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 Initalization Core Interface, where all referrences 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.
