compaq Prosignia 800 boots up after Linux Redhat 6.1 install with LI in upper left corner of screen.
See bug #7648. Probably it is the same problem, i.e. the option "linear" in the lilo.conf would solve it. I have helped myself booting with 6.0 bootable floppy, but you may not have it at hand. RedHat MUST provide recipe to correct the lilo.conf with kind of recovery floppy, or other bootable media.
