Exactly. It was needed for seeing the second PCI bus of the oldworld, where the video card (an imstt card) currently sits. Otherwise, life with X was much harder. > Do you know which options you need for running the kernel on an > oldworld (minimal .config would be nice to have). I don't remeber exactly what I did, but I didn't make anything special (or, at least, I don't think so). I am currently installing woody on such powermac to see what are the exact options. I will report back with the .config file that I used. Oh, one thing to have in mind: the kernel tree that I used was always Ben's tree. I rarely use kernels from Debian proper. > Do you think it would be possible to make a minimal kernel (everything > not needed for booting into an initrd in modules) that works on > newworlds and oldworlds and fits on a floppy (compressed) at the same > time?

I think that it should be an easy task, since quik just installs (in theory) a boot block and it loads the kernel. Let's see what happens. I just have to find some free time to read the code and see how I could help. The worst problem that I had (and my main reason to using a boot floppy approach instead of using quik) was that whenever the kernel I compiled had some problems, I ended with a dead system, as I couldn't pass parameters to quik at boot time or switch to another kernel (since I couldn't see Open Firmware). Nasty, huh? :-( I made a log of some of my experiences trying to get this thing working at <http://www.ime.usp.br/~rbrito/diary/2001.html>.
