18 | <para os="a">You are nearly ready to boot to the new temporary system. |
---|
19 | One of the last things to do is to ensure that the system can be booted. |
---|
20 | The instructions below apply only to x86_64 machines on which lilo is going |
---|
21 | to be installed. Information on using a pre-installed Grub on machines |
---|
22 | currently running as x86 or x86_64 multilib should be available in the |
---|
23 | usual resource-specific locations for those architectures. If you have |
---|
24 | installed an x86 version of lilo, these instructions should be modified |
---|
25 | to refer to the <command>lilo</command> and <command>keytab-lilo.pl |
---|
26 | </command> commands you installed on the host system.</para> |

31 | |
---|
32 | <para os="c">If you have multiple systems on your machine using a different |
---|
33 | bootloader such as grub, you may prefer to use that instead - consult the |
---|
34 | appropriate documentation. The rest of this section assumes you are going |
---|
35 | to use lilo.</para> |
---|
36 | |
---|
37 | <para os="d">Earlier, we compiled and installed the Lilo boot loader software |
---|
38 | in preparation for this step. The procedure involves writing a boot image to |
---|
39 | a specific location on the hard drive. If you have a floppy disk drive, or |
---|
40 | if you have installed a cd recording program, we highly recommend using |
---|
41 | mkrescue to create a Lilo boot floppy, or CD (using e.g. dvdrecord from |
---|
42 | dvdrtools) as a test and as a backup.</para> |
---|
43 | |
---|
44 | <para os="e">Normally, you interact with lilo by using the cursor and enter |
---|
45 | keys to select from the available option(s), but sometimes it is necessary to |
---|
46 | add other boot options, such as e.g. 'init=/bin/bash' to debug boot failures. |
---|
47 | The more your keyboard layout differs from the US qwerty layout, the harder |
---|
48 | it will be to type boot options unless lilo knows about your keyboard layout. |
---|
49 | So, we will create a key table for Lilo (.ktl) file - at one point in the |
---|
50 | documentation these are referred to as .klt files, which may be a typo, but |
---|
51 | has been followed by some distros. The name, and location, are not important |
---|
52 | but it is conventional to put these in /boot with the name representing the |
---|
53 | key layout. For a British keyboard layout, the following command will |
---|
54 | achieve this:</para> |

58 | <para os="g">The argument to the command is the name of the keymap, or if |
---|
59 | necessary you can specify the full path to the keymap. Use whatever |
---|
60 | is appropriate for your keyboard.</para> |
