READ DMA (C8h)
Read data from sectors during Ultra DMA and Multiword DMA transfer. Use the SET FEATURES command to specify
the mode value. A sector count of zero requests 256 sectors.
READ MULTIPLE (C4h)
This command performs similarly to the Read Sectors command. Interrupts are not generated on each sector, but on
the transfer of a block which contains the number of sectors defined by a Set Multiple command.
