... Now I got some interesting news. I took Stephen Marenka's config for a 2.6.25.2 kernel and chopped out just enough to squeeze the kernel on a single floppy. And guess what? It actually booted! Well, sort of.
Nice!
The kernel messages started scrolling like normal then the whole machine spontaneously shut off. I seen this happen once before when I had the fpu emulation option turned on. So I turned it off and tried again. This time it didn't boot. It stopped at the same place as before.
I wonder if it is possible to build a kernel having no FPU emulation and containing no FPU instructions. CONFIG_M68KFPU_EMU_ONLY depends on CONFIG_M68KFPU_EMU...
I'll hope to be able to give more debugging information soon. I'll be setting up a serial cable shortly. By the way, do you know what the settings I need to set on the other mac to read the powerbook's serial port?
You get to choose those settings. The command line I gave has "9600n8" meaning 9600 baud, no parity, 8 data bits (and 1 stop bit). Which is probably the default anyway. BTW, this is purely for debugging. The driver for the userland /dev/ttyS0 device (e.g. for serial console login) is not available (though we could probably use the powermac zilog driver).
