Function Documentation

FatFindEltoritoPartitions()

BOOLEAN FatFindEltoritoPartitions	(	IN PEI_FAT_PRIVATE_DATA *	PrivateData,
		IN UINTN	ParentBlockDevNo
	)

This function finds Eltorito partitions. Main algorithm is ported from DXE partition driver.

Parameters

[in]	PrivateData	The global memory map
[in]	ParentBlockDevNo	The parent block device

Return values

TRUE	New partitions are detected and logical block devices are added to block device array
FALSE	No new partitions are added

Definition at line 27 of file Eltorito.c.

FatFindGptPartitions()

BOOLEAN FatFindGptPartitions	(	IN PEI_FAT_PRIVATE_DATA *	PrivateData,
		IN UINTN	ParentBlockDevNo
	)

This function is used for finding GPT partition on block device. As follow UEFI spec we should check protective MBR first and then try to check both primary/backup GPT structures.

Parameters

[in]	PrivateData	The global memory map
[in]	ParentBlockDevNo	The parent block device

Return values

TRUE	New partitions are detected and logical block devices are added to block device array
FALSE	No new partitions are added

Definition at line 486 of file Gpt.c.

FatFindMbrPartitions()

BOOLEAN FatFindMbrPartitions	(	IN PEI_FAT_PRIVATE_DATA *	PrivateData,
		IN UINTN	ParentBlockDevNo
	)

This function finds Mbr partitions. Main algorithm is ported from DXE partition driver.

Parameters

[in]	PrivateData	The global memory map
[in]	ParentBlockDevNo	The parent block device

Return values

TRUE	New partitions are detected and logical block devices are added to block device array
FALSE	No new partitions are added

Definition at line 102 of file Mbr.c.

FatFindPartitions()

VOID FatFindPartitions

(

IN PEI_FAT_PRIVATE_DATA *

PrivateData

)

This function finds partitions (logical devices) in physical block devices.

Parameters

PrivateData

Global memory map for accessing global variables.
