Hi Finn, Actually, I have not tested the Debian kernel.
Right ... you mentioned that it doesn't fit on a floppy. For testing purposes, I generally download kernels with MacOS over ethernet and boot them with Penguin (though I guess floppies are more convenient sometimes). This is reasonably efficient, because MacOS has time to reboot while the next kernel is being built.
Both kernels are my own build; the only difference between them is that I set a boot_delay on the kernel command line which stops it from shutting down. If you'd like a copy of my config, let me know.
The kernel binary you sent to me works reasonably well on my PB190. If it escapes the scsi bug, it boots into the emile initrd. (See below for kernel messages.) It's a suprisingly functional initramfs -- given it is a mere 1,176,753 byte vmlinux.gz. (And from looking at the .config, the kernel could be made smaller too. I'll send you a better config.) Finn
Thanks, J Silverman
