The boot floppy is ejected after the miboot run (the little icon
with the penguin) had finished and few more seconds (enough time for
the kernel to boot and display the usual "insert root disk" message)
have passed.  Floppy ejection at this point is normal and could also
mean that the kernel boots fine, only that the local console is

That is the second attempt was made on completely unrelated systems
(both the PC generating the floppy and the Mac were different).

Disk was made apparently without errors, and cmp showed no
differences. (I was more careful with that after your last mail

I will buy a cleaning set soon, but I would appreciate it if someone
could test the current images (Holger?) on similar hardware.
