10
12 EXTLINUX is a new syslinux derivative, which boots from a Linux
13 ext2/ext3 filesystem. It works the same way as SYSLINUX, with a few
14 slight modifications. It is intended to simplify first-time installa‐
15 tion of Linux, and for creation of rescue and other special-purpose
16 boot disks.
17
18 The installer is designed to be run on a mounted directory. For exam‐
19 ple, if you have an ext2 or ext3 usb key mounted on /mnt, you can run
20 the following command:
21
22 extlinux --install /mnt
23
25 -H, --heads=#
26 Force the number of heads.
27
28 -i, --install
29 Install over the current bootsector.
30
31 -O, --clear-once
32 Clear the boot-once command.
33
34 -o, --once=command
35 Execute a command once upon boot.
36
37 -M, --menu-save=label
38 Set the label to select as default on the next boot
39
40 -r, --raid
41 Fall back to the next device on boot failure.
42
43 --reset-adv
44 Reset auxiliary data.
45
46 -S, --sectors=#
47 Force the number of sectors per track.
48
49 -U, --update
50 Updates a previous EXTLINUX installation.
51
52 -z, --zip
53 Force zipdrive geometry (-H 64 -S 32).
54
55 --device=devicename
56 Override the automatic detection of device names. This option
57 is intended for special environments only and should not be used
58 by normal users. Misuse of this option can cause disk corrup‐
59 tion and lost data.
60
62 The extlinux configuration file needs to be named syslinux.cfg or
63 extlinux.conf and needs to be stored in the extlinux installation
64 directory. For more information about the contents of extlinux.conf,
65 see syslinux(1) manpage, section files.
66
68 I would appreciate hearing of any problems you have with SYSLINUX. I
69 would also like to hear from you if you have successfully used SYS‐
70 LINUX, especially if you are using it for a distribution.
71
72 If you are reporting problems, please include all possible information
73 about your system and your BIOS; the vast majority of all problems
74 reported turn out to be BIOS or hardware bugs, and I need as much
75 information as possible in order to diagnose the problems.
76
77 There is a mailing list for discussion among SYSLINUX users and for
78 announcements of new and test versions. To join, send a message to
79 majordomo@linux.kernel.org with the line:
