EFI_PEI_BLOCK_IO_MEDIA Struct Reference

Data Fields
EFI_PEI_BLOCK_DEVICE_TYPE	DeviceType
BOOLEAN	MediaPresent
UINTN	LastBlock
UINTN	BlockSize

Detailed Description

Specification inconsistency here: PEI_BLOCK_IO_MEDIA has been changed to EFI_PEI_BLOCK_IO_MEDIA. Inconsistency exists in UEFI Platform Initialization Specification 1.2 Volume 1: Pre-EFI Initialization Core Interface, where all references to this structure name are with the "EFI_" prefix, except for the definition which is without "EFI_". So the name of PEI_BLOCK_IO_MEDIA is taken as the exception, and EFI_PEI_BLOCK_IO_MEDIA is used to comply with most of the specification.
