lilo 23.2: Fatal: trying to map files from unnamed device 0x001


Hi: I have browsed the web for that message but could not find anything useful for my case. Having got this message I reduced lilo.conf to a minimum:
Code:
$ cat /etc/lilo.conf
lba32
boot=/dev/sda
$
And I still got the same message. The machine has only one hard disk with three primary partitions and one extended partition, the hard disk being parallel ATA (IDE). I first used lilo 22.8 but got, with a complete lilo.conf, "Fatal: Setup length exceeds 31 muximum; kernel setup will overwrite boot loader". Then I saw a post where the author of lilo said he had taken notice of that message and that the poster would have to wait until lilo 23.2 was out, which prompted me to run 23.2, only to get the message in this post title. What can possibly be the cause?

I really know nothing about Lilo. Need to state that right off the bat.

I like bootloaders though and so this interested me enough to do a casual search. Have you looked at the wikipedia article. Looks like it was well written and has what looks like a good example of a /etc/lilo.conf file.

Also has quite a bit more information on usage and error codes.

More importantly some good looking external links.

What fs are you using? I found a reference to that message when used with btrfs, ext4 fixed it (also seemed to be related to the particular motherboard).

**UPDATE ** - I wrote the above assuming that it had been working and now failed for some reason, although now I see that is not actually stated in your original post.

So for my own clarity could you be explicit about the partitions and post a more complete lilo.conf, and let us know if it is a new install or one that previously worked.

That message is normally associated with the "root" specification line within a stanza (not the "boot" device line).

You must specify the kernel image to boot and the root device (passed to kernel).

Yes, the config file is far too minimal...

Have a read: https://wiki.debian.org/LILO

I have made many tests under different OSs and different versions of lilo. So the following can be a bit confusing.

This seems to be a known problem to the developers of lilo. The solution, go on to lilo 23.2. All this happened in the task of writting the MBR (aka boot sector) after having installed Debian 7.4. Debian 7.4 spoke of lilo and grub as in an equal foot. That is I could use one or the other. But in the process of installation, it offered me only grub. I said no. But then I saw there was no lilo in the whole bunch of software that had been downloaded from the net (netinst installation). So I booted with the Slackware 14.0 disk (as if installing for the first time), which has lilo 23.2 and invoked lilo. But lilo was not! So I went, in the DVD, to /slackware/a/ and 'installpkg lilo-.......xz'. Having run it, I got the message in this thread title.

Below is working lilo.conf as an example for booting current and backup kernel.
Code:
$ cat /etc/lilo.conf
disk = /dev/sda
        bios = 0x80
prompt
timeout = 30
default = gentoo

image = /boot/bzImage
        label = gentoo
        read-only
        root = /dev/sda1
        vga = 0x317
image = /boot/bzImage.pre
        label = gentoo.pre
        read-only
        root = /dev/sda1
