Info: This provides a means to locate ROM-defined character-definition
tables.
A typical use would be to copy the table data, make some custom
modifications, then modify the EGA/VGA Data Areas to point to you
changed table, and then use TSR function to make the changes
permanent.
The tables are always CX*256 bytes long.
