This line is supposedly to be used in case the expansion board hardware detects an error. Dirty hack: the IOCHK line is the _last_ pad on the ISA connector, so the one closest to the metal mounting bracket. One side of the board/connector is ground, the other one is IOCHK. You could try some adhesive tape on the BT to see if the panic goes away.. So much for a hardware fix for (maybe) a sw problem ;-) Wilko _ ______________________________________________________________________ | / o / / _ Bulte email: wilko @ yedi.iaf.nl http://www.tcja.nl/~wilko |/|/ / / /( (_) Arnhem, The Netherlands - Do, or do not.
