HISTORY

     The esp driver first appeared in NetBSD 1.3.  The first FreeBSD version to include it was
     FreeBSD 5.3.

AUTHORS

     The esp driver was ported to FreeBSD by Scott Long ⟨scottl@FreeBSD.org⟩ and later on
     considerably improved by Marius Strobl ⟨marius@FreeBSD.org⟩.

BUGS

     The esp driver should read the EEPROM settings of Tekram controllers.
