Here are the release notes for the 386BSD 0.0 distribution.  Please
note the warnings that this is a very experimental release.  For
example it cannot coexist with DOS at all (Unix takes over the whole
physical hard disk).

We're working on putting the distribution on an ftp site; it's slightly
complicated since there are both 3+1/2 inch and 5+1/4 inch distributions,
in a raw binary (compressed tar) format, as well as a binary boot floppy.
You should see an announcement soon.

PS: I have no relationship with the release other than shlepping myself
    down to Cupertino to scarf it from John Sokol.

                  Release Notes on 386BSD
                         W. Jolitz


386BSD Release 0.0:
------ ------- - -

     This  is 386BSD Release 0.0, the first edition from the
386BSD project.  It comprises an entire and  complete  UNIX-
like  operating system for the Intel 80386/486 based IBM PC,
and is based almost entirely on the NET/2 release  from  the
University  of  California, which contained much of the ear-
lier freely redistributable  and  modifiable  386BSD  source
code  done  by William F. Jolitz and contributed to the Uni-
versity of California at Berkeley for distribution.

     Originally conceived by Bill and Lynne Jolitz in  1989,
the  386BSD project is an attempt to foster new research and
development in operating systems and  networking  technology
by broadening access to base technology. In cooperation with
the University of California, an advanced  operating  system
was  redesigned  by  William  F.  Jolitz  to  work on common
386-based PC's for use by smaller colleges and other  groups
that  did  not have the resources to otherwise obtain it. In
addition, starting with the NET/2 release, this software has
been released in a form that does not require license agree-
ments, non-disclosure, or other controls  that  would  limit
it's use in undergraduate teaching programs.

     Unlike  NET/2,  386BSD  Release  0.0  is a complete and
operational system, including  binaries  and  an  executable
installation  system,  but  still  available  under the same
"freely  redistributable"  terms  of  the   original   NET/2
release.  Our  forthcoming  book  on the internals of 386BSD
will complete the picture for educational and research  pro-
grams  to make use of this technology with students with the
necessary academic freedom.

     We have been writing a series of articles about  386BSD
that  have  appeared  in  Dr. Dobbs Journal since January of
                          --  ----- -------
1991. Future announcements, and information on 386BSD may be
found  within  its covers. The DDJ BBS should have copies of
binary and source code when available. Also, you can contact
us via the magazine.

Contents:
--------

     Release 0.0 consists of:

Source Distribution
     A  collection  of  8  or  10 high-density floppy disks,
     which is a multi-volume compressed TAR  format  archive
     of the source language files with which to recreate the
     system.    When   extracted,    the    files    consume


386BSD RELEASE NOTES          1                   March 1992










     approximately  31 MB of space. In addition, at least 28
     MB of space is taken up by  the  binary  files  created
     when recompiling.

Binary Distribution
     A  collection of 6 or 8 high-density floppy disks, also
     in compressed multi-volume  TAR  form,  containing  the
     executable,  data, and documentation files of a working
     386BSD  system,  including  C  and  C++  compilers  and
     libraries.   When  extracted, the files occupy approxi-
     mately 20 MB of disk space. Note that at least 5 MB  of
     swap space, plus an operating reserve of another 10% of
     the total accumulated disk space  mentioned  should  be
     considered as minimum to operate this system.

Distribution Installation Floppy System
     A  single  floppy  system is provided, again on a high-
     density diskette.  This  completely  standalone  system
     manages  to  allow  a  potential 386/486 based PC to be
     qualified for use with 386BSD, simply by attempting  to
     boot it as an ordinary floppy. Once operational, it can
     be used to configure the PC's hard disk  and  load  the
     binary  floppy  distribution.  In addition, this floppy
     provides a means to rescue and repair the  software  on
     the hard disk in the event of a calamity.

Difference Floppy
     A  single  360 KB MS-DOS floppy containing all the dif-
     ferences and new files necessary to make the NET/2 tape
     operational,  for  those  who already have the tape and
     wish to "do it themselves". It also  serves  to  illus-
     trate  just  what  is  necessary to make the NET/2 tape
     usable and worthwhile.

     Release 0.0 does not contain any proprietary code,  nor
any  encryption software. It was created from NET/2, GNU and
other public software, and our creative minds.

Scope and Goals of this Release:
----- --- ----- -- ---- -------

     This release was motivated by the fact that  access  to
386BSD  has not been provided to all interested parties on a
timely basis by the University or other sources, as  we  had
originally  intended.   Thus, we have done a minimalist ver-
sion to demonstrate feasibility, provide accessibility,  and
assure  our readers and supporters that this project will be
finished, available to all, and  not  just  appropriated  by
private  concerns.   Since  it is minimalist by design, many
features, utilities and other functionality will  be  desir-
able  to  add,  although the system is complete enough to be
self-sufficient and self-developing.




386BSD RELEASE NOTES          2                   March 1992










     In addition, we have not repaired numerous  known  bugs
present  -- we have merely attempted to work around them and
in spite of them. Also, new  subsystems  created  after  the
NET/2  tape  and contributed to Berkeley have not been added
back in, because we did not want to blur the distinctions of
what is required to make NET/2 operational, and because CSRG
will not allow us access to this contributed work,  although
other  groups  have  been  allowed  access.  Future releases
hopefully will remedy these nuisances. We  also  expect  the
involvement  of  a  wider  community of users will aid us in
improving future releases of 386BSD.

Devices Supported in this Release:
------- --------- -- ---- -------

     This release is intended to support a  minimal  386/486
SX/DX  ISA(ATBUS)  system,  with  the  traditional  hard and
floppy disk controller (MFM,ESDI,IDE).  Also, the usual dis-
play  adapters  (MDA/CGA/VGA/HGC)  are supported, along with
the communications ports (COM).  Ethernet  controllers  sup-
ported   are    Western   Digital  8003EB,  8003EBT,  8003S,
WD8003SBT, 8013EBT, and Novell NE2000. Clones also appear to
work quite well.  Tape drive support is available for QIC-02
controllers as well, allowing use of 3M cartridges of QIC-60
through QIC-150 format.

     As  configured  on  the binary distribution, the system
requires a floating point coprocessor  (387  of  any  make),
hard  disk and controller, floppy disk drive (either 5.25 or
3.5 high density only), and display adapter. If  the  serial
port  or a Western Digital Ethernet card (port 0x280, IRQ 3,
iomem 0xd000) is present, the system can make use of  it  as
well.

     It  is recommended that the system have at least 2MB of
memory or more, but it will run on much smaller systems to a
limited  degree  by paging (the C++ compiler uses about 1 MB
of memory in operation).  A 4 MB system with an 200 MB+  IDE
disk is a comfortable configuration, although by sharing the
sources via NFS, networked systems with  40  MB  drives  are
quite useful.

Machines Tested:
-------- ------

     At  the  moment,  this software has only been tested on
the following configurations:

Toshiba laptop clone, 386SX/387SX, 3MB RAM, VGA LCD(Cirrus),
     Megahertz T2LL Ethernet, Conners CP3100 IDE 100MB drive.

Compaq DeskPro, 386/387, 9MB RAM, Compaq VGA, ESDI Maxtor 8380 drive(type 38),
     WD8003EBT Ethernet, Compaq QIC-150 cartridge drive.




386BSD RELEASE NOTES          3                   March 1992










     Please fill out the enclosed registration form and sur-
vey so we can add more to this test base list. It is expect-
ed that all Compaq, Toshiba, Chips and Technology-based, and
OPTI-based  systems should work with little trouble. See up-
coming DDJ articles on installation troubles for further in-
fo.   We  can be contacted for limited help with the system,
but, realize that this work is currently unfunded and we can
only devote a tiny amount of time to it. As a hint to fixing
troubles, defeating options like shadow ram or RAM  BIOS  is
an excellent place to start.

Installation Procedures:
------------ ----------

     Currently, the system does not coexist with MS-DOS, but
requires the entire machine. SINCE IT IS STILL  EXPERIMENTAL
SOFTWARE,  YOU  SHOULD  BE  PREPARED AT ANYTIME TO LOSE DISK
DRIVE CONTENTS, so you had better save backup dumps  offline
of any information you wish to be preserved (1 in 100 of you
will do this, of course, but you were warned).

     First, make a copy of all of  the  diskettes  and  save
them away. Make many copies of the distribution installation
diskette, and salt them away in various places, as it is im-
possible to recover the system without one otherwise.

     The  distribution  installation diskette has predefined
shell variables that correspond to the device name  for  the
floppy  drive  ($FD), the raw device name ($RFD), the amount
of storage ($FTRK) per track (in kilobytes), and the disktab
entry type ($FT). These are present to parameterize the dif-
ferences between 3.5 inch and 5.25 inch versions of the boot
floppy.

     Format  the  drive, if it is not already. Determine the
geometry (sectors/track, tracks/cylinder, number  of  cylin-
ders,  etc),  and create a disktab entry describing the disk
drive in the /etc/disktab file on the floppy.  This  can  be
done by allowing the floppy to be written to (it defaults to
disabling writing) by the command:

mount -u $FD /

     You can edit the file with the elvis editor, a clone of
                                    -----
the  encumbered  Berkeley vi text editor done by Steve Kirk-
                          --
endall.  You may wish to use one of the existing disktab en-
tries  as  a template for a new entry you are making. Please
include any disktab entrys you make in the survey form so we
can  include them in the next release.  Note: after you have
written the disk, please execute the "sync" command so  that
the file will be forced back to the diskette.

     Next,  use  the  disklabel command to write a bootstrap
                      ---------
and disk label data structure on the hard disk itself.  This


386BSD RELEASE NOTES          4                   March 1992










will destroy any information present on the beginning cylin-
der of the hard disk drive. A sample disklabel command:

disklabel -r -w wd0 cp3100    (label winchester drive 0 as a conners 3100)
disklabel -r wd0         (display the label on winchester drive 0)


     Next, create empty filesystems for the root  (partition
a  of  the  drive) and usr (partition h) with the newfs com-
                                                  -----
mand:

newfs wd0a     (root partition high level format)
newfs wd0h     (usr partition high level format)


     Mount the root partition and transfer the  contents  of
the distribution installation floppy to the hard drive. This
step frees up the floppy for use in loading the multi-volume
distribution while running off the hard disk drive:

mount /dev/wd0a /mnt  (associate the mnt directory with the new root filesystem)
(cd /; tar -cf - .) | (cd /mnt; tar -xf -)   (copy floppy to hard disk)
sync                          (flush out written blocks)

     Reboot  the  system  by  the  traditional cntrl-alt-del
three-fingered reset, and  remove  the  floppy  and  set  it
aside.  The  system  should  now  come  up off the hard disk
drive. Next, we load the distribution by inserting the first
floppy (volume 1 of the binary distribution) and typing:

mount /dev/wd0h /usr (make usr filesystem available, as it will also be loaded)
mr $FTRK $RFD | tar -xzf -  (floppy extract compressed floppy archive)


     A prompt will ask for successive floppies to be insert-
ed into the drive.  At the conclusion,  the  "sync"  command
should be used, and the system rebooted. The installation is
now complete, and the same procedures may be  used  at  this
point to extract the source distribution if desired.

Operation:
---------

     At  the  moment,  386BSD  comes up single user, and re-
quires manual starting of the system  daemons,  as  well  as
filesystem  checks. In use, one would minimally wish to type
after booting:

fsck -p
mount -a
update
/etc/netstart




386BSD RELEASE NOTES          5                   March 1992










     This will improve in forthcoming  versions  of  386BSD.
Be  aware  that  the  user is running as the super-user, and
care should be taken given the maximum privileges present.

Known bugs:
----- ----

     Many bugs and unimplemented portions of the system  ex-
ist  and  can  be  annoying. The most irritating are the tty
driver bugs that are  related  to  boundaries  in  the  ring
buffers,  which cause the input queue to become truncated or
wrapped, as well as freezing the input queue when a  transi-
tion  to  RAW  mode  occurs  near a boundary (generally, the
first time the command  "more"  prompts).  Usually,  hitting
control-C clears this situation.

     Sometimes,  an  endless  end-of-file  on input from the
terminal occurs that may require the  system  to  be  reset.
There  is  a pipe bug, believed to be in the block I/O code,
that breaks large pipe transfers into ~3  KB  maximum  sized
chunks.   Occasionally,  a  missing interrupt bug causes the
system to  jam  waiting  for  an  interrupt  that  has  been
botched.   Init  does  not handle signals and process groups
correctly, nor does it support multiuser operation (you  can
start  up other users by hand, or over the network as incom-
ing terminal sessions!).  Execve will not run shell scripts,
nor  will it work with arglists greater than 2 KB.  There is
no facility for program debugging (e.g.  ptrace).   Raw  DMA
transfers  to non-page aligned, non-consecutive within 64 KB
physical boundaries don't work correctly.  The console  ter-
minal emulator destroys screen contents occasionally.  A re-
dundant swap free fragment bug is  present  under  intensive
paging operations, and resource constipation due to hundreds
of processes on tiny machines does occur.  Operation on less
than  2MB  may  be  erratic or impossible due to a base page
memory botch present.

     All of these bugs are understood. Some of the fixes re-
quire  redesign  while  others require code from the article
series!, but we are sure more are present.  Bug  fixes  will
be put into subsequent versions.

Key Missing Utilities:
--- ------- ---------

     Among  the  most  annoying  missing utilities are: awk,
grep, sort, diff, test, and expr.  The utility software  has
been cudgeled to ignore these for the moment, but eventually
these must be rectified. All of  the  NET/2  utilities  have
been  made  to work with 386BSD, including those not present
in this release due to space considerations. You  will  find
it  fairly  painless  to  add  software to this base system,
which is still at heart a full 32-bit POSIX compliant  oper-
ating system with program development environment.



386BSD RELEASE NOTES          6                   March 1992










     Note  also  that  DES encryption and Kerberos have pur-
posely been left off the system to allow  for  international
use, as 386BSD incorporates software (such as NFS) which has
been done by researchers in other countries and  contributed
to  Berkeley.  For those international readers who have con-
sidered obtaining the NET/2 tape from UCB, it might interest
them  to know that an export license (GTDA) has been granted
for a version of the NET/2 tape.

Future
------

     Your interest, involvement, and support in this project
and  its  goals will determine the future of 386BSD and suc-
cessive releases. We would like to take this  much  further,
but  we  need  considerable assistance of all kinds to allow
386BSD to grow further. We realize the shortcomings  of  Re-
lease  0.0,  but  are intensely proud of what we have accom-
plished in providing you with a chance  to  become  involved
with a system that has enough tools to develop itself.

I would like to comment on one portion of the 386 Release Notes recently
posted in this newsgroup, as I think that it could possibly be misunderstood.
The sentences that caught my attention were:

	Also, new subsystems created after the NET/2 tape and contributed
	to Berkeley have not been added back in, because we did not want
	to blur the distinctions of what is required to make NET/2
	operational, and because CSRG will not allow us access to this
	contributed work, although other groups have been allowed access.

While it is true that some people have access to software contributed to
Berkeley before it is officially released by the University, this access
is in the form of an account on one of the CSRG's development machines.
These accounts have the explicit restriction that source may not be copied
from the machine without written or electronic permission from a member
of the CSRG.  Usually, this type of access is provided to groups that are
funding our efforts or individuals with whom we are collaborating.

The system at Berkeley continually changes.  As a group of three and a
half people, we do not have the time to make a distribution each time a
significant change is made.  We try to be responsive to specific requests
by sending updates to UUNET for their ftp archives.

To the best of my knowledge, NO software has been made available to any
organization for redistribution (including those which fund us) without
also making it freely available to everyone either as part of an official
BSD release or by placing it for anonymous ftp on uunet.uu.net.

I cant help but notice from many of your postings. . . Three and a half
people. Does this mean three people working full time and a part timer
like a 20 hour per week grad student? Or does it mean three people
who are unix guru's and one person who is just learning unix having
graduated from dos or worse cics?

Yes.  We have three full-time staff people, and half of the time of a
fourth staff person.  That's the reason that we make such a point of
giving credit to the UNIX community in our releases -- they do the
work!  Three and a half people, no matter how dedicated, can't possibly
generate or maintain the amount of software included in the 4BSD
system.  The contributed software acknowledgements for NET/2 listed
roughly 150 separate contributions.

Speaking of which, we're always looking for volunteers to work on the
project!  ;-}
