Urggg... Be careful! I don't know weather the driver is working on SMP
boards or not. I have a dual processor board here and I think version
0.7.0 will also support this, but the work on this version takes still

Yes, you have to edit itifgAM.c - lines 1382 to 1393.
MASTER: driveext = ENABLE, useext = DISABLE
SLAVE:  driveext = DISABLE, useext = ENABLE
Build two versions of the driver, one for the master and one for the
slave.
