Maybe it is in an ifdef in EPICS. Still not sure why it would include that file though. It doesn't appear to be anywhere except libbsd. So the beatnik works with the new stack. That's good news. Do you happen to know about the mvme3100 or any of the motorola_powerpc boards? It looks like the drivers are in libbsd but I don't think anyone has reported them working. --joel > Gruss Heinz > > > > > On 11.
