If you dump this file to a floppy (e.g., gzcat filename >/dev/fd0) you
should be able to boot from it via the command:
boot dva0 -fi vmlinux.gz -fl "single root=/dev/fd0 ramdisk=1440"
The vmlinux.gz on this system is a minimal kernel that has no
networking support (SCSI and floppy etc. are in there, though). Also,
CONFIG_SERIAL_ECHO is enabled, so you might want to connect a terminal
at 9600 bps to /dev/cua1 to watch what's going on.
I'd be interested in hearing about success/failures with this image.
