This check-in fixed the following bugs:

1.	Pci22.h EFI_LEGACY_EXPANSION_ROM_HEADER definition error
(MdePkg\Include\IndustryStandard\Pci22.h; Tools\CCode\Source\Include\IndustryStandard\Pci22.h)
2.	SetVariable() with DataSize=0xffffffff will cause system hang
(EdkModulePkg\Universal\Variable\RuntimeDxe\Variable.c)
3.	Windows XP Pro & XP HOME Fails to Install from Retail CD
(EdkModulePkg\Bus\Pci\Pcibus\Dxe\PciResourceSupport.c)
4.	Pci22.h header file needs to add some recent type
(MdePkg\Include\IndustryStandard\Pci22.h; Tools\CCode\Source\Include\IndustryStandard\Pci22.h)
5.	Fix issues when ODD cannot boot from Sil0680 PCI-IDE controller
(EdkModulePkg\Bus\Pci\PciBus\Dxe\PciOptionromSupport.c;
