In this section, vvv is used in package names in place of the version, to avoid referring here to specific versions. When retrieving a package, always get the latest version unless you have good reasons for not doing so.
These are sources for distribution bootdisks. Please use one of the mirror sites to reduce the load on these machines.
In addition to the distribution bootdisks, the following rescue disk images are available.
tomsrtbt, by Tom Oehser, is a single-disk boot/root disk
based on kernel 2.0.33, with a large list of features and support
programs. It supports IDE, SCSI, tape, network adaptors, PCMCIA and
more. About 100 utility programs and tools are included for fixing
and restoring disks. The package also includes scripts for
disassembling and reconstructing the images so that new material can
be added if necessary.http://www.toms.net/~toehser/rb/tomsrtbt-current.tar.gz

rescue02, by John Comyns, is a rescue disk based on kernel
1.3.84, with support for IDE and Adaptec 1542 and NCR53C7,8xx. It
uses ELF binaries but it has enough commands so that it can be used on
any system. There are modules that can be loaded after booting for
all other SCSI cards. It probably won't work on systems with 4 mb of
ram since it uses a 3 mb ram disk.http://sunsite.unc.edu/pub/Linux/system/recovery/rescue02.zip
resque_disk-2.0.22, by Sergei Viznyuk, is a
full-featured boot/root disk based on kernel 2.0.22 with built-in
support for IDE, many difference SCSI controllers, and ELF/AOUT. Also
includes many modules and useful utilities for repairing and restoring
a hard disk.http://sunsite.unc.edu/pub/Linux/system/recovery/resque_disk-vvv.tar.gz
cramdisk images, based on the 2.0.23 kernel, available for
4 meg and 8 meg machines. They include math emulation and networking
(PPP and dialin script, NE2000, 3C509), or support for the parallel
port ZIP drive. These diskette images will boot on a 386 with 4MB RAM.
MSDOS support is included so you can download from the net to a DOS
partition.http://sunsite.unc.edu/pub/Linux/system/recovery/images/
Several packages for creating rescue disks are available on sunsite.unc.edu. With these packages you generally specify a set of files for inclusion and the software automates (to varying degrees) the creation of a bootdisk. See http://sunsite.unc.edu/pub/Linux/system/recovery/!INDEX.html for more information. Check the file dates carefully --- some of these packages have not been updated in several years and will not support the creation of a compressed root filesystem loaded into ramdisk. To the best of our knowledge, Yard is the only package that will.
Graham Chapman has written a set of scripts that may be useful as examples of how to create bootdisks. In previous versions of this HOWTO the scripts appeared in an appendix, but they have been deleted from the documented and placed on a web page:
http://www.zeta.org.au/~grahamc/linux.html
You may find it convenient to use these scripts, but if so, read the instructions carefully --- for example, if you specify the wrong swap device, you will find your root filesystem has been throroughly and permanently erased. Be sure you have it correctly configured before you use it!
Written by Werner Almesberger. Excellent boot loader, and the documentation includes information on the boot sector contents and the early stages of the boot process.
Ftp from ftp://tsx-11.mit.edu/pub/linux/packages/lilo/lilo.vvv.tar.gz. It is also available on Sunsite and mirrors.
These are available from many sources. Look at the usenet newsgroups
news.answers and comp.os.linux.announce.
The FAQ is available from http://sunsite.unc.edu/pub/Linux/docs/faqs/linux-faq and the HOWTOs from http://sunsite.unc.edu/pub/Linux/docs/HOWTO.
Most documentation for Linux may be found at The Linux Documentation Project homepage.

An excellent description of the how the new ramdisk code works may be found with the documentation supplied with the Linux kernel. See /usr/src/linux/Documentation/ramdisk.txt. It is written by Paul Gortmaker and includes a section on creating a compressed ramdisk.
For more detail on the Linux boot process, here are some pointers:
Contain assembly code for the bootsector.
Contains code for uncompressing the kernel.
Directory containing kernel initialization code. setup.c contains the
ramdisk word.
Contains the ramdisk driver. The procedures rd_load and
rd_load_image load blocks from a device into a ramdisk.
The procedure identify_ramdisk_image determines what
kind of filesystem is found and whether it is compressed.
