Most FDISK-type programs don't believe in booting from an extended partition and refuse to activate it. LILO is accompanied by a simple program (
activate
) that doesn't have this restriction. Linux
fdisk
also supports activating extended partitions.
...partition.
LILO can be forced to put the boot sector on such a partition by using the
-b
option or the
boot
variable. However, only few programs that operate as master boot records support booting from a logical partition.
...BOOTLIN
A more recent program called
LOADLIN
uses the same approach. Those who wish to use this method of booting are advised to use
LOADLIN
instead of
BOOTLIN
.
...BOOTACTV
Other, possibly better known boot switchers, e.g.
OS/2 Bootmanager
operate in a similar way. The installation procedures typically vary.
...system(s).
And the author would like to be notified if booting the other operating system(s) doesn't work with LILO , but if it works with an other boot partition selector.
...BOOT.SYS.

...case.
If only ``unimportant'' parts of the system are located on the ``high'' drives, some functionality may be available.
...de-fragmentation.
Setting the ``system'' attribute from DOS on the critical files (e.g. everything in
C:27#27LINUX
) may help to protect them from being rearranged. However, the boot floppy should still be ready, just in case.
...image
The default boot image is either the first boot image, the image specified with the
default
variable, or the image that has been selected at the boot prompt.
...number
This is a list of device numbers of some frequently used devices:
53#53
...11/dev/hda3".
The device names are hard-coded in the kernel. Therefore, only the ``standard'' names are supported and some less common devices may not be recognized. In those cases, only numbers can be used.
...options.
Options are frequently repeated when a string defined with
append
or
literal
is prepended to the parameters typed in by the user. Also, LILO implicitly prepends the options
ramdisk
,
ro
,
root
, or
rw
when
ramdisk
,
read-only
,
read-write
, or
root
, respectively, are set in the configuration file. (
lock
and
vga
are handled by a different internal mechanism.)
...set.
E.g. if your root partition is mounted on
/mnt
, you can update the map by simply running
ROOT=/mnt /mnt/sbin/lilo
...erased.
-R
is typically used in reboot scripts, e.g.
#!/bin/sh
cd /
if /sbin/lilo -R "$*"; then
to 0pt
echo 93#93 shutdown -r now
fi
...sector.
The boot sector is loaded by LILO 's secondary boot loader before control is passed to the code of
chain.b
.
...Otherwise,
I.e. if the BIOS device code, the number of sectors, the number of heads and the partition start are specified. Note that the number of cylinders may appear to vary if
cylinders
is absent and only some of the partition starts are specified.
...directory.
E.g.
/usr/src/lilo
...disktab
Actually, it shouldn't, because
disktab
is now obsolete.
...-v
If you've already installed LILO on your system, you might not want to overwrite your old map file. Use the
-m
option to specify an alternate map file name.
...re-built.
It is advisable to keep a second, stable, kernel image that can be booted if you forget to update the map after a change to your usual kernel image.
...desired.
Backup copies of old boot sectors may be needed when removing the boot sector. They are stored in
/boot
.
...sections.
When using a
disktab
file, you don't have this restriction. The additional flexibility offered by this is, however, useless and dangerous.
...name.
Because different partition programs may display the partitions in a different order, it is possible that what you think is your first partition isn't
/dev/hda1
, etc. A good method to verify the content of a partition is to try to mount it.
...distribution.
The expected version number may be different from the version number of the LILO package, because file version numbers are only increased when the file formats change.
...active.
Future versions of LILO may be able to change the active flag dynamically.
