I do have these lines in the global options of my lilo.conf though:

This reminded me of another unsolved puzzle on my machine.

In my lilo.conf there is the following stanza:

other=/dev/hde1
        label=windowsOriginal
        table=/dev/hde
        map-drive=0x80 to=0x81
        map-drive=0x81 to=0x80

I don't know how these last two lines got there. The windows stanza doesn't boot, but that may be because I mistakenly broke the chain of fat partitions. I have restored them, but I probably need to re-install windows, I guess. But that's a different issue.

The point here is that those two lines appear to contradict each other. Is there a point to this? If so, what's happening?

I think two sections from 'info lilo.conf' would be germane:


disk=<device-name>
       Defines  non-standard  parameters  for  the specified disk.  See
       section "Disk geometry" of  user.tex  for  details.   Especially
       useful  is  the  `bios=' parameter.  The BIOS numbers your disks
       0x80, 0x81, etc. and it is impossible to decide which Linux disk
       corresponds  to  which BIOS disk (since this depends on the BIOS
       setup, and on the type of BIOS), so if you have an unusual setup
       you  need  to  state  the correspondence between Linux disks and
       BIOS disks.  For example,

                     disk=/dev/sda
                          bios=0x80
                     disk=/dev/hda
                          bios=0x81

        would say that your SCSI disk is the first BIOS disk,  and  your
       (primary master) IDE disk is the second BIOS disk.


[...]



map-drive=<num> Maps BIOS calls for the specified drive to the device code spec- ified on the next line as to=<num>. This mapping is useful for booting operating systems, such as DOS, from the second hard drive. The following, swaps the C: and D: drives,

                 map-drive=0x80
                    to=0x81
                 map-drive=0x81
                    to=0x80

Seems relevant. Maybe there is some correlation to your situation(s). hth.
