setvid is a resident program used to force the EGA into 4 color graphics
mode. it is activated by hitting the ALT key and the right hand SHIFT key
at the same time.
A good example of where to use setvid is in the public domain game striker.
when striker switches to graphics mode it accesses the video registers
directly, since the EGA is not totally compatable with the old CGA you get
garbage. to solve this problem you would run setvid then striker,
then when the screen gets messed up you would hit ALT-right SHIFT
