Poking around with the configuration program of our ethernet cards (NE2000 clones manufactured by Trust), I found out that they have a mode (called NE2000 plus) in which they apparently use shared memory (at least, the setup menu asks you to select a memory address. Is this mode supported by the current if_ed driver, and is it documented anywhere ? (I am asking because I remember discussion on the relative performance of WD80x3 -- better, using shared memory -- and NE2000 -- slower, with programmed IO) Thanks Luigi ==================================================================== Luigi Rizzo Dip. di Ingegneria dell'Informazione email: luigi@iet.unipi.it Universita' di Pisa tel: +39-50-568533 via Diotisalvi 2, 56126 PISA (Italy) fax: +39-50-568522 ====================================================================
