Red Hat Bugzilla – Bug 24286
The RH 7.0 version of LILO is broken for serial consoles
Last modified: 2007-04-18 12:30:46 EDT
The LILO that ships with RedHat 7.0 does not work correctly on a serial
console. LILO prints:
but does not permit you to select a kernel image. Upgrading to a recent
version of lilo (lilo-21.6 seems to work fine) solves the problem.
John Coffman, the current maintainer of LILO, had the following to say
about the problem:

This is a known bug. If you comment out message= (the graphical menu), the selection should
I'm going to re-assign this to msw. It seems to me that since the answer is not
to use the VGA message screen on a serial console machine, then there should
possibly be an option in the installer that allows us to disable the generation
of the VGA message in the lilo.conf file during install. Matt?
An another solution might be to hack lilo so that if you append parameters such that
serial console would be enabled, or give serial= setting, message= would automatically
We can have the installer not put message= when it knows that you're on serial
install. I think I'd like to get on mainline LILO, though.
Many people (including us, for example) install from standard console but put
secondary/primary console settings in afterwards.
I agree diverging will not be pretty in the long run. Lilo requires great deal of attention.
Getting rid of message= when the install is on a serial console is a quick,
easy hack to solve this problem for hard core serial console users, where
serial console may be the only method of access after a remote install (we
frequently install RedHat via two-kernel monte on remote systems, doing a full
install without even a redhat CD or a floppy).
The real solution, as others have noted, is merging back to the mainline LILO
and getting all of the other benefits that that provides (LBA support etc).
lba support is in the lilo we have already, and the menuing code is much much
different in mainline.

anaconda does the right thing for this case now
