Identification
Files begin with 'P' 'K' 0x08 0x08 -- this is shared with the CHR font files used by BGI. The four-byte signature is followed by either 'BGI Device Driver' or 'SVGA 256 Colour BGI Device Driver'.
Main Entry
The first 160 bytes of the driver file are a header. This is followed by the driver code segment. Far calls will be made to this address with SI containing the function number to execute.
