This is a bootable floppy of PC-DOS 7.1, made with the download available at IBM's website. Created by making a blank floppy image, booting the PC-DOS 2000 Setup floppy from this website in a VM, running sys.com to install the bootloader, deleting the added files, and copying over the PC-DOS 7.1 files.


PCDOS 7.1 Download from IBM'S website, for reference
(PC-DOS 7.1 is found within that file at sgdeploy\sgtk\DOS\)

- This was never fully released and many things do not work. SYS.COM is an example of that, but you can use FORMAT /S or FORMAT32 /S instead.
- A text editor is available at DOS\E.COM.
- FDISK.COM is replaced with FDISK32.COM, which supports FAT32 but is broken on VirtualBox, unfortunately. As an alternative, copy fdisk from FreeDOS, which works fine. Grab that here. all you need is the fdisk.exe in the BIN directory. Ignore the rest.
- When formatting FAT32, use format32.


  • Thanks for the IBM link.
  • To install IBM PC-DOS 7.1, from 2003, on a hard drive:

    1) rawrite disk-image 1 of the pc-dos 2000 installation set to a floppy disk
    2) delete everything from that floppy, and copy the PC-DOS 7.1 files onto it
    3) use some method to identify the first partition of the hard disk as fat32 (it can be a 10GB partition, and it has to be at least 800mb, because 400mb is not good enough for him)
    4) boot the machine from floppy drive
    5) give the commands:
    format32.com c: /q
    xcopy ibmbio.com c:\
    xcopy ibmdos.com c:\
    xcopy command.com c:\
    attrib c:\ibmbio.com +r +s +h
    attrib c:\ibmdos.com +r +s +h

    Now you have bootable IBM DOS on the hard-drive, in a 10GB partition

    mkdir c:\dos
    xcopy *.* c:\dos
    xcopy autoexec.bat c:\
    xcopy config.sys c:\

    adjust config and autoexec according to your taste
    (you can make an IBM DOS bootable usb stick, or a DVD)
