(Forwarded from the linux-m68k mailing list)

[This is a rough draft of the announcement.  Please check it to make
 sure I haven't misspelled Linus's name and all the other stupid things
 I usually do when I write stuff :)]

The Linux/m68k development community is pleased to announce the first
"stable" release of Linux 2.0 for Motorola 68000-based systems.  The
basic kernel sources include support for Atari ST-series and Amiga
computers.  There is also a port to the Motorola VME 162, 166 and 167
boards available (see below for contact information).

Linux is an implementation of the Unix operating system that has been
made freely available under the GNU Public License.  It was originally
written for Intel 80386 processors by Linus Torvalds, and has been
subsequently ported to run on Motorola 68000 series, SPARC, MIPS,
PowerPC and Alpha processors.  For more details on Linux in general,
we refer you to the Linux Documentation Project (see below for
addresses).


What's New in 2.0
-----------------

The major changes since the last stable Linux/m68k release, version
1.2.13pl10, include the following:

* Harmonization with the mainstream Linux source tree.  By release
  2.2.0 of the main Linux source tree, the Linux/m68k kernel
  will be distributed as part of it.

* Support for more filesystem types.  Amiga filesystem support now
  includes both reading and writing to all types except AmigaOS 3.x
  Directory Cache filesystems, and is substantially faster.

* The ext2fs (Linux's native filesystem) has been changed so that all
  CPUs use a common bit-order.  Backwards compatibility is retained
  with the Linux/m68k 1.2.13pl4 filesystem format; the new ext2fs
  utilities allow older filesystems to be converted to the common
  format.

* Many more kernel components can be built as modules.  For example,
  if you have a mostly ELF-based system, you can remove the a.out
  support from the kernel proper into a module.  The a.out module can
  be demand-loaded by the kerneld daemon as needed.  [You must include
  support in the kernel for whatever format your init program is in.]

* The Point to Point protocol has been improved.  A new release of the
  pppd program is required for it to work (see below).

* Networking has changed significantly.  You will need to update your
  basic networking utilities (ping, traceroute, etc.) when you start
  using 2.0.

* The bdflush daemon has been integrated into the kernel.

* Many other goodies have been added that may only be of interest to a
  few people.  Filesystem quotas are now supported, as are IP
  firewalling and masquerading, disk striping, (R)ARP, process
  accounting.

* New hardware support for Linux/m68k since 1.2.13pl10 includes:
  - 68060 processor support
  - Cyberstorm and Blizzard 2060 SCSI modules [Amiga]
  - GVP Combo SCSI cards [Amiga - all with wd33c93 controllers]
  - Color on OCS and ECS displays [Amiga]
  - Hard drives partitioned under MS-DOS
  - Parallel port on the Multiface III card [Amiga - serial was
     supported in 1.2.13pl10]
  - ATAPI IDE CD-ROM support [tested only on Atari]

* Hardware support not included in 2.0.22 but available elsewhere:
  - Blizzard 1230 SCSI adapter [Amiga - in 2.0.23?]
  - Floating Point emulation [copyright issues prevent its inclusion
     in the distributed kernel tree]

* In the works:
  - Apollo Domain workstation support
  - Apple Macintosh support
  - Sun 3 support
  - Cirrus Logic-based graphics cards for the Amiga [Picasso, Piccolo]
  - TMS 34010-based graphics cards for the Amiga [A2410, DMI Resolver]
  - Atari TOS and AmigaOS emulators


How to get upgraded software
----------------------------

If you haven't already upgraded to ELF, the best way is to back up
your user directories, repartition (if you like) and get the
Watchtower-2 filesystems.  These include all the software you need to
upgrade to 2.0.

If you already are running an ELF system, you'll need:

pppd version 2.2.0f or later
sysvinit version 2.60 or later
procps 1.01 or later
modules 2.0.0 or later (only if you are using modules)
NetTools 1.32alpha or later

You may need other packages as well depending on your configuration.
See the file 'Documentation/Changes' in the kernel source tree for
details.

 make sure I haven't misspelled Linus's name and all the other stupid
 things I usually do when I write stuff :)  Please do not repost this
 elsewhere.]

The Linux/m68k development community is pleased to announce the first
"stable" release of Linux 2.0 for Motorola 68000-based systems.  The
basic kernel sources include support for Atari ST-series and Amiga
computers.  There is also a port to the Motorola VME 162, 166 and 167

written for Intel 80386 processors by Linus Torvalds, and has been
subsequently ported to run on Motorola 68000 series, SPARC, MIPS,
PowerPC and Alpha processors.  Work is in progress on ports to the
Acorn ARM and Intel 8086 processors.  For more details on Linux in
general, we refer you to the Linux Documentation Project (see below
for addresses).


What's New in 2.0
-----------------

The major changes since the last stable Linux/m68k release, version
1.2.13pl10, include the following:

* System response time is somewhat faster.  The kernel can now be
  compiled for a specific CPU, saving some runtime checks that cause
  performance losses (particularly in the memory management code).
  Specific 68040 and 68060 optimizations are optional.

* Harmonization with the main Linux source tree.  This allows future
  releases of Linux/m68k to be made nearly in sync with Linux/i386
  releases (within a few days in most cases).

* Support for more filesystem types.  Amiga filesystem support now
  includes both reading and writing to all types except AmigaOS 3.x
  Directory Cache filesystems (these are read-only), and is
  substantially faster. 

* The ext2fs (Linux's native filesystem) has been changed so that all
  CPUs use a common bit-order.  Backwards compatibility is retained
  with the Linux/m68k 1.2.13pl4 filesystem format; the new ext2fs
  utilities allow older filesystems to be converted to the common
  format.  Upgraders should use the new ELF ramdisk for installation.

* Many more kernel components can be built as modules.  For example,
  if you have a mostly ELF-based system, you can remove the a.out
  support from the kernel proper into a module.  The a.out module can
  be demand-loaded by the kerneld daemon as needed.  [You must include
  support in the kernel for whatever format your init program is in.]

* The Point to Point protocol has been improved.  A new release of the
  pppd program is required for it to work (see below).

* Networking has changed significantly.  You will need to update your
  basic networking utilities (ping, traceroute, etc.) when you start
  using 2.0.

* Many other goodies have been added that may only be of interest to a
  few people.  Filesystem quotas are now supported, as are IP
  firewalling and masquerading, disk striping (RAID0), (R)ARP, and
  process accounting.  NFS support has improved to the point where it
  is possible to boot from NFS volumes.

* New hardware support for Linux/m68k since 1.2.13pl10 includes:
  - 68060 processor support
  - Cyberstorm and Blizzard 2060 SCSI modules [Amiga]
  - All GVP SCSI adapters [except new 68060 card and old Series I]
  - Color on OCS and ECS displays [Amiga]
  - Hard drives partitioned under MS-DOS
  - Parallel port on the Multiface III card [Amiga - serial was
     supported in 1.2.13pl10]
  - ATAPI IDE CD-ROM support

* Hardware support not included in 2.0.22 but available elsewhere:
  - Blizzard 1230 SCSI adapter [Amiga] (or is it -- Jesper?)
  - Floating Point emulation [copyright issues prevent its inclusion
     in the distributed kernel tree]

* In the works:
  - Apollo Domain workstation support
  - Apple Macintosh support
  - Sun 3 support
  - Cirrus Logic-based graphics cards for the Amiga [Picasso, Piccolo, SD64]
  - Atari TOS and AmigaOS emulators


Command line changes
--------------------

The kernel command line has changed somewhat:

* Atari users: the 'atavideo' parameter is now simply 'video', like on the
  Amiga.  See 'Documentation/m68k/kernel-options.txt' for some new parameters
  that are supported.

* If you are booting from a ramdisk, you must now specify the root device
  or else the kernel will not boot.

  Instead of:
    amiboot -r ramdisk-name video=vga70
  Use:
    amiboot -r ramdisk-name video=vga70 root=/dev/ram

* GVP SCSI users shouldn't need the gvp11 parameter any more; the driver now
  auto detects the DMA range that each SCSI controller is capable of using.

If you haven't already upgraded to ELF, the best way is to back up
your user directories, repartition (if you like) and get the

[This is yet another rough draft of the announcement.  I think I've
 addressed most of the concerns expressed before; let me know if I got
 anything else wrong :)]

The Linux/m68k development community is pleased to announce the first
"stable" release of Linux 2.0 for Motorola 680x0-based systems.  The
basic kernel sources include support for Atari ST-series and Amiga
computers.  There is also a port to the Motorola VME 162, 166 and 167

Linux is an implementation of the Unix operating system that has been

subsequently ported to run on Motorola 680x0 series, SPARC, MIPS,
PowerPC and Alpha processors.  Work is in progress on ports to the
Acorn ARM and Intel 8086 processors.  For more details on Linux in
general, we refer you to the Linux Documentation Project (see below
for addresses).

Linux/m68k runs on the following CPUs: 68020 (with 68851 MMU), 68030
(not 68EC30), 68040 (not 68EC040 -- see below for 68LC040), and 68060.
It does not run on the 68000 and 68010, because those systems have no
Motorola-supported MMUs.

For 68020, 68030, and 68LC040 users: The main distribution of the
kernel only works on systems with FPUs.  There are kernels available
with FPU emulation, however.

  (read/write except DirCache partitions, which are read-only).

* The ext2fs (Linux's native filesystem) has been changed so that all
  CPUs use a common byte-order.  Backwards compatibility is retained
  with the Linux/m68k 1.2.13pl4 filesystem format; the new ext2fs
  utilities (versions 1.05 and later) allow older filesystems to be
  converted to the common format.  Upgraders should use the new ELF

(Forwarded from the linux-m68k mailing list)

I believe this version incorporates all of the proposed changes that were
made.  The question of a release date still seems important: I know that
we will be releasing a "final" 2.0 series kernel soon, and I'd like to
have this out within a few days of that release (just enough time so we
obviously haven't made a major boo-boo).

[Begin]
The Linux/m68k development community is pleased to announce the first
"stable" release of Linux 2.0 for Motorola 680x0-based systems.  The
basic kernel sources include support for Atari ST-series and Amiga
computers.  There is also a port to the Motorola VME 162, 166 and 167
boards available (see below for contact information).

Linux is an implementation of the Unix operating system that has been
made freely available under the GNU Public License.  It was originally
written for Intel 80386 processors by Linus Torvalds, and has been
subsequently ported to run on Motorola 680x0 series, SPARC, MIPS,
PowerPC and Alpha processors.  Work is in progress on ports to the
Acorn ARM and Intel 8086 processors.  For more details on Linux in
general, we refer you to the Linux Documentation Project (see below
for addresses).

Linux/m68k runs on the following CPUs: 68020 with 68851 MMU, 68030
(not 68EC30), 68040 (not 68EC040 -- see below for 68LC040), and 68060.
It does not run on the 68000 and 68010, because those systems have no
Motorola-supported MMUs.

For 68020, 68030, and 68LC040 users: The main distribution of the
kernel only works on systems with FPUs.  There are kernels available
with FPU emulation, however.


What's New in 2.0
-----------------

The major changes since the last stable Linux/m68k release, version
1.2.13pl10, include the following:

* System response time is somewhat faster.  The kernel can now be
  compiled for a specific CPU, saving some runtime checks that cause
  performance losses (particularly in the memory management code).
  Specific 68040 and 68060 optimizations are optional.

* Harmonization with the main Linux source tree.  This allows future
  releases of Linux/m68k to be made nearly in sync with Linux/i386
  releases (within a few days in most cases).

* Support for more filesystem types.  Amiga filesystem support now
  includes both reading and writing to all types except AmigaOS 3.x
  Directory Cache filesystems (these are read-only), and is substantially
  faster.  The driver also supports Amiga MultiUserFileSystem volumes
  (read/write except DirCache partitions, which are read-only).

* The ext2fs (Linux's native filesystem) has been changed so that all
  CPUs use a common byte-order.  Backwards compatibility is retained
  with the Linux/m68k 1.2.13pl4 filesystem format; the new ext2fs
  utilities (versions 1.05 and later) allow older filesystems to be
  converted to the common format.  Upgraders should use the new ELF
  ramdisk for installation.

* Many more kernel components can be built as modules.  For example,
  if you have a mostly ELF-based system, you can remove the a.out
  support from the kernel proper into a module.  The a.out module can
  be demand-loaded by the kerneld daemon as needed.  [You must include
  support in the kernel for whatever format your init program is in.]

* The Point to Point protocol has been improved.  A new release of the
  pppd program is required for it to work (see below).

* Networking has changed significantly.  You will need to update your
  basic networking utilities (ping, traceroute, etc.) when you start
  using 2.0.

* Many other goodies have been added that may only be of interest to a
  few people.  Filesystem quotas are now supported, as are IP
  firewalling and masquerading, disk striping (RAID0), RARP, and
  process accounting.  NFS support has improved to the point where it
  is possible to boot from NFS volumes.  See the Documentation
  directory of the kernel source for details.

* New hardware support for Linux/m68k since 1.2.13pl10 includes:
  - 68060 processor support
  - Cyberstorm and Blizzard 2060 SCSI modules [Amiga]
  - All GVP SCSI adapters [except new 68060 card and old Series I]
  - Color on OCS and ECS displays [Amiga]
  - Hard drives partitioned under MS-DOS
  - Parallel port on the Multiface III card [Amiga - serial was
     supported in 1.2.13pl10]
  - ATAPI IDE CD-ROM support

* Hardware support not included in this release but available elsewhere:
  - Floating Point emulation [copyright issues prevent its inclusion
     in the distributed kernel tree]

* In the works:
  - Apollo Domain workstation support
  - Apple Macintosh support
  - Sun 3 support
  - MVME 147 support
  - Debian/m68k (the first real "distribution" for Linux/m68k)
  - Blizzard 1230 SCSI adapter [Amiga]
  - Cirrus Logic-based graphics cards for the Amiga [Picasso, Piccolo, SD64]
  - Atari TOS and AmigaOS emulators


Command line changes
--------------------

The kernel command line has changed somewhat:

* Atari users: the 'atavideo' parameter is now simply 'video', like on the
  Amiga.  See 'Documentation/m68k/kernel-options.txt' for some new parameters
  that are supported.

* If you are booting from a ramdisk, you must now specify the root device
  or else the kernel will not boot.

  Instead of:
    amiboot -r ramdisk-name video=vga70
  Use:
    amiboot -r ramdisk-name video=vga70 root=/dev/ram

* GVP SCSI users shouldn't need the gvp11 parameter any more; the driver now
  auto detects the DMA range that each SCSI controller is capable of using.


How to get upgraded software
----------------------------

If you haven't already upgraded to ELF, the best way is to back up
your user directories, repartition (if you like) and get the
Watchtower-2 filesystems.  These include all the software you need to
upgrade to 2.0.

If you already are running an ELF system, you'll need:

pppd version 2.2.0f or later
sysvinit version 2.60 or later
procps 1.01 or later
modules 2.0.0 or later (only if you are using modules)
NetTools 1.32alpha or later
e2fsprogs 1.06 or later

To compile a kernel, you will need at least GCC version 2.7.2 and
binutils (ld, as, etc.) version 2.7.

In addition, users should upgrade to the latest version of their 
bootstrap (ataboot 1.8 or amiboot 4.0) or Amiga LILO (1.02).

You may need other packages as well depending on your configuration.
Please read 'Documentation/Changes' in the kernel source tree for
details.

		       SCO Files Lawsuit Against IBM

March 7, 2003 - The SCO Group filed legal action against IBM in the State 
Court of Utah for trade secrets misappropriation, tortious interference, 
unfair competition and breach of contract. The complaint alleges that IBM 
made concentrated efforts to improperly destroy the economic value of 
UNIX, particularly UNIX on Intel, to benefit IBM's Linux services 
business. See SCO v IBM.
