They should be mapped into PCI address space with the rest, you should note though that a bunch of people have asked this a bunch of times and the response is usually null. If you want to output debugging info, try a serial port, or if you're still at the point in boot where the OF is still around, you can still output to it (check prom_init.c) and if not, the open firmware framebuffer console driver is your best friend.. sumedh tirodkar wrote:

I just found out that openfirmware boots into graphics mode(non-text mode). Now i wish to switch back to text mode. how do i do this?Unfortunately unless you are running some kind of yaboot-accessible or firmware-accessible x86 BIOS emulation, this isn't possible. -- Matt
