InstallCheck: after a hardware reset, the first read of the index port returns
	  88h, and a second consecutive read always returns 00h (while
	  read-after-write always returns the written value)
Range:	PORTIBM PC Portable (uses same BIOS as XT) 002Eh, PORTIBM PC Portable (uses same BIOS as XT) 015Ch, PORTIBM PC Portable (uses same BIOS as XT) 026Eh, or PORTIBM PC Portable (uses same BIOS as XT) 0398h, depending on
	  external strapping
Note:	to set a register, the data port must be written twice in a row; the
	  value is latched on the second write
