Run USB devices under DOS!

  1. Working with an old PC, I was confronted with a HD that had no bootable partition. It contained data that I wanted to retrieve, without having to move that HD first into another PC.
    My idea was to use a USB key, so I started hunting around for a solution.

    I found this interesting info somewhere on the web, and you can run USB2.0 under DOS!

    This is how a Boot disk is setup to run USB 2.0 from DOS.

    Include in AUTOEXEC.BAT for CD
    MSCDEX.EXE /D:cd1 /L:Z

    Include in CONFIG.SYS for CD and USB2.0 Driver
    DEVICE = himem.sys /testmem:eek:ff ==>>must read: /testmem no space colon no space off <<== silly smilies :blackeye:
    Rem Use whatever CD Driver works for you
    DEVICE = oakcdrom.sys /m:15 /d:cd1

    You can get the Panasonic USBASPI.SYS Driver from the following:
    Scroll down in the new created F2H directory.

    You can get the DI1000DD.SYS "motto hairu" DOS Driver from

    Do NOT use the usbaspi.sys from, it is an older one!

    I'm sure a few of you can now make DOS backups onto external harddrives etc.!

    If it does NOT work for you, DON'T ask ME!

    You could try doing it this way (Disable smilies in text)
    But then you'll have to conted to using text smilies... ;-D

    Aside from that, great find!

    I ran into a similar problem with a computer that didn't boot. I went to and it worked like a charm. I was able to move files to my external iomega USB hard drive.
