-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]_.
