Module Name:\r
\r
  SimpleFileSystem.h\r
\r
Abstract:\r
\r
  SimpleFileSystem protocol as defined in the EFI 1.0 specification.\r
\r
  The SimpleFileSystem protocol is the programatic access to the FAT (12,16,32) \r
  file system specified in EFI 1.0. It can also be used to abstract a file  \r
  system other than FAT.\r
\r
  EFI 1.0 can boot from any valid EFI image contained in a SimpleFileSystem\r
