The Debian Installation System ============================== Orientation This README is to acquaint you with the contents of the Debian installation system, and where to go for more information. If you wish to return to this directory you should go to <debian>/dists/woody/main/disks-ia64/current/ where the word `<debian>' may indicate a Debian web mirror, an FTP area, or official Debian CD-ROM. All the files required for installation can be found beneath this directory. Complete documentation for the Debian installation system is located within the `doc/' subdirectory. Documentation is available in several formats and languages. You may also wish to consult <URL:http://www.debian.org/releases/woody/> for errata, security alerts, and other updated information. For the impatient, quick install instructions are provided here. However, the reader is *strongly* encouraged to read the full documentation found in the `doc/' subdirectory, especially in the event of difficulties. Quick Installation Instructions =============================== Even though the Debian Installation System is also called the `boot-floppies', this name is something of an historical artifact. It is possible, even desirable, to install Debian without the use of floppies at all. For instance, you may be able to install Debian from an official Debian bootable CD-ROM, from the network, or from another operating system. CD-ROM Install ------------- The recommended installation method is the official Debian CD-ROM. These may be procured anywhere fine GNU/Linux distributions are sold, or online <URL:http://www.debian.org/distrib/vendors>. Those who have a CD burner and an adventurous disposition may try creating their own CD-ROM image <URL:http://cdimage.debian.org/>. Installation from CD-ROM is usually very easy and requires you to type only a single command after booting and CD insertion. If your machine has SRM (i.e. no menues system at the beginning) simply type `boot xxx -fl 0` where xxx is your CD-ROM drive in SRM notation. Run `show dev` to find out the name in your machine. For a complete description check out the installation manual. If your machine has ARC or AlphaBIOS, see below in the MILO section for details. Installation from Floppies -------------------------- If you either do not have a CD-ROM or you have a computer that cannot boot from a CD-ROM then you will have to use the floppy images located beneath this directory. Floppy images are named `*.bin'. You will generally need the `rescue.bin' and `root.bin' images, and often the `driver-*.bin' images as well. Note that there are various sets of these rescue, root, and driver images, depending on which architecture you are on. You will have to choose a set with which to install. See below for a detailed description of the various subdirectories which contain these floppy images. The `driver-*.bin' files contain extra hardware drivers not contained in the kernel in the `rescue.bin' image. It is not always required to create floppies from which to load these drivers, e.g., in cases where the installation is able to get the drivers from non-floppy media. It's basically a question of how much hardware support the kernel itself contains. If you do not create the `driver-*.bin' floppies, later during the installation you will need a copy `rescue.bin' and `drivers.tgz' to be available from non-floppy media. You will be prompted for the operating system and modules, and you cannot tell the system to use floppies, obviously, since you did not create the driver floppies. Direct the installer to get this data off the CD-ROM, local hard disk, or wherever the installation files were downloaded. You *cannot* create floppies from *.bin files by just copying the *.bin files over. You need to do a low-level sector copy of the data onto the floppy. The method you must use to create floppies from the *.bin files varies based on what operating system you have access to. Descriptions below cover creating floppies from *.bin files in Unix and from DOS. It is recommended that you always use fresh new floppies, because used ones can contain errors and cause failures in booting. - Creating Floppies from Floppy Images in Unix Use the GNU `dd' command to create a floppy disk from a .bin file: dd of=/dev/fd0 if=<file> bs=1024 Your floppy device may be something other than `/dev/fd0'. If you are naturally suspicious, you can make sure the image was successfully written: cmp /dev/fd0 <file> - Creating Floppies from Floppy Images in DOS Change directory (`cd') to the directory containing the *.bin files that you want. Use the DOS utility `rawrite2.exe' in the `dosutils' subdirectory to create the image, for instance: ..\dosutils\rawrite2 -f rescue.bin -d a where `a' refers to the first floppy drive on your computer, and `rescue.bin' represents the *.bin file from which you want to create a floppy. Layout Of The Installation Files ================================ The general organization of files in this directory is described below. If you are copying a subset of these files to local disk or what have you, you should retain the internal directory structure, since the installation system will be looking for files in these locations. doc/ The Debian GNU/Linux Installation Manual, the Beginner's Guide for `dselect', and the Release Notes may be found here in several computer readable and printable formats. Please, Read The Fine Manual (RTFM) before you begin! ** Specific Files of Interest Using the descriptions above, you need to select the directory containing the set of files which is appropriate to the installation you are doing. You will need all of the following `.bin' images, unless marked otherwise. .../rescue.bin Rescue disk image, containing the kernel and a boot loader. .../root.bin Root disk image, containing the root file system. Not required unless are you are installing from floppies. .../driver-#.bin Device driver disk images, containing kernel modules you can load for hardware for which there is not a driver built into the kernel. For instance, you can use this to install a driver for your network adapter; once you have installed that driver, you can install the rest of the system over the network. Other modules include PPP, parallel support, etc. Not required unless are you are installing from floppies. .../drivers.tgz A compressed tar archive containing the same modules as the above disk images. These are used when installation kernel and drivers from local disk or CD rather than from floppies. Use the file from the appropriate subdirectory based on the you are using, if any. md5sum.txt A file containing MD5 sums for installation files. This can be used to verify that downloaded files have not been corrupted.
