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 Glenn Dicus
