+Not just a footnote of history: EUMEL

+
+The *E*\ xtendable multi *u*\ ser *m*\ icroprocessor *EL*\ AN system (EUMEL) is
+a microkernel-based operating system created in the 1980s. It is sometimes
+refered to as *Liedtke 2* (L2), named after its inventor Jochen Liedtke. L3,
+EUMEL’s successor, is still in use by a few legacy systems as of 2016.
+
+.. contents::
+
+Overview
+--------
+
+EUMEL is different from conventional operating systems in a lot of ways. Some
+of them were neccessary due to hardware constraints at that time and others
+were deliberatly designed this way. EUMEL’s key features are:
+
+Hardware independence
+    The OS has *two* hardware abstraction layers, significantly improving its
+    portability. The first one, Software/Hardware (SHard), provides functions
+    for a concrete machine, such as the Olivietti M20, Amiga ST or IBM PC
+    AT/XT.  EUMEL0 (Urlader), the second layer, implements a virtual machine on
+    top of a specific processor architecture like Z80 or x86. Programs are
+    compiled into bytecode for this machine and thus independent of the actual
+    machine they are running on.
+Single-level store
+    Every object (dataspace) lives in a single, virtual address space. The
+    memory is organized into pages, which can reside in memory or on disk.
+    The operating system transparently moves pages to disk if they have not
+    been in use lately and reads them back as soon as a process requests it
+    ([praxis2]_, p. 82).
+Copy on write
+    Pages are shareable and EUMEL automatically unshares them if one copy is
+    written to.
+Persistence
+    Every file and every task is a dataspace. Since they all reside in the
+    single-level store the machine can powered off and back on again, with all
+    tasks starting from the point where they left off.
+Time-sharing and multi-user
+    A single machine running EUMEL is capable of serving multiple “thin
+    clients” connected via serial lines.
+
+Quick start
+-----------
+
+Fortunately a set of 1.2 MB install floppy disks of EUMEL’s x86 port has been
+preserved. It can be installed in any virtual machine emulating an
+IBM PC. In this example we’re using qemu_. The `first disk`__ is optional and
+contains `install instructions`_ in german language. The `second disk`__ is the
+bootable setup programs. It creates a partition on the harddrive, formats it
+and installs the SHard. `Disk three`__ contains EUMEL0 and base system.
+
+1. Create a 128 MB harddrive: ``qemu-img create  root.img 128M``
+2. Start the setup program: ``qemu-system-i386 -drive
+   file=02_setup.img,if=floppy,format=raw -drive file=root.img,format=raw``
+3. Create a new partition by pressing ``1<return>``, confirm with ``j`` and
+   accept the following defaults with <return> or ``j``.
+4. If the main screen is displayed again press ``0<return>`` and confirm yet
+   again with ``j`` to exit setup. The screen should now read “E N D E”.
+5. Quit qemu and restart it with the third floppy disk. The bootloader
+   complains that “HG ungueltig”.
+6. Press any key followed by ``2`` and a confirmation with ``j``. Reset the
+   machine again.
+7. Now we have to set up the keyboard layout and time. Select “Kanal 1” with
+   ``j``, then press ``n`` until ``pc.1.25`` is displayed and confirm. Disable
+   “Kanal 2” and 15 with ``n`` and decline deleting those channels with ``n``.
+8. Congratulations, a fully functional EUMEL is now running in your virtual
+   machine! For the next steps head over to [praxis1]_.
