Xenix 286 v.1

Hello. I've recently acquired a set of seven Xenix 286 v.1 manuals plus the OS diskettes + the Development system diskettes. These boots, even when I was not sure about its state. I should like to do one copy of them in form of virtual diskettes, in a form that permits use them with Bochs or similar emulator if possible. Problems: * Winimage (soft to do virtual plain copies of disks) can't read the disks. * The dd method under Unix/Linux give me errors. I should need to know the blocksize of the Xenix diskettes and its density (it don't appears in the labels). In appeareance the blocksize needed is 2048, but using this command: dd if=/dev/fd0 of=xenix1_i.dsk bs=2048 conv=noerrors ...returns me one message like this: 3+1 records copied /dev/fd0: error reading... 6+2 records copied ... Suggestions ? Thanks in advance Sergio
