Bugzilla List

Update Notes

• If the user has the windows bat script that calls Split in it，it needs to change to "call Split" because Split will be a bat script but not an executable file.
• Shell depends on library class OrderedCollectionLib. Platform DSC needs to configure it in [LibraryClasses]
  OrderedCollectionLib|MdePkg/Library/BaseOrderedCollectionRedBlackTreeLib/BaseOrderedCollectionRedBlackTreeLib.inf
• Some struct fields in SmBios.h have typos and get fixed in these code change 0db8, bd9d, e157. Details are listed below.
  In struct SMBIOS_TABLE_TYPE17:
   FirwareVersion ==> FirmwareVersion
  In struct SMBIOS_TABLE_TYPE4:
   ProcessorManufacture ==> ProcessorManufacturer
  In struct PROCESSOR_CHARACTERISTIC_FLAGS:
   Processor64BitCapble ==> Processor64BitCapable
 ProcessorEnhancedVirtulization ==> ProcessorEnhancedVirtualization
 Processor128bitCapble ==> Processor128BitCapable
  Platform code that uses those fields need modifications.
