DESCRIPTION
     The supported Core bus controllers are those used in conjunction with
     PA7100LC and PA7300LC CPUs and based upon LSI's macrochip that includes:

     o   Core bus controller
     o   System Clock
     o   Interrupt Controller
     o   Real Time Clock Interface
     o   Power System support
     o   RAM and Flash EEPROM controllers
     o   Two PS/2 ports
     o   RS-232 and Centronics I/O ports
     o   i82596CA LAN coprocessor
     o   NCR53c710 SCSI I/O processor
     o   Serial Interface for the CS4216 Audio Codec
     o   Interface for the WD37C65C floppy drive controller
     o   Optional Telephone interface (two fax/voice modem channels)
