If you have PnP stuff, the isapnp toolsuite might be helpful.
Use pnpdump for probing for PnP devices - ti spits out all their
data to stdout in a form you can directly use as a conf file for
the PnP setting tool, isapnp with some editing to put in the
values you want. When everything works, just put it into your
startup scripts in a place prior to activating the respective

I just used it to get a PnP networking card going in a non PnP
BIOS computer. In a PnP BIOS computer you can use those tools to
override the BIOS set parameters to select values to your liking
( and that is a PLUS ! ).

might help people to get along with PnP paralell ports better.
