EXFATFS_MASTER_BOOT_REC Struct Reference

Public Attributes
uint8_t	boot_code [390]
	Boot program.
uint8_t	bytes_per_sector
	Power of 2. Minimum 2^9 = 512 bytes, maximum 2^12 = 4096 bytes.
uint8_t	cluster_cnt [4]
	Number of clusters in the cluster heap.
uint8_t	cluster_heap_offset [4]
	Sector address of the data region.
uint8_t	drive_select
	Used by INT 13.
uint8_t	fat_len_in_sectors [4]
	Size of FAT in sectors.
uint8_t	fat_offset [4]
	Sector address of first FAT.
uint8_t	fs_name [8]
	"EXFAT "
uint8_t	fs_revision [2]
	VV.MM.
uint8_t	jump_to_boot_code [3]
	0xEB7690
uint8_t	must_be_zeros [53]
	Must be 0x00.
uint8_t	num_fats
	1 or 2 (only 2 if TexFAT is in use)
uint8_t	partition_offset [8]
	Sector address.
uint8_t	percent_of_cluster_heap_in_use
	Percentage of the heap in use.
uint8_t	reserved [7]
	Reserved.
uint8_t	root_dir_cluster [4]
	Cluster address of the root directory.
uint8_t	sectors_per_cluster
	Power of 2. Minimum 2^1 = 2. Maximum is dependant on the fact that the max cluster size is 32 MiB.
uint8_t	signature [2]
	0xAA55
uint8_t	vol_flags [2]
	Flags: ActiveFAT, Volume Dirty, Media Failure, Clear to Zero, and Reserved.
uint8_t	vol_len_in_sectors [8]
	Size of total volume in sectors.
uint8_t	vol_serial_no [4]
	Volume serial number.
