+HOW TO GET AND INSTALL MINIX 1.7.1
+
+This directory and subdirectories contains Minix version 1.7.1, 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:

+
+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 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.03 USR.04 USR.05
+  i86:          ROOT USR USR.01 USR.02 USR.03 USR.04 USR.05
+  xt:           README TINYROOT TINYUSR1 TINYUSR2 (360K images)
+  src:          SRC.01 SRC.02 SRC.03 SRC.04 ... 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!

+List of bugs discovered in 1.7.1.  Please report more bugs to kjb@cs.vu.nl.
+
+- The updates to the BIOS driver have only been tested on a few machines.
+  If it doesn't work on your machine then type 'processor=86' to the
+  Boot Monitor to force Minix into real mode.
+
+- The XT and PS disk drivers do not work, use the BIOS driver instead.
+
+- Disabling all WINI drivers in <minix/config.h> leads to a compilation
+  error.  (The definition of NR_TASKS in <minix/const.h> is wrong.)
+  Leave at least one of the WINI drivers enabled.
+
+- The AT disk driver uses a scratch buffer in its initialization
+  routine that has not been initialized.  This error is masked if the
+  Adaptec SCSI driver is initialized first, because it will then
+  initialize the scratch buffer for the AT driver.  This is why the
+  installation ROOT floppy works.  A kernel with only the AT driver
+  fails on an old AT disk, but an IDE disk will seemingly work.  The
+  bug will cause the driver to report wrong parameters to 'part'.
+  A fix to this bug is found in fixes/fix-1.

+Short list of differences between 1.7.0 and 1.7.1:
+
+- The BIOS driver can now operate in 286 or 386 protected mode.
+
+- Higher RS232 baud rates
+
+- More robust ethernet driver that supports the WD8003, WD8013, NE1000,
+  NE2000, and SMC Elite Ultra.
+
+- Interface to the Boot Monitor changed so that Minix can return to
+  it.  Also support for a BIOS disk I/O call added.  Minix 1.7.1 must
+  be booted by the new Monitor.
+
+- New are the Mitsumi & Soundblaster drivers.  Neither of these have been
+  tested very well after integration in 1.7.1.
+
+Long list of differences between 1.7.0 and 1.7.1:
+
+include/errno.h
+	ERROR changed into EGENERIC (symbol ERROR often used in user code,
+	although all E* symbols are reserved if <errno.h> is included.)
+
+include/unistd.h
+	Rebooting codes for various ways of rebooting added.
+
+include/minix/cdrom.h
+	For the Mitsumi CD-ROM driver.
+
+include/minix/com.h
+	Changed task number definitions of optional tasks to
+
+		#define TASK  (PREVIOUS_TASK - ENABLE_TASK)
+
+	This replaces the former #ifdef spaghetti.  The ENABLE_XXX defines
+	must be exactly 0 or 1.
+
+include/minix/config.h
+	Z_MAP_SLOTS upped to 32 to allow V2 file systems of up to 256 Mb.
+	ENABLE_XXX variables for Mitsumi CD-ROM and Soundblaster drivers
+	added.
+
+include/minix/const.h
+	NR_IOREQS symbol introduced as the maximum size of a scattered
+	I/O vector.  Vectors used to be NR_BUFS in size, which is a
+	potentionally large value.
+
+	NR_TASKS redefined as (10 + ENABLE_XXX + ENABLE_YYY + ...).
+
+include/minix/sound.h
+	For the Soundblaster driver.
+
+include/minix/syslib.h
+	Declarations for all the interface functions to the system task
+	added.
+
+include/sgtty.h
+	Definitions for higher baud rates.  (Some so high that they are
+	not likely to even work, but you can never know.)  Untested!
+
+include/sys/ioctl.h
+	Carloads of ioctl request codes added for font loading, CD-ROM,
+	and Soundblaster.
+
+man
+	Various manpages updated, several new ones for new commands.
+	The boot(8) manpage contains several new or changed boot
+	parameters, and the TCP/IP configuration section is updated for
+	the new ethernet driver.
+	New manual pages: loadfont(0), isodir(1), isoinfo(1), isoread(1),
+	mixer(1), playwave(1), cdplay(1), isoread(1), recwave(1),
+	screendump(8).
+
+src/boot/boot.c
+	Boot device name in boot monitor prompt.
+
+src/boot/boothead.s
+	Allow Minix to return to the monitor.  This means that Minix is
+	just a subprocess to the monitor.  The monitor either reboots Minix
+	(this is very fast) or shows the monitor prompt (halt).
+
+	Offer a support function for Minix-386 to make a BIOS int 13 call
+	for bios_wini.
+
+src/boot/edparams.c
+	Don't edit boot parameters unless there is a genuine Minix
+	bootstrap on the device.  Exit command to exit to Minix.
+
+src/boot/extboot.s
+	Bootstrap that boots Minix in an logical (extended) partition.
+	For if you really, really, need to have Minix in logical
+	partition.  (For the brave and foolish.)
+
+src/boot/installboot.c
+	Support for extboot.s.
+
+src/boot/masterboot.s
+	Stupid bug fixed in the "BOOT B:" trick.  (Boot the other floppy
+	if floppy 0 contains masterboot.)
+
+src/commands/aal/archiver.c
+	Use a temp file in /usr/tmp for /tmp may not be big enough to
+	contain a copy of the library.
+
+src/commands/ellec.c
+	Bug fixed to make 'ellec -Profile' work.
+
+src/commands/i386/asmconv
+	Translation of complex jmp and call targets from ACK to NCC or GNU
+	fixed.  Proper translation of CBW, CDQ, CWD, and CWDE from BAS to
+	ACK.
+
+src/commands/i86/cc.c
+	Give better advise than using chmem.
+
+src/commands/ibm
+	New commands: cdplay, loadfont, mixer, playwave, recwave.
+	Moved in from commands/simple: loadkeys, screendump, term.
+
+src/commands/ibm/fdisk.c
+	Fixed master bootstrap included.
+
+src/commands/ibm/part.c
+	User interface changed to make it tad more user friendly.  Also
+	fixed master bootstrap included.
+
+src/commands/ibm/readclock.c
+	Don't complain if the machine is not an AT or PS/2.
+
+src/commands/ibm/screendump.c
+	Mono or colour?  Just look at BIOS variable 0x40:0x63 and you know.
+
+src/commands/kermit
+	Higher baud rates.  Untested!
+
+src/commands/mined/mined1.c
+	Allow characters with bit 8 set.  (KJB's idea of internationalization
+	is that all characters with bit 8 set are letters.)
+
+src/commands/reboot/shutdown.c
+	New flags: -R: reboot with a hard reset (old style reboot),
+	           -x "boot hd1": execute this monitor code on reboot.
+
+src/commands/scripts/DESCRIBE.sh
+src/commands/scripts/MAKEDEV.sh
+	Add knowledge of /dev/cd*, /dev/audio, and /dev/mixer.
+
+src/commands/scripts/instdist.sh
+	Added more text to make it more expert hostile.  Find out what our
+	root and usr devices are.  If usr=fd0c then root is on fd0, etc.
+
+src/commands/scripts/mkdist.sh
+	Make V1 file systems to save a few bytes.
+
+src/commands/scripts/whatis.sh
+	Search expression fixed.
+
+src/commands/simple
+	New command: isoread.
+	Obsolete or useless and thus removed: fix, getlf, gres, hyphenate.
+	Moved to commands/ibm: loadkeys, screendump, term.
+
+src/commands/simple/dd.c
+	Added 'conv=silent' to suppress "records in/out" messages.  This
+	option is unportable, but useful in Minix specific scripts.
+
+src/commands/simple/file.c
+	Replaced by the Minix-386vm version for it understands more
+	executable types.  (Old file didn't know Minix-386 binaries.)
+
+src/commands/simple/in.rshd.c
+	Some port selection bug fixed.  (Je ne parle pas TCP/IP.)
+
+src/commands/simple/rarpd.c
+	Major overhaul.  Checks if networks already configured, makes RARP
+	requests, slices bread, answers RARP if /etc/ethers exists.
+
+src/commands/simple/rsh.c
+	Proper path to rlogin.
+
+src/commands/simple/vol.c
+	Added knowledge of tape block sizes.  Very useful now for compressed
+	backups to tape.  New manual page.
+
+src/fs/cache.c::rw_scattered()
+	Limit I/O vectors to NR_IOREQS blocks.  NR_IOREQS = max(NR_BUFS, 64).
+
+src/fs/const.h
+	FS_STACK_BYTES symbol removed.  FS is now loaded with a normal
+	crtso.s instead of the special head.s.  The stack size is set
+	with chmem.  The stack is allocated by the boot monitor.
+
+src/fs/file.h
+	Locking definitions moved to lock.h.
+
+src/fs/glo.h
+	The fstack array removed.
+
+src/fs/lock.[hc]
+	Locking code formerly in file.h and misc.c.
+
+src/fs/misc.c
+	Locking code moved to lock.c.
+
+src/fs/read.c
+	Bug with large pipe writes fixed.  (Return count was wrong.)
+
+	The rw_user() function removed.  All calls to rw_user() are
+	replaced by sys_copy() calls.
+
+	Read ahead limited to NR_IOREQS blocks.
+
+src/fs/table.c
+	Device table cleaned up and CD-ROM, AUDIO, and MIXER devices
+	added.
+
+src/fs/utility.c
+	The sys_xxx() functions moved to src/lib/syslib.
+
+src/inet
+	Broadcast ethernet address properly recognized, and other little
+	fixes.
+
+	Stack array removed in favour of a stack created by the monitor.
+
+src/kernel/aha_scsi.c
+	Deadly bug fixed in the CD-ROM reading code.
+	Drives larger than 1 Gb have a fake 255x63 geometry.  (This was
+	already so in the 386vm driver.  Stupid of me not to adapt this
+	one.)
+	Major overhaul to remove code that issues multiple commands to the
+	same target.  Hardly made a performance difference, but complicated
+	the code leading to crashes on moon phase changes.
+
+src/kernel/*_wini.c
+	Partititions is not speled that way.
+
+src/kernel/bios_wini.c
+	Adapted to run in protected mode.  (Both 286 and 386 protected mode!)
+	Max number of drives set to 4.
+
+src/kernel/clock.c
+	Code added to reprogram the clock to the BIOS rate at Minix halt.
+	Tricks added to collect clock ticks that get lost when the BIOS
+	driver is active.
+	New millisecond timer primitives to aid in high speed polling of
+	I/O registers.  Various drivers adapted to use them.
+
+src/kernel/console.c
+	Don't blank the screen when switching to software scrolling.  Don't
+	change the cursor shape.  Code added to load a new font into the
+	VGA card.  There are no fonts yet though.
+
+src/kernel/dp8390.[hc]
+	New ethernet driver for cards based on the DP8390 chip.
+
+src/kernel/driver.c
+	Several nop_xxx functions removed.  Tasks are now completely
+	configured out of the kernel, they no longer run a dummy loop.
+
+src/kernel/ether.[hc]
+src/kernel/hw_conf.h
+	Old ethernet driver.  Removed.
+
+src/kernel/i8259.c
+	Reprogram the interrupt controllers only if in protected mode.  In
+	real mode we use the normal BIOS interrupt vectors, and only
+	reprogram those that Minix needs.
+
+src/kernel/keyboard.c
+	CTRL-ALT-DEL now halts instead of rebooting.  (The monitor would
+	otherwise reboot Minix-386.  This is usually not what the person
+	behind the console wants.)
+
+	Reboot code changed to return to the monitor for Minix-386.  All
+	devices appropriately reprogrammed for the BIOS.
+
+src/kernel/keymaps/spanish.src
+	Modified by Javier Garcia Martin (jawa@inf.deusto.es).
+
+src/kernel/klib386.s
+src/kernel/klib88.s
+	8086 bios13 code changed to enable all unused IRQ's and to
+	disable them afterward, so that bios_wini need not know the IRQ
+	of the disk.  286 bios13 allows bios_wini to operate in
+	protected mode.  It steps back to real mode with a processor
+	shutdown, makes the BIOS call, and steps back up to protected
+	mode.  The 386 version makes a call to a monitor function that
+	makes the call using 386 ways to step in and out of real mode.
+	Don't read this code if mentally unstable.
+
+	Port_read_byte() and port_write_byte() functions added that do
+	block port I/O in byte mode.  (Needed for the NE1000 driver and
+	the Mitsumi CD-ROM driver.)
+
+	Protected mode initialization code cleaned up and calls to it
+	removed from C code.
+
+	Extended memory copy removed from klib88.s::phys_copy() for lack
+	of use.
+
+src/kernel/main.c
+	Stack pointers of servers initialized to the top of their
+	address space where the monitor has made a stack.
+
+	Stack guard words for the tasks added.  The system now panics
+	early if a tasks overruns its stack, instead of crashing in an
+	adjacent task.
+
+	Real mode vector initialization code removed.  Minix now runs in
+	real mode with only minimum changes to BIOS parameters.  All the
+	special case code for real mode is gone.  One should be able to
+	make BIOS calls from user programs, but that's just an unfortunate
+	side-effect of the cleanup.  (The BIOS disk driver is happy though.)
+
+src/kernel/mcd.c
+	Mitsumi CD-ROM driver by Michel Prevenier (mrpreve@cs.vu.nl).
+	(Andy has these fun projects for his students.  :-)  )
+
+src/kernel/memory.c
+	The RAM disk can no longer be placed in extended memory.  Minix
+	should now be able to run in protected mode on any 286 or better,
+	so we can forget about "extended memory" being special.
+
+src/kernel/mpx386.s
+src/kernel/mpx88.s
+	Flags set to tell the monitor that stacks must be made for the
+	servers, and that Minix-386 would like to return on reboot or
+	halt.  (Requires a new boot monitor, 1.7.0 monitor won't work.)
+
+	Cruft removed, protected mode initialization cleaned up.
+	Real mode int08-16 removed.
+
+src/kernel/ne2000.[hc]
+	NE1000 and NE2000 code for the ethernet driver.
+
+src/kernel/proc.c
+	Stack guard check in unready().
+
+src/kernel/ps_wini.c
+	Writing enabled, driver otherwise nonfunctional.  (See comments
+	in the file.)
+
+src/kernel/rs2.s
+src/kernel/rs232.c
+	RS232 hangup code contributed by Will Rose (cwr@cts.com).
+	Untested.
+
+src/kernel/sb16.h
+src/kernel/sb16_dsp.h
+src/kernel/sb16_mixer.h
+	Soundblaster driver by Michel Prevenier (mrpreve@cs.vu.nl).
+	Hardly tested.
+
+src/kernel/start.c
+	Several changes for the monitor return and BIOS calls.  Call to
+	sel_wini_task() removed, as the BIOS driver is now even useable
+	in 286 protected mode.  Simplyfied a bit w.r.t. real/protected
+	mode.
+
+src/kernel/table.c
+	New definitions, stack sizes, etc. for the new drivers.
+
+src/kernel/tty.c
+	New font change ioctl.  RS232 hangup.
+
+src/kernel/wdeth.[hc]
+	WD8003 and WD8013 parts of the ethernet driver.
+
+src/kernel/wini.c
+	Panic if the selected hd driver doesn't exist instead of
+	silently failing.
+	Sel_wini_task() folded into winchester_task().
+
+src/lib/*/rts/head.s
+	Removed.
+
+src/lib/other/printk.c
+	Replaced by the Minix-386vm version that is somewhat smaller
+	and somewhat more ANSI C compliant.
+
+src/lib/other/syslib.c
+	Moved to src/lib/syslib and split up.
+
+src/lib/posix/_getcwd.c
+	Initialization bug fixed.
+
+src/lib/syslib
+	All the sys_xxx() functions from other/syslib.c and the
+	utility.c files of MM and FS gathered here in separate files.
+	(Much like the system call stubs in the posix directory.)  The
+	sys_copy() function is changed to look like the former
+	mem_copy() function of MM.
+
+src/mm
+	SIGMASK changed to SIGPROCMASK in lower or upper case.
+
+src/mm/alloc.c
+src/mm/main.c
+	Get_mem() removed from main.c and built into alloc.c::mem_init().
+
+src/mm/const.h
+src/mm/glo.h
+src/mm/table.c
+	Stack stuff removed.
+
+src/mm/utility.c
+	Sys_xxx() functions moved to src/lib/syslib.  All calls to
+	mem_copy replaced by sys_copy() calls.  (Sys_copy has been
+	changed to have the same interface as old mem_copy, save a few
+	type changes.)
+
+src/tools/init.c
+	Stack array removed.  Abort signal (CTRL-ALT-DEL) now does a
+	halt.
+
+src/tools/mkboot
+	Delay added to 'make hdtest' to make it visible that another
+	device is booted.  The other device has its own set of boot
+	parameters!  Test and floppy boot device changed into file
+	systems with copies of /dev and /minix.  This script must now
+	be run as root from the start, 'su root' calls removed.

+How to upgrade from 1.7.0 to 1.7.1.
+
+- Replace the sources, that's /usr/include, /usr/man, and /usr/src, with
+  the 1.7.1 sources by extracting the SRC.nn images in the normal way.
+  (Don't forget to move or remove the 1.7.0 stuff.)
+
+- There are two ways to continue.  You can do the daring aproach and
+  type 'make install' in /usr/src to recompile everything, or you can
+  compile only the pieces you need right now to get a 1.7.1 kernel up.
+  1.7.1 compiled command should run under a 1.7.0 kernel, so there are
+  no problems there.  Let's take the careful road:
+
+- 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.
+
+- In /usr/src/commands/simple type 'make bin /usr/bin/dd'.  The next
+  step uses a new dd option.
+
+- Customize /usr/include/minix/config.h to add or remove drivers.  In
+  /usr/src/tools type 'make hdtest', or 'make fdboot'.  Test the new
+  kernel.
+
+- If the kernel works then go back to /usr/src/tools and type
+  'make bootable' to install a new boot monitor on the root partition.
+
+- Next use 'make hdinstall' to install an new kernel image on the root
+  partition.
+
+- Your system is now running 1.7.1.  You can use 'make install' in
+  /usr/src to recompile the rest if you didn't do so already.
+
+- Run 'checkhier' as root.  It suggest commands to execute to fix
+  descrepancies in the top level directory tree.
+
+- Compare all files in /usr/src/etc with those in /etc.  Some have
+  changed and should be replaced.  Be careful not to lose changes you
+  have made to files in /etc.

+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.
