You can change the border color by using the BIOS call to change all the
palete registers at one time. However, the resulting border is so narrow
that it doesn't fill the screen. Also on my real IBM monitor it makes the
video drive circuits very unhappy, so that half of the screen changes shade.
An article in (probably) PC MAgazine claimed that you could reprogram the
video controller to get more overscan, and thus a real border, so long as
the resultant slower scan rate didn't melt your monitor (a la melted
monochrome monitors hooked to CGA cards!). Since I like black, I didn't
save it. Anyone remember exactly how this works?
