PORTIBM PC Portable (uses same BIOS as XT) 0078 - Intel 82378IB ("Saturn"/"Neptune" chipsets) - BIOS(Basic Input/Output System) A set of standardized calls giving low-level access to the hardware.  The BIOS is the lowest software layer above the actual hardware and serves to insulate programs (and operating systems) which use it from the details of accessing the hardware directly. COUNT-DOWN TIMER
Notes:	the BIOS(Basic Input/Output System) A set of standardized calls giving low-level access to the hardware.  The BIOS is the lowest software layer above the actual hardware and serves to insulate programs (and operating systems) which use it from the details of accessing the hardware directly. uses this port for certain fine timings; presumably it is
	  independent of processor speed (it appears to decrement at 1 MHz)
	the address at which this port appears may be set via the 82378's
	  PCI configuration space word at offset 0080h (see #01064), or the
	  timer may be disabled entirely
