Geert may know more details. Thanks Michael for the level headed on-topic reply, I appreciate it. That smc is used by 20-odd arm defconfigs, so it really isn't valid to consider it as a stand alone ISA card used just by older x86 hardware with ISA bus. In fact I'm not sure it ever shipped as a standalone ISA card... Paul. > > Cheers, > > Michael
