Not surprisingly, they turn out on examination to be yet another Donald
Becker creation:

http://www.scyld.com/diag/

The setup program is claimed to be able to set specific IRQ and I/O
assignments from the command line.  Which _seems_ to suggest disabling
of PnP mode, but that is untested by me.  (Note that Becker gives source
code and ultra-simple compilation instructions right on the Web page.)

All of the old 3C509b cards in my used-parts box had PnP disabled via
3Com's DOS utility and got set to IRQ10, I/O 300h, years ago.
