Re: midi problem, an isa device on a pci card

	Hello,
	I've recived no responses.  Anyway, the following includes my
own solution to the question, lots of trial and error.  I've found that
isahints was the closest exsting code to what I wanted. 
	As always, I would love to hear any comments.

	In pci device_attach:
isa=devclass_find("isa");
if( !isa ) {
	device_printf(sc->dev,"cmi midi error no devclass for isa\n");
	goto err;
}
if (devclass_get_devices(isa, &isalistp, &isacountp) != 0 ) {
	device_printf(sc->dev,"cmi midi error fetching isa devices\n");
	goto err;
}
if ( isacountp < 1 ) {
	device_printf(sc->dev,"cmi midi no isa busses found\n");
	goto err;
}
/*
 *      Be stupid and just pick the first isa bus
 */
sc->isadev = isalistp[0];
mpuisa=devclass_find("mpuisa");
if( !mpuisa ) {
	device_printf(sc->dev,"cmi: midi driver not found\n");
	goto err;
}
i = devclass_find_free_unit(mpuisa,0);
sc->mpudev = BUS_ADD_CHILD(sc->isadev, 1, "mpuisa", i);

	[Needs to be done with BUS_ADD_CHILD, I tried with others, m' yo
	they just don't work]

	[ Say, p->port=0x300, then following would set it to 0x300-0x302 
	  and the same IRQ as the pci device ]

bus_set_resource(sc->mpudev, SYS_RES_IOPORT, 0, p->port, 2);
bus_set_resource(sc->mpudev, SYS_RES_IRQ, 0, rman_get_start(sc->irq), 1);
if( device_probe_and_attach(sc->mpudev) == 0 ) {
	device_printf(sc->dev,"added %s/%s\n", 
		device_get_nameunit(sc->isadev), 
		device_get_nameunit(sc->mpudev) );
   return ;
}


	Cheers,
