Looking over the sourc code for outb I have noticed that there are several
definitions for outb, all of which are hard to understand.  In pcic_probe
there are two successive outb() calls to the same configuration port

outb(sp->index, 0x0E);
outb(sp>index, 0x37);

Then 

setb(sp, 0x3A, 0x40);

Does anyone know what this code is doing to the registers?  If so, which
definition of outb(), setb() are being implemented?  I am using FreeBSD
2.2.2-RELEASE.

Thanks
