The forum could be offline for 30-60 minutes in the very near future for maintenance (said 3pm Pacific). I was behind on getting this notice. I do apologize.

    To Hans Ruegg: See the Allen's first post in this thread. Go to http://www.drdos.com/

    You will find their "free" download of version 7.03 floppy images.
    There is probably some sort of licensing agreement on one of the
    floppys. IMHO drdos is much better than Ms-Dos 6.22. But I doubt
    it will run with any 32 bit version of Windows.

    Just curious: Does anybody know what the license conditions
    for DR-DOS are? There was once an information that Lineo
    distributed it as free software, but now it seems to be
    commercial again?

    Hey .. this was meant to be funny ...

    I write DOS apps in PB3.5 for datarecovery. I NEED DOS .... currently using FreeDos, soon my DOS based apps will ship with PTSDOS which is a bit more stable.

    I love DOS!

    Bah Humbug, Joep!

    I've been developing powerbasic (and turbobasic) code for ten years
    now. A lot of it is running on Megatel single-board PC's (4 inches
    square by 1/2 " thick), 386 and 486 class machines with as little as 2 MB
    RAM and 1 MB flash disk (not even as big as a floppy disk...). They run
    DOS 6.2, and a 200K powerbasic executable. No keyboard, no video, no mouse;
    all communication is through the serial port. Show me where the Linux
    or Windows install disks are for a machine like that.

    These computers control and monitor mechanisms on astronomical instruments
    mounted to telescopes. This hardware and software runs continuously for months
    at a time without power cycling, reboots or restarts. The only time they are
    shut down is when lightning storms are threatening. Never had a crash yet,
    which is important when the user is literally a non-technical person with
    minimal or non-existant onsite support on a mountain top 8000 miles away.

    Would I give up my bullet-proof DOS and Powerbasic for something "better"? Nope, not
    until you can pry those floppies from my cold, dead hands....

    As well as DR-DOS being a yet viable alternate for DOS operations,
    you might note that IBM's version of DOS is still very much alive
    and supported. This is all recall, not supported by the URL facts
    here .. but memory says that it was updated to Y2K compliance, in
    whatever format that might be at the same time OS/2 was moved forward
    to Y2K compliance. The DOS-VDM operations in OS/2 were synchronized
    with that. Further, recall says that in a release surrounding the
    question of support for their separate version of DOS, support will
    continue for it. And unless my memory is wrong, the admitted number
    of supported sites world-wide that they were committed to supporting
    was the round number 16,000,000 installs.



    The issue about a supportable and on-going DOS that will boot and run
    things from floppy drives is still quite important in some oblique
    ways, per what I've seen. For example, at least as a couple years ago,
    the entire flash BIOS updates for the Adaptec 2940UW and 2940U2W SCSI
    hard disk controller cards required a dedicated DOS floppy for boot.
    Not only that you have to copy the update flash program to it, but
    the upgrade program also requires etither EMM386, or QEMM whatever,
    or some form of upper memory enablement to even run!

    And much as I might like OS/2 ... grin... you can't make a bootable
    DOS diskette from it for such purposes.. even though a far better
    DOS than DOS exists within it. Wry smiley.

    The second Commandment is not quit true!
    Some sort of multitasking was included in MS-DOS 5.0.
    In DOSSHELL. But nobody used DOSSHELL so Microsoft removed
    it in later versions.
    Pesonally I have used PC-DOS 7.0 from IBM since 1999.
    Later it was renamed DOS2000. Among other things it includes
    Stacker for disk-compression. An exellent program.

    Ah, funny But it looks like many of these Commandments apply to MS-DOS, not to DOS. And maybe the #10 was erroneously taken from a Windows thing ?
    Mmm, i think my customer who has to uninterruptedly run unattended number-crunching apps wouldn' t frame that and hang it to the wall Unless i was suggesting him to port all code to Linux of course... but i'm not ready for this yet

    The DOS 10 Commandments

    1.) I am thy DOS, thou shall have no OS before me, unless Bill Gates gets
    a cut of the profits therefrom.

    2.) Thy DOS is a character based, single user, single tasking, standalone
    operating system. Thou shall not attempt to make DOS network, multitask,
    or display a graphical user interface, for that would be a gross hack.

    3.) Thy hard disk shall never have more than 1024 sectors. You don't need
    that much space anyway.

    4.) Thy application program and data shall all fit in 640K of RAM. After
    all, it's ten times what you had on a CP/M machine. Keep holy
    this 640K of RAM, and clutter it not with device drivers, memory
    managers, or other things that might make thy computer useful.

    5.) Thou shall use the one true slash character to separate thy directory
    path. Thou shall learn and love this character, even though it appears
    on no typewriter keyboard, and is unfamiliar. Standardization on where
    that character is located on a computer keyboard is right out.

    6.) Thou shall edit and shuffle the sacred lines of CONFIG.SYS and
    AUTOEXEC.BAT until DOS functions adequately for the likes of you. Giving
    up in disgust is not allowed.

    7.) Know in thy heart that DOS shall always maintain backward
    compatibility to the holy 2.0 version, blindly ignoring opportunities to
    become compatible with things created in the latter half of this
    century. But you can still run WordStar 1.0

    8.) Improve thy memory, for thou shall be required to remember that
    JD031792.LTR is the letter that you wrote to Jane Doe three years ago
    regarding the tax deductible contribution that you made to her
    organization. The IRS Auditor shall be impressed by thy memory as he
    stands over you demanding proof.

    9.) Pick carefully the names of thy directories, for renaming them shall
    be mighty difficult. While you're at it, don't try to relocate
    branches of the directory tree, either.

    10.) Learn well the Vulcan Nerve Pinch (ctrl-alt-del) for it shall be thy
    saviour on many an occasion. Believe in thy heart that everyone
    reboots their OS to solve problems that shouldn't occur in the first place.

    I am glad to see that DOS lives!!!

    I have an old Compaq I use as strictly a "DOS machine". It has DRDOS
    7.03 as the primary OS, along with 4DOS (by JPSoft - everything Micro$oft
    DO$ could have been). It's only purpose in life is to provide a home for
    PB/DOS 3.5 and Vision. There is a 700MHZ partition that holds a very
    GUI - lite version of Linux Redhat as well, patiently waiting for the day
    it will host PB for Linux!

    started a topic DRDOS Lives

    DRDOS Lives

    For those that are interested in DOS, DRDOS has been acquired by
    DeviceLogics. It looks like they are going to be releasing a new
    version of the operating system. They can be reached by the
    following:

    I am glad to see that DOS lives!!!
