Get Surface (it's my graphics library with 8, 15, 16, and 24 bpp
support) from http://www.cs.utexas.edu/users/lonniem/src.zip.  Unzip
it and look in src/font.c.  In the function fontinit () the 8x8 bios
font is read from conventional memory using movedatal.  It shows how
to use _dos_ds and gives the correct offset.  In case you don't want
to do that...the offset from _dos_ds is 0xFFA6E.  Just read 8 x 256
bytes starting at that address.  Using movedatal and putting it in
your own address space is the easiest way to do this.
