Table 84 Read Multiple Command (C4h)

The Read Multiple command reads one or more sectors of data from disk media, then transfers the data from the device to the host.

The sectors are transferred through the Data Register 16 bits at a time. Command execution is identical to the Read Sectors command except that an interrupt is generated for each block (as defined by the Set Multiple command) instead of for each sector.

Output Parameters To The Device

Sector Count	The number of continuous sectors to be transferred. If zero is specified, then 256 sectors
	will be transferred.
LBA Low	The sector number of the first sector to be transferred. (L=0)
	In LBA mode, this register contains LBA bits 0 - 7. (L=1)
LBA High/Mid	The cylinder number of the first sector to be transferred. (L=0)
	In LBA mode, this register contains LBA bits 8 - 15 (Mid), 16 - 23 (High). (L=1)
H	The head number of the first sector to be transferred. (L=0)
	In LBA mode, this register contains LBA bits 24 - 27. (L=1)
Input Paramete rs From The Device
Sector Count	The number of requested sectors not transferred. This will be zero, unless an
	unrecoverable error occurs.
LBA Low	The sector number of the last transferred sector. (L=0)
	In LBA mode, this register contains current LBA bits 0 - 7. (L=1)
LBA High/Mid	The cylinder number of the last transferred sector. (L=0)
	In LBA mode, this register contains current LBA bits 8-15 (Mid), 16 -23 (High). (L=1)
H	The head number of the last transferred sector. (L=0)
	LBA mode, this register cont ains current LBA bits 24 - 27. (L=1)
