The kernel cannot mount your root filesystem. I can think of two
possible reasons for this:
1. The kernel is configured to mount the wrong block device. I don't
know what 16:07 is, but you can change it in /etc/lilo.conf or,
like the message suggests, add a root=/dev/whatever at the lilo
prompt.
2. The device is correct but unusable. Did you remember to compile
IDE/SCSI, ext2/reiserfs and ELF support into the kernel? A module
won't help; the kernel needs to access the filesystem before it can
load any modules.
