PORTIBM PC Portable (uses same BIOS as XT) 0026-0027 - Chips&Technologies CS4021 - "SuperState V" ALTERNATE CONFIG
Desc:	alternate copy of the configuration register access at PORTIBM PC Portable (uses same BIOS as XT) 0022h/0023h
	  which may be used by system software in "SuperState V" to configure
	  the chipset without disturbing accesses to PORTIBM PC Portable (uses same BIOS as XT) 0022h by user code
Notes:	SuperState V is an early version of system management mode
	these ports can only be accessed while the system is in SuperState V;
	  similarly, some configuration registers are read-only via PORTIBM PC Portable (uses same BIOS as XT) 0022h
	  and others can optionally be made read-only
