Ah, the there is a catch in your statement.  Unless you have an
"appropriate" graphics adapter there is no "appropriate" value for
the attribute byte.  Seriously, this solution is not general.  The
fastest kludge is probably using the ansi.sys trick suggested by
several posters.  Else hercules text mode simulation (not always
available, mind you) by setting your appropriate attribute byte, or
back to the general graphics solution.
