* Revision 1.7 1994/02/23 04:39:49 briggs
* Bail out in the probe since it's not safe at the moment (hangs on my
* DaynaPort card). Will fix when I get docs for the card.
* Revision 1.8 1994/02/26 03:01:22 briggs
* Cleaned up the probe a little by actually using data from the decl. ROMs.
*
* Revision 1.6 1994/02/22 01:15:00 briggs
* Get rid of if_init assignment.
