NAME
     lasi -- 2nd generation I/O subsystem

SYNOPSIS
     lasi*   at mainbus0
     lasi*   at phantomas?
     gsc*    at lasi?

DESCRIPTION
     Core bus controller and I/O subsystem as present on newer HP 9000/700
     workstations and single-board computers.  The supported core bus con-
     trollers are those used in conjunction with PA7100LC, PA7300LC and early
     PA8000 / PA8200 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)
