This is done by hardware and BIOS, so there is no need
for DOS to take any effort with it :-) Also, SATA uses
low voltage differential signals, allowing indeed very
fast serial transmission of bits. All done in hardware.

And for SD cards in DOS, you typically have them in USB
readers, which are in turn supported by the BIOS, which
supports generic USB disk-like media such as USB sticks
and USB harddisks and cardreaders.

Cheers, Eric
