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:

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