Detailed timing descriptor (DTD) is an 18 byte array describing video
mode (screen resolution, display properties, etc.) in Intel Option
ROM. Option ROM can support multiple video modes, specific mode is
picked by the BIOS through the appropriate Option ROM callback
function.
The new utility allows to interpret the 18 byte hex DTD dump, and/or
modify certain values, and generate a new DTD.
To parse the DTD contents just pass the 18 bytes to the utility in the
command line. To modify the existing contents and generate a new dump
precede the 18 bytes with '-m' and follow prompts.
