Member Data Documentation

unsigned SDMINFAT::partitionTable::beginCylinderHigh

High bits cylinder for first block in partition.

uint8_t SDMINFAT::partitionTable::beginCylinderLow

Combine beginCylinderLow with beginCylinderHigh. Legal values are 0-1023. Only used in old PC BIOS.

uint8_t SDMINFAT::partitionTable::beginHead

Head part of Cylinder-head-sector address of the first block in the partition. Legal values are 0-255. Only used in old PC BIOS.

unsigned SDMINFAT::partitionTable::beginSector

Sector part of Cylinder-head-sector address of the first block in the partition. Legal values are 1-63. Only used in old PC BIOS.

uint8_t SDMINFAT::partitionTable::boot

Boot Indicator . Indicates whether the volume is the active partition. Legal values include: 0X00. Do not use for booting. 0X80 Active partition.

unsigned SDMINFAT::partitionTable::endCylinderHigh

High bits of end cylinder

uint8_t SDMINFAT::partitionTable::endCylinderLow

Combine endCylinderLow with endCylinderHigh. Legal values are 0-1023. Only used in old PC BIOS.

uint8_t SDMINFAT::partitionTable::endHead

head part of cylinder-head-sector address of the last sector in the partition. Legal values are 0-255. Only used in old PC BIOS.

unsigned SDMINFAT::partitionTable::endSector

Sector part of cylinder-head-sector address of the last sector in the partition. Legal values are 1-63. Only used in old PC BIOS.

uint32_t SDMINFAT::partitionTable::firstSector

Logical block address of the first block in the partition.

uint32_t SDMINFAT::partitionTable::totalSectors

Length of the partition, in blocks.

uint8_t SDMINFAT::partitionTable::type

Partition type. See defines that begin with PART_TYPE_ for some Microsoft partition types.
