INSTALL NOTES FOR LINUX v0.97
|
|
Jim Winstead Jr. - 4 August 1992
|
|
|
|
This file contains basic instructions for installing Linux v0.97.
|
|
More detailed instructions have been written by others. Read the
|
|
Linux FAQ for some suggestions, and for pointers to other installation
|
|
documents.
|
|
|
|
COPYRIGHT
|
|
|
|
Linux 0.97 is NOT public domain software, but is copyrighted by Linus
|
|
Torvalds (torvalds@cc.helsinki.fi). The copyright terms follow the
|
|
GNU Copyleft. See the file COPYING from any GNU software package for
|
|
the finer points. Note that the unistd library functions and all
|
|
library functions written by Linus Torvalds are exempt from this
|
|
copyright, and you may use them as you wish.
|
|
|
|
WARNING
|
|
|
|
The 0.97 root disk requires the 0.96b or later kernel, although
|
|
the 0.97 kernel is strongly recommended. A bootable image of this
|
|
kernel should be available where you got the image for the 0.97
|
|
root disk.
|
|
|
|
INSTALLATION
|
|
|
|
1) First, and absolutely the most important step, MAKE BACKUPS OF YOUR
|
|
SYSTEM! This system won't do anything nearly as nasty as coredump all
|
|
over your harddrive (see 386BSD v0.0), but it is quite easy to
|
|
accidently screw something up while installing.
|
|
|
|
2) Test out the Linux v0.97 boot disk with the Linux v0.97 root
|
|
disk. If you are unable to get the boot disk to work properly on
|
|
your system, try posting to comp.os.linux, or contacting Linus.
|
|
|
|
Notice that Linux (as of v0.95) contains an init/getty/login suite,
|
|
and this will start up 'login' on the first four virtual consoles,
|
|
accessed by Left-Alt-F[1234]. If you experience problems on one
|
|
virtual console, it should be possible to switch to another one.
|
|
|
|
3) login as 'install', and the system will walk you through the
|
|
process of installing Linux on a hard drive partition. The
|
|
process is fairly automated, but the process requires that you go
|
|
through the steps of creating a partition for Linux usage. Some
|
|
tips follow:
|
|
|
|
Read the efdisk file from the intro login, which will explain
|
|
the basic concepts of hard disk partitions, and how to use
|
|
efdisk.
|
|
|
|
You may find it useful to login to one virtual console as
|
|
intro, so you can access the on-disk documentation, and
|
|
another as install, so you can do the installation and easy
|
|
access the documentation.
|
|
|
|
The maximum size of a Minix filesystem (the type created by
|
|
mkfs) is 64 megabytes. This is not a limitation of mkfs or
|
|
Linux, but a limitation of the Minix filesystem that is used.
|
|
|
|
With the release of Linux v0.97, a new 'extended' filesystem
|
|
has been released that supports 4 terabyte (!) partitions,
|
|
and extended filenames. The root disk does not contain
|
|
utilities to use this extended filesystem, however, because
|
|
the filesystem is still consider alpha code.
|
|
|
|
4) You should now have a complete (but very basic) root filesystem on
|
|
your harddrive. To be able to boot from floppy with this as your
|
|
root filesystem, you will have to edit the boot diskette. This is
|
|
done by modifying the word at offset 508 (decimal) with a program
|
|
such as Norton's Disk Editor, or use pboot.exe (available where
|
|
you got this file, the boot disk and the root disk, hopefully.)
|
|
|
|
This word is in 386-order (that is, least-significant byte first),
|
|
which means it should look like one of the following:
|
|
|
|
LSB MSB - device
|
|
--------------------------
|
|
01 03 - /dev/hda1 LSB = Least-Significant Byte
|
|
02 03 - /dev/hda2 MSB = Most-Significant Byte
|
|
03 03 - /dev/hda3
|
|
04 03 - /dev/hda4
|
|
|
|
41 03 - /dev/hdb1
|
|
42 03 - /dev/hdb2
|
|
43 03 - /dev/hdb3
|
|
44 03 - /dev/hdb4
|
|
|
|
The numbers are in hex, and if you're editing the boot diskette by
|
|
hand, these two bytes should initially be 00 00 (and are followed
|
|
by two non-zero bytes).
|
|
|
|
Note that pboot.exe predates Linux 0.95a, so some of the
|
|
information it presents is inaccurate (it refers to the old hd*
|
|
naming scheme). The codes to use are as above, but with the most-
|
|
significant byte first. (So /dev/hda1 = 0301, /dev/hda2 = 0302,
|
|
etc.)
|
|
|
|
5) You should now be able to boot from this diskette and it will use
|
|
your new Linux partition as the root partition. You'll notice,
|
|
however, that you can't do a whole lot with just the programs on
|
|
the root diskette. You'll need to get further packages from
|
|
whereever you got the root and boot diskettes, and read these from
|
|
a floppy using pax and compress.
|
|
|
|
(Simple instructions: Download the file to DOS, use rawrite to write
|
|
the tar file to diskette. Use 'dd if=/dev/fd[01] | uncompress | pax
|
|
-rv' to read the file from floppy, where /dev/fd0 is your first
|
|
floppy drive (A: under DOS), and /dev/fd1 is your second floppy drive
|
|
(B: under DOS).
|
|
|
|
6) To reboot your machine when running Linux, you should use the
|
|
'reboot' command. This makes sure to flush all caches to disk,
|
|
and notifies other users that the system is going down (well, the
|
|
last bit isn't real important).
|
|
|
|
FAILURE TO DO THIS COULD RESULT IN BADLY CORRUPTED FILESYSTEMS.

|
|
|
These instructions are not the best, but should be enough to get you
|
|
going. If you have more questions, either post on comp.os.linux, or
|
|
send mail to me (jwinstea@jarthur.Claremont.EDU), or to Linus
|
|
(torvalds@cc.helsinki.fi). Remember, the only stupid questions are
|
|
the ones that you don't ask.
