This got me past the "unable to open console" problem so that I can use 
the CD to boot with the "root=/dev/sda3", but it still tells me that 
there is no bootable media unless I have the CD in.

I have tried "lilo -M /dev/sda mbr" "lilo -b /dev/sda" both of which 
tell me that the MBR has been updated,
