Thanks for the hint.  i ran the following command:

sudo ~/linux-2.6.25/linux devfs=nomount load_ramdisk=1
ramdisk_size=30000 mem=128m initrd=initrd.gz root=/dev/ram0
ubd0=root_fs ubd1=/home/david/debian-40r3-i386-netinst.iso ubd2=/cdrom

It crashed.  See:

I created root_fs with the following commands:

dd if=/dev/zero of=root_fs bs=10M count=60
mkfs.ext3 ./root_fs

What am i doing wrong?
