I tested also
vmlinuz-2.6.15-1-mac<http://people.debian.org/%7Esmarenka/d-i/images-m68k/daily/kernels/vmlinuz-2.6.15-1-mac>15-Feb-2006 21:40 1.1M and "root=/dev/ram ramdisk_size=13000" with the same result on a SE/30.
It is needed - maybe - other cammand line for 2.6.15 kernels ?offtopic /Here - vmlinuz-2.2.25-mac- I'm stoped by the need of installer iso image, who is searched on disk. Is this from sarge or woody ?
