This appendix explains how to install MINIX 3.
|
|
Standard MINIX 3 requires a Pentium (or compatible) with at least
|
|
16-MB of RAM, at least 200-MB of free disk space, an IDE CD-ROM and an
|
|
IDE hard disk. Serial ATA, USB, and SCSI disks are not supported at present.
|
|
For USB CD-ROMS, see the Website: \fIwww.minix3.org\fR.
|
|
|
|
\fBPREPARATION\fR
|
|
.PP
|
|
If you already have the CD-ROM (e.g., from the book), you can skip steps 1 and
|
|
2, but it is wise to check \fIwww.minix3.org\fR to see if a newer version
|
|
is available.
|
|
If you want to run MINIX 3 on a simulator instead of native, see Part V first.
|
|
If you do not have an IDE CD-ROM,
|
|
either get the special USB CD-ROM boot image or use a simulator.
|
|
|
|
.IT "Download the MINIX 3 CD-ROM image"
|
|
Download the MINIX 3 CD-ROM image from the MINIX 3 Website
|
|
at \fIwww.minix3.org\fR.
|
|
|
|
.IT "Create a bootable MINIX 3 CD-ROM"
|
|
Decompress the downloaded file.
|
|
You will get a CD-ROM image file with extension \fI.iso\fR and this manual.
|
|
The \fI.iso\fR file is a bit-for-bit CD-ROM image.
|
|
Burn it to a CD-ROM to make a bootable CD-ROM.
|
|
.PP
|
|
If you are using \fIEasy CD Creator 5\fR, select \*(OQRecord CD from CD image\*(CQ from the File
|
|
menu and change the file type from \fI.cif\fR to \fI.iso\fR in the dialog box that
|
|
appears. Select the image file and click \*(OQOpen.\*(CQ Then click \*(OQStart Recording.\*(CQ
|
|
.PP
|
|
If you are using \fINero Express 5\fR, choose \*(OQDisc Image or Saved Project\*(CQ and
|
|
change the type to \*(OQImage Files,\*(CQ select the image file and click \*(OQOpen.\*(CQ
|
|
Select your CD recorder and click on \*(OQNext.\*(CQ
|
|
.PP
|
|
If you are running Windows and do not have a CD-ROM burning program, take a look at
|
|
.br
|
|
\fIalexfeinman.brinkster.net/isorecorder.htm\fR
|
|
.br
|
|
for a free one and use it to create
|
|
a CD image.
|
|
|
|
.IT "Determine which Ethernet Chip you have"
|
|
.PP
|
|
MINIX 3 supports several Ethernet chips for networking over LAN, ADSL, and
|
|
cable. These include Intel Pro/100, RealTek 8029 and 8139, AMD LANCE,
|
|
and several 3Com chips.
|
|
During setup
|
|
you will be asked which Ethernet chip you have, if any. Determine that now by
|
|
looking at your documentation. Alternatively, if you are using Windows, go to
|
|
the device manager as follows:
|
|
.sp 1
|
|
.ta 0.9i
|
|
Windows 2000:
|
|
.br
|
|
Start> Settings> Control Panel> System> Hardware> Device Mgr
|
|
.sp 1
|
|
Windows XP:
|
|
.br
|
|
Start> Control Panel> System> Hardware> Device Mgr\s0
|
|
.ll -1i
|
|
.sp 1
|
|
System requires double clicking; the rest are single. Expand the + next to
|
|
\*(OQNetwork adapters\*(CQ to see what you have. Write it down. If you do not have
|
|
a supported chip, you can still run MINIX 3, but without Ethernet.
|
|
|
|
.IT "Partition your hard disk"
|
|
.PP
|
|
You can boot the computer from your CD-ROM if
|
|
you like and MINIX 3 will start, but to do anything useful, you have to create a
|
|
partition for it on your hard disk.
|
|
But before partitioning, be sure to \fBback up your data to an external med\%ium
|
|
like CD-ROM or DVD\fR as a safety precaution, just in case something goes wrong.
|
|
Your files are valuable; protect them.
|
|
.PP
|
|
Unless you are sure you are an expert on disk partitioning with much experience, it is strongly suggested that you
|
|
read the online tutorial on disk partitioning
|
|
at \fIwww.minix3.org/doc/partitions.html.\fR
|
|
If you already know how to manage partitions, create a contiguous chunk of free
|
|
disk space of at least 200 MB (even better: 400 MB or more).
|
|
If you do not know how to manage partitions but have a partitioning program
|
|
like \fIPartition Magic\fR, use it to create a region of free disk space of at
|
|
least 200 MB. Also make sure there is at least one primary partition (i.e.,
|
|
Master Boot Record slot) free.
|
|
The MINIX 3 setup script will guide you through creating a MINIX partition in the
|
|
free space, which can be on either the first or second IDE disk.
|
|
.PP
|
|
If you are running Windows 95, 98, ME, or 2000 \fIand\fR your disk consists of a single
|
|
FAT partition, you can use the \fIpresz134.exe\fR program on the CD-ROM
|
|
(also available at \fIzeleps.com\fR) to reduce its size to leave room for MINIX.
|
|
In all other cases, please read the online tutorial cited above.
|
|
.PP
|
|
\fBWARNING: If you make a mistake during disk partitioning, you can lose all the data
|
|
on the disk, so be sure to back it up to CD-ROM or DVD before starting.
|
|
Disk partitioning requires great care, so proceed with caution.\fR
|
|
|
|
\fBBOOTING\fR
|
|
.nr a 0
|
|
.PP
|
|
By now you should have allocated at least 200 MB of free space on your disk.
|
|
If you have not done so yet, please do it now unless there is an existing
|
|
200-MB (or larger) partition you are willing to convert to MINIX 3.
|
|
|
|
.IT "Boot from the CD-ROM"
|
|
Insert the CD-ROM into your CD-ROM drive and boot the computer from it.
|
|
If you have 16 MB of RAM or more, choose \*(OQRegular;\*(CQ
|
|
if you have only 8 MB choose \*(OQsmall.\*(CQ
|
|
If the computer boots from the hard disk instead of the CD-ROM, boot again and enter the
|
|
BIOS setup program to change the order of boot devices, putting the CD-ROM before
|
|
the hard disk.
|
|
|
|
.IT "Login as root"
|
|
When the \fIlogin\fR prompt appears, login as \fIroot.\fR
|
|
After a successful login as root, you will see the shell prompt (#).
|
|
At this point you are running fully-operational MINIX 3. If you type:
|
|
.PP
|
|
ls /usr/bin | more
|
|
.PP
|
|
you can see what software is available.
|
|
Hit space to scroll the list.
|
|
To see what program \fIfoo\fR does, type:
|
|
.PP
|
|
man foo
|
|
.PP
|
|
The manual pages are also available at
|
|
.br
|
|
\fIwww.minix3.org/manpages\fR.
|
|
|
|
.IT "Start the setup script"
|
|
To start the installation of MINIX 3 on the hard disk, type
|
|
.PP
|
|
setup
|
|
.PP
|
|
After this and all other commands, be sure to type ENTER (RETURN).
|
|
When the installation script ends a screen with a colon, hit ENTER to
|
|
continue. If the screen suddenly goes blank, press CTRL-F3 to select
|
|
software scrolling (should only be needed on very old computers).
|
|
Note that CTRL-key means depress the CTRL key and while holding it down,
|
|
press \*(OQkey.\*(CQ
|
|
|
|
\fBINSTALLING TO THE HARD DISK\fR
|
|
.nr a 0
|
|
.PP
|
|
These steps correspond to the steps on the screen.
|
|
|
|
.IT "Select keyboard type"
|
|
When you are asked to select your national keyboard, do so.
|
|
This and other steps have a default choice, in square brackets.
|
|
If you agree with it, just hit ENTER. In most steps, the default is generally
|
|
a good choice for beginners.
|
|
The us-swap keyboard interchanges the CAPS LOCK and CTRL keys, as is conventional
|
|
on UNIX systems.
|
|
|
|
.IT "Select your Ethernet chip"
|
|
You will now be asked which of the available Ethernet driver you want
|
|
in\%stalled (or none). Please choose one of the options.
|
|
|
|
.IT "Basic minimal or full install?"
|
|
If you are tight on disk space, select M for a minimal installation
|
|
which includes all the binaries but only the system sources installed.
|
|
200 MB is enough for a bare-bones system. If you have 400 MB or more,
|
|
choose F for a full installation.
|
|
|
|
.IT "Create or select a partition for MINIX 3"
|
|
You will first be asked if you are an expert in MINIX 3 disk partitioning.
|
|
If so, you will be placed in the \fIpart\fR program to give you full power to
|
|
edit the Master Boot Record (and enough rope to hang yourself).
|
|
If you are not an expert, press ENTER for the default action, which is an
|
|
automated step-by-step guide to formatting a disk partition for MINIX 3.
|
|
|
|
\fBSubstep 4.1: Select a disk to install MINIX 3\fR
|
|
.PP
|
|
An IDE controller may have up to four disks. The \fIsetup\fR script will now
|
|
look for each one. Just ignore an error messages.
|
|
When the drives are listed, select one. and confirm your choice.
|
|
If you have two hard disks and you decide to install MINIX 3 to the second one and have
|
|
trouble booting from it, please see \fIwww.minix3.org/doc/using2disks.html\fR
|
|
for the solution.
|
|
|
|
\fBSubstep 4.2: Select a disk region\fR
|
|
.PP
|
|
Now choose a region to install MINIX 3 into. You have three choices:
|
|
.sp 0.5v
|
|
(1) Select a free region
|
|
(2) Select a partition to overwrite
|
|
(3) Delete an existing partition to free up space and merge with adjacent free
|
|
space
|
|
.sp 0.5v
|
|
For choices (1) and (2), type the region number. For (3) type
|
|
.sp -0.25v
|
|
.PP
|
|
delete
|
|
.PP
|
|
.sp -0.25v
|
|
then give the region number when asked.
|
|
This region will be overwritten and its previous contents lost forever.
|
|
|
|
\fBSubstep 4.3: Confirm your choices\fR
|
|
.PP
|
|
You have now reached the point of no return. You will be asked if you want to
|
|
continue. \fBIf you do, the data in the selected region will be lost forever.\fR
|
|
If you are sure, type:
|
|
.PP
|
|
yes
|
|
.PP
|
|
and then ENTER. To exit the setup script without changing the
|
|
partition table, hit CTRL-C.
|
|
|
|
.IT "Reinstallation choice"
|
|
If you chose an existing MINIX 3 partition, in this step you will be
|
|
offered a choice between a Full install, which erases everything in the
|
|
partition, and a Reinstall, which does not affect your existing \fI/home\fR
|
|
partition. This design means that you can put your personal files on
|
|
\fI/home\fR and reinstall a newer version of MINIX 3 when it is available
|
|
without losing your personal files.
|
|
|
|
.IT "Select the size of /home"
|
|
The selected partition will be divided into three subpartitions: root, \fI/usr\fR,
|
|
and \fI/home\fR. The latter is for your own personal files. Specify how much of the
|
|
partition should be set aside for your files.
|
|
You will be asked to confirm your choice.
|
|
|
|
.IT "Select a block size"
|
|
Disk block sizes of 1-KB, 2-KB, 4-KB, and 8-KB are supported, but
|
|
to use a size larger than 4-KB you have to change a constant and recompile
|
|
the system. If your memory is 16 MB or more, use the default (4 KB);
|
|
otherwise, use 1 KB.
|
|
|
|
.IT "Wait for bad block detection"
|
|
The setup script will now scan each partition for bad disk blocks. This will take
|
|
several minutes, possibly 10 minutes or more on a large partition.
|
|
Please be patient.
|
|
If you are absolutely certain there are no bad blocks, you can kill each scan
|
|
by hitting CTRL-C.
|
|
|
|
.IT "Wait for files to be copied"
|
|
When the scan finishes, files will be automatically copied from the CD-ROM to
|
|
the hard disk. Every file will be announced as it is copied.
|
|
When the copying is complete, MINIX 3 is installed.
|
|
Shut the system down by typing
|
|
.PP
|
|
shutdown
|
|
.PP
|
|
Always stop MINIX 3 this way to avoid data loss as MINIX 3 keeps some files on
|
|
the RAM disk and only copies them back to the hard disk at shutdown time.
|
|
|
|
|
|
\fBTESTING\fR
|
|
.nr a 0
|
|
.PP
|
|
This section tells you how to test your installation, rebuild the system after
|
|
modifying it, and boot it later. To start, boot your new MINIX 3 system.
|
|
For example, if you used controller 0, disk 0, partition 3, type
|
|
.PP
|
|
boot c0d0p3
|
|
.PP
|
|
and log in as root. Under very rare conditions the drive number seen by the
|
|
BIOS (and used by the boot monitor) may not agree with the one used by
|
|
MINIX 3, in which case try other drive numbers.
|
|
This is a good time to create a root password. See \fIman passwd\fR for help.
|
|
|
|
.IT "Compile the test suite"
|
|
To test MINIX 3, at the command prompt (#) type
|
|
.PP
|
|
cd /usr/src/test
|
|
.br
|
|
make
|
|
.PP
|
|
and wait until it completes all 40 compilations.
|
|
Log out by typing CTRL-D,
|
|
|
|
.IT "Run the test suite"
|
|
To test the system, log in as bin (required) and type
|
|
.PP
|
|
cd /usr/src/test
|
|
.br
|
|
./run
|
|
.PP
|
|
to run the test programs. They should all run correctly but they can take
|
|
20 min on a fast machine and over an hour on a slow one.
|
|
\fINote\fR: It is necessary to compile the test suite when running as root
|
|
but execute it as bin in order to see if the setuid bit works correctly.
|
|
|
|
.IT "Rebuild the entire operating system"
|
|
If all the tests work correctly, you can now rebuild the system.
|
|
Doing so is not necessary since it comes prebuilt, but
|
|
if you plan to modify the system, you will need to know how to rebuild it.
|
|
Besides, rebuilding the system is a good test to see if it works. Type:
|
|
.PP
|
|
cd /usr/src/tools
|
|
.br
|
|
make
|
|
.PP
|
|
to see the various options available. Now make a new bootable image by typing
|
|
.PP
|
|
su
|
|
make clean
|
|
time make image
|
|
.PP
|
|
You just rebuilt the operating system, including all the kernel and user-mode
|
|
parts. That did not take very long, did it?
|
|
To update the boot image currently installed on the hard disk, type
|
|
.PP
|
|
make hdboot
|
|
.PP
|
|
|
|
.IT "Shut down and reboot the new system"
|
|
To boot the new system, first shut down by typing:
|
|
.PP
|
|
shutdown
|
|
.PP
|
|
This command saves certain files and returns you to the MINIX 3 boot monitor.
|
|
To get a summary of what the boot monitor can do, while in it, type:
|
|
.PP
|
|
help
|
|
.PP
|
|
For more details, see \fIwww.minix3.org/manpages/man8/boot.8.html\fR.
|
|
You can now remove any CD-ROM or floppy disk and turn off the computer.
|
|
|
|
.IT "Booting Tomorrow"
|
|
.PP
|
|
If you have a legacy floppy disk drive, the simplest way to boot MINIX 3 is by
|
|
inserting your new boot floppy and turning on the power. It takes only a few seconds.
|
|
Alternatively, boot from the MINIX 3 CD-ROM, login as bin and type:
|
|
.PP
|
|
shutdown
|
|
.PP
|
|
to get back to the MINIX 3 boot monitor. Now type:
|
|
.PP
|
|
boot c0d0p0
|
|
.PP
|
|
to boot from the operating system image file on
|
|
controller 0, driver 0, partition 0.
|
|
Of course, if you put MINIX 3 on drive 0 partition 1, use:
|
|
.PP
|
|
boot c0d0p1
|
|
.PP
|
|
and so on.
|
|
.PP
|
|
A third possibility for booting is to make the MINIX 3 partition the active one,
|
|
and use the MINIX 3 boot monitor to start MINIX 3 or any other operating system.
|
|
For details
|
|
see \fIwww.minix3.org/manpages/man8/boot.8.html\fR.
|
|
.PP
|
|
Finally, a fourth option is for you to install a multiboot loader such as
|
|
LILO or GRUB (\fIwww.gnu.org/software/grub\fR).
|
|
Then you can boot any of your operating systems easily.
|
|
Discussion of multiboot loaders is beyond the scope of this guide, but there
|
|
is some information of the subject at \fIwww.minix3.org/doc\fR.
|
|
|
|
\fBUSING A SIMULATOR\fR
|
|
.nr a 0
|
|
.PP
|
|
A completely different approach to running MINIX 3 is to run it
|
|
on top of another operating system instead of native on the bare
|
|
metal. Various virtual machines, simulators, and emulators are
|
|
available for this purpose. Some of the most popular ones are:
|
|
|
|
\(bu VMware (www.vmware.com)
|
|
.br
|
|
\(bu Bochs (www.bochs.org)
|
|
.br
|
|
\(bu QEMU (www.qemu.org)
|
|
.sp 1v
|
|
See the documentation for each of them. Running a program on a
|
|
simulator is similar to running it on the actual machine, so you
|
|
should go back to Part I and acquire the latest CD-ROM and continue
|
|
from there.
|
|
|
