Ultra1: On this one, I got (modulo any typos)
Loading initial ramdisk (1477684 bytes at 0x01x phys 022340800 virt) ...
[spinning \/]
Remapping the kernel ... FP Disabled
ok
and I was back to the OpenBoot 'ok' prompt.
This is strange.
Ultra10: On this one, I got much further. The kernel was loading,
but failed near the end. The last messages were
RAMDISK: couldn't find valid ramdisk image starting at 0.
Freeing initrd memory 1443k freed
cramfs: wrong magic
sh-2021: reiserfs_read_super: can not find reiserfs on ramdisk (1,0)
Kernel panic: VFS: Unable to mount root fs on 00:00
I hope this means something to somebody.
This means something. Atleast we are showing a ramdisk, but the start
point is all wrong. Did the old cd images work for you?
