After installing the NewerTech G3 upgrade card into the PowerMac 9500/180MP, I had some problems, when I tried to install Debian.
None of the sarge floppies would work and I eventually decided to get rid of any traces of MacOS and installed using the woody floppies. The problem is that the kernel 2.2.20 that comes with woody ins't able to see both PCI buses, especially the one where the video card is sitting on. I had to grab a kernel from testing's repository, but I don't like distribution kernels, for they are way too bloated.
Note to self: when replacing the
zImage on the HFS boot floppy, one
has to use the vmlinux image compressed with
gzip, like this:
gzip -9 vmlinux hmount /dev/fd0 hcopy vmlinux.gz :zImage humount /dev/fd0
No other image that I tried worked. But it was nice to (re)-discover how one makes a boot floppy for an OldWorld Mac.
