system BIOS provides ISA and PCI compatibility. The BIOS is

stored in Flash EEPROM on the processor board. The BIOS

provides the power-on self test (POST), the system Setup program,

the PCI and IDE configuration utility, the Windows 95 Plug and Play

and the BIOS recovery code.

The system BIOS supports shadowing, which allows the BIOS to be

executed from 64-bit onboard DRAM.
