+HOW TO GET AND INSTALL MINIX 1.7.2
+
+This directory and subdirectories contains Minix version 1.7.2, a small
+educational UNIX-like system for IBM PC's and compatibles. 
+
+Before installing Minix, do the unthinkable and read the installation
+manual in the file usage.8. On a UNIX machine you can unpack 
+man.tar.Z and use a reasonably smart pager (one that understands
+backspace overstrikes) to read the man pages. The same manual pages
+can be found in man.zip as flat text for use under MS-DOS. Note that the
+ZIP file contains subdirectories that you may or may not want to keep
+intact. 
+
+  man.tar.Z             - Installation manual pages (UNIX)
+  man.zip               - Installation manual pages (MS-DOS)
+
+Alternatively, by WWW you can view the whole manual page set. The
+page to start with is usage(8). 
+
+Before fetching Minix, you should get the checksum list (to verify correct
+transmission and unpacking). If you do not already have it, you will need
+the program to compute the checksums on your machine, crc.c: 
+
+  crclist               - CRC's of all the files here
+  crc.c                 - Command to make CRC checksums
+
+Eventually, you may also want these files: 
+
+  changes-1.7.2         - List of changes between 1.7.1 and 1.7.2
+  upgrade-1.7.2         - How to upgrade from 1.7.x to 1.7.2
+  bugs                  - List of bugs in 1.7.2
+  fixes/                - Fixes to bugs in 1.7.2
+
+
+Minix for the Intel architecture comes in three flavors: 
+
+   - Regular (for 386, 486, and Pentium machines)
+   - Small (for 8086 and 286 machines)
+   - Tiny (for 8086 and 286 machines with small memories and/or 360K
+     diskette drives)
+
+For the regular distribution, use the i386 directory. For the small
+distribution, use the i86 directory. For the tiny distribution, use the both
+the i86 and xt directories. All these directories contain the executable
+programs of Minix. In addition, the src directory contains the full Minix
+source code, which is identical for all three flavors (the code contains
+#ifdef's where the difference matters). 
+
+Two versions of the distribution have been prepared. If you are
+reasonably experienced in dealing with UNIX or Minix and are
+downloading to a UNIX or Minix system with 10MB of free disk space,
+and a connection that can transfer megabyte files without loss (even if
+this is not the target system), just fetch whichever of the following you
+need: 
+
+  i386.tar      - 386 binaries
+  i86.tar       - 8086/286 binaries
+  xt.tar        - Replacement files for tiny systems
+  src.tar       - Full sources and manual pages for all versions
+
+Under all other circumstances, use the second distribution, which
+consists of many 720K floppy disk images (you can also use bigger
+diskettes, but remember that the size of the images is still 720K). 
+
+  i386:         ROOT USR USR.01 USR.02 ... USR.06
+  i86:          ROOT USR USR.01 USR.02 ... USR.06
+  xt:           README TINYROOT TINYUSR1 TINYUSR2 (360K images)
+  src:          SRC.01 SRC.02 ... SRC.08
+
+The USR.nn and SRC.nn series of diskette images were created by
+commands like this one, so they are just a compressed tar file cut to
+pieces: 
+
+        tar cf - * | compress | vol 720 /dev/fd0
+
+The two installation floppies can be combined on a 1.2 Mb or 1.44 Mb
+diskette, the other images can be combined on 1.44 Mb floppies, turning
+them into 1440K images: 
+
+        cat ROOT USR >/dev/fd0
+        cat USR.01 USR.02 >/dev/fd0              (odd/even pairs)
+        cat USR.03 USR.04 >/dev/fd0
+        ...
+        cat SRC.01 SRC.02 >/dev/fd0
+        ...
+
+/dev/fd0 is a random floppy device name. You have to find out what your
+Operating System names it today. Under MS-DOS you can use the 
+WrtDsk command in the ../dosutil directory to write the floppy images. 
+
+Be careful when you install Minix, many of the commands are
+potentionally dangerous in a way that a simple typing mistake may
+destroy all other data on your system. So make backups first!

+How to upgrade from 1.7.x to 1.7.2.
+
+Note: Things you have to do as root are marked with a # sign.  The ! sign
+marks the actions of bin.
+
+# Replace the sources, that's /usr/include, /usr/man, and /usr/src, with
+  the 1.7.2 sources by extracting the SRC.nn images in the normal way.
+  (Don't forget to move or remove the 1.7.x stuff.)
+
+# First remove the encrypted passwords from the password file.  1.7.2
+  encrypts and checks passwords differently.
+
+! Almost all 1.7.2 compiled commands should run under a 1.7.x kernel,
+  and vice-versa.  The the new stty and loadkeys commands will only run
+  under 1.7.2, so make copies of them.  The old loadkeys command cannot
+  run under the new kernel, so you have to compile a new loadkeys if you
+  need it.  The mkfs command can only run well under the kernel it is
+  compiled under.  If you follow this text point by point then the old
+  mkfs will be used for 'make hdtest', and the new mkfs will be created
+  once the 1.7.2 kernel is running when the commands are recompiled.
+
+! Move to /usr/src/lib and type 'make install'.  You need new libraries
+  for the new kernel.
+
+! In /usr/src/boot type 'make install'.  The new kernel needs a new boot
+  monitor.  (The 1.7.1 monitor can only boot 1.7.2 on an AT.)
+
+# Copy /usr/src/etc/ttytab to /etc.  The ttytab file replaces /etc/ttys &
+  /etc/ttytype in 1.7.2.  You need ttytab or you can't login!  Also update
+  the RAM disk image if you are using the RAM disk:
+  	# M root
+  	# synctree /etc /root/etc
+  	# U root
+
+! If you are running 1.7.0 now then move to /usr/src/commands/simple and
+  type 'make bin /usr/bin/dd'.  The next step uses a new dd option.
+
+# The tty devices have changed in 1.7.2, so you have to create new ones:
+	# cd /dev
+	# sh /usr/src/commands/scripts/MAKEDEV.sh log tty00 tty01
+  MAKEDEV is not installed yet, so you have to use this long name.  The
+  tty0 - tty2 devices are now obsolete, you can remove them later.  If you
+  have a RAM disk then update the /dev on the image as shown above for

+Suggestions on installing Minix on a machine with little memory.
+
+The file TINYROOT is a small replacement for the ROOT image that is
+needed if your machine has only one floppy drive and less than 2
+megabytes of memory.  You can use it to boot your machine, but you
+should use ROOT for the installation if you can.
+
+If your floppy drive is only 360 kb then have to use TINYROOT for ROOT,
+and TINYUSR1 for USR.  The very last step of the installation, filling
+/usr from USR.nn, will fail, because you need some commands that are on
+TINYUSR2.  You have to copy those commands into the /usr tree (mount the
+floppy and cpdir the lot).  TINYUSR2 also contains the kernel image
+used for TINYROOT in the tmp directory that you can use as /minix.
+
+A machine with only 640 kb memory will have trouble to run the
+installation script.  Use
+
+	exec instdist
+
+to overlay the login shell of root with the script.  The USR.nn and
+SRC.nn images can be split in two 360 kb pieces with the commands:
+
+	dd if=image of=first-half bs=1k count=360
+	dd if=image of=second-half bs=1k skip=360
+
+If you want to compile a new kernel as bin use
+
+	chsh /bin/sh
+
+to change the login shell of bin from ash to the much smaller sh.  Log
+out, log back in, and use
+
+	exec make xxx
+
+If it still fails then you have to make things bit by bit by running
+make in subdirectories.
+
+Note that you are on your own in this enterprise, anyone mad enough to
+still use an XT had better be smart enough to find his own way.  Testing
+the TINYXXX stuff has consumed enough of my time.  If you still dare to
+ask me questions then you'd better make it very interesting questions.
