  • I cannot speak for the other language versions, but, with the first archive, showing the English set, It is possible to install this in a VMWare virtual machine.

    The archiver of this set used the "savedskf" command to save an image of disk 1. The problem is that savedskf compresses the image and adds some information to the beginning of the file. The disk can be stored byte-for-byte, without compression, by using savedskf with the /a and /d option. Although the remaining disks are in xdf format, they were stored with the "xdfcopy" command, and this saved all the data correctly. VMWare Player 15 (and probably some earlier versions) had no trouble showing the various "bundles" containing the DOS files. Setup didn't complain and everything was unpacked and set up correctly, once disk 1 had been converted into a byte-for-byte copy.

    I saved my copy of PC DOS 7.0 in the same way I mentioned above and I was also able to set it up with VMWare Player successfully. I had no idea it would work, but, it did.

    Even though it will read those xdf disks as straight images, VMWare Player cannot create xdf images.

    Hope this is useful.

  • xdfcopy, which comes with PC-DOS, can save and restore XDF-formatted diskettes.

    The disk images prepared with savedskf /d /a are raw images, such as you save with programs like dskimage/diskmage, or rawrite/rawread. The first proggie that I saw that recriprocated savedskf was makedskf, an OS/2 thing.

    The bundles can be seen with unpack2 /show. IBM had a program dsk2cd which copied the diskette files to a cd so you can run setup from that.

    The sgtk files are a sampler of the DOS 7.1 distro, The consensus is to use the 119 kernel and the 132 stuff elsewise. I'm thinking of using the 132 kernel on the cdrom, because it will time-out to the fixed disk.
