    The PS/2 Model 56 LS system units (24X) are shipped with all of the
    standard features of the Model 56 SX with the following exception: no
    DASD devices are installed in this medialess system, but a 16/4MBbps
    Token Ring network card with RIPL (24X) occupies one of three slots. The
    PS/2 Model 56 LS is fully upgradable to the Model 56 SX configurations. "

    Hello,

    It is my first time here!
    Just  to let you know that the 8556 24X is also IML
    I have one. From the factory, it is medialess (without the hard drive
    and floppy). It used a MCA network card or something like that to
    boot and work.
    But, in all of documentation that I read, It should be possible to
    "convert" it to a "regular" PS/2 8556 56SX by adding the floppy and
    the HDD.
    So, I added both floppy (2.88MB) and a SCSI HDD, but I am having a
    lot of trouble to restore (or should I say, create) an IML partition
    on HDD.
    It is perfectly recognised by the tools in the reference disk, it
    formats ok, but no IML restore...
    It suspect that is because the HDD is 2GB in size. But it is the only
    one that I have!

    Do you know if there is a way to make this a working machine?

    By the way, the boot is not possible not even from the floppy drive!
    Because of the model 24X, it says that the boot is only possible from
    the "network" card or from a SCSI drive with ID 6.

    Do you know if the ROM file is swapable by other model that do not
    have this limitation?


    Thanks a lot.

    My guess, just a HD, a mount, and a SCSI cable.
