Thanks for the info, I've done my best to follow it but I still must be doing something wrong: I've put in 3.1 ROMs, connected the OVR, INT2 and GND wires to the relevant pins on the expansion header, I have a 40-44pin IDE cable connected to a 44-pin CF adapter (CF adapter and card have been tested to work in other machines) but still nothing. Am I using the wrong kind of IDE cable? Is there a 40-pin CF adapter available somewhere? I have a 39-pin IDE cable but, of course, that won't work because it has 1 pin blocked, 40-pin ribbon cables seem to be hard to find. It's a rev6 board that I have modded for 1meg chip, could that be it? Any advice? Thanks!
