First a couple of references: You might find the LILO Mini HOWTO
and the LILO User's Guide
useful. While the Mini HOWTO appears up-to-date, unfortunately, the User's Guide is from 1997. Perhaps you can find a more recent one. You might have one on your system under /usr/share/doc
or be able to download a documentation package for it.
I linked to has a section of fatal "Map Installer" errors, but does not list yours. But let me make a stab at it (of course, I could be wrong!). The Map
is a file that LILO creates that tells it where to locate all of the files it will need at boot time. You said that you have some kind of an (unspecified) error with an initrd
line. Perhaps this problem is preventing LILO from locating the initrd
file and it therefore generates the fatal error. Is there some reason you can't just correct the error on the line? Do you not know what the error is? Does perhaps the specified file not exist?
If this continues to be a problem for you, perhaps you should consider using GRUB instead of LILO.
