I have a couple of questions concerning programming VGA graphics.

1) Is there a BIOS service routine that will clear the screen?  What I
   do now is reset the video mode and restore the color table, but it is
   a little slow.  Is there a faster way to do this?

2) What's the routine number to go into 640x480 with 256 colors?  The book
   on VGA programming I have only gives the routine for 320x200x256.  I
   know my card will do 640x480x256, but I don't know how to tell it to
   go into that mode.

Please send answers to ccastgw@prism.gatech.edu.  I will summarize if there
is enough interest.
