%! Detailed register description file for PCICFG.EXE by Ralf Brown
%!
%! Filename 80867110.PCI = Vendor 8086h, Device 7110h
%! Intel 82731AB PIIX4 PCI-to-ISA Bridge
%! Last Edit 31 Dec 1997 by Andy Sawyer
%!
%! Reference : Intel document 29056201.PDF
%! "82371AB PCI-TO-ISA/IDE XCELERATOR (PIIX4)"
%!
%! Since the 82371AB indicates that it is a "single function" device
%! for all functions except function 0, version 1,0 of PCICFG.EXE
%! does not correctly display all functions.
