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``, confirm with ``j`` and - accept the following defaults with or ``j``. -4. If the main screen is displayed again press ``0`` 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!
