The DEC ether card that didn't work is placed in the slot shared with ISA, and today, I read, somewhere from AltaVista's output, that S1668 only supports bus mastering on 4 PCI slots out of 5 (I'm not sure whether this is true or not: Tyan's manual says nothing about this). Is this related to the problem? Nishio Shuichi
