DOS device drivers (often simply known as SYS files) are stored in a simple binary format.
Drivers are loaded into a contiguous block of memory; the segment part of data structure pointers is then adjusted to match the loading segment.
Some device drivers are stored in the MZ format instead of the "raw" SYS format.
