These are similar to the Atari m68k suboptions. They are:
depth - specifies the pixel bit depth.
inverse - does the same thing as the Atari suboption.
font - does the same thing as the Atari suboption, although the
PEARL8x8 font is used instead of VGA8x8 font, if the display
size is less than 400 pixel wide.
monitorcap - specifies the capabilities of the multisync
monitor. Do not use with fixed sync monitors.
