Pretty much "DOS MODE" is not available at all during boot-up. There is no option like that even if you press F8 or F5 and bring up the advanced boot options menus. M$ idea is that DOS was the cause of most instabilities in older Windows releases so they "fixed" that by doing away with it. As for how well that worked out, that's a matter of how you use your computer, for a lot of folks it didn't help, for some it did. Older DOS based programs like FRACTINT are just going to be out and out frozen out because everything that they needed to work was so very DOS-centric. As for the Windows versions of Fractint I've had no luck what-so-ever with them. They just won't run right for me. Maybe in future releases that'll change but so far no dice. -----Original Message-----

Tim,

...

...under Windows 7 in XP compatibility mode, if I set "tools->disable integration features", running the DOS fractint shows nothing, but after pressing F3, a fractal is indeed generated.

I can get both images & text to appear in Win XP's DOS mode, but apparently my video card only does one VESA graphics mode, 640 x 480 -- as well as the needed text mode. I then set "High" Idle Sensitivity on the shortcut and use <alt>Enter to switch back and forth between full screen and windowed Fractint.

I can only make this switch without disrupting Fractint if the program is in text mode, so I can't leave an image calculating in a window while I (say) read email. To get around this, I first "locate" my fractal in my one working video mode & then calculate it in Disk Video mode -- which keeps Fractint in text mode.

Fractint's intense CPU usage leaves a very sluggish computer, though.

...

Hard to use, though, without any text screens showing. I hope the problem is not your graphics card not implementing the needed DOS text mode...

Can you run another text only DOS program to see if your problem of no DOS Fractint text is reproducible in another DOS program?

Can Chkdsk still be run at boot time in DOS mode in Win7 or is "DOS mode" gone -- and not available to test your graphics card's being able to enter a DOS text mode?

BIOS Setup routines have, in the past at least, likely used DOS text mode. What are they using these days?

Are there docs available describing the video modes available on your graphics card?

It's my understanding that it's primarily the video card/chip companies no longer implementing many DOS modes in graphics cards being the problem with getting DOS Fractint to run on recent computers...

...

Hmmm, might be possible to run a PAR file from the command line. That sounds like a possibly workable scenario.

...

Of course Rich's windows version does work nunder Windows 7 (albeit without mouse support). I've found that I can move the cursor around (when in Palette Editing mode: "e") using <ctrl> and arrow keys, but this really isn't as convenient as using a mouse.

Rich, Tim, When using Rich's Fractint for Windows beta 5 to render Jim's FOTD, I have found a couple of items that give me a problem, only one of which I can overcome.

The X dimension of every fractal calculated from Jim's parameter files is stretched too wide. By trial & error I found that reducing the X Magnification Factor by a factor of 0.75 (z, F6), can reproduce the aspect ratio of the same image calculated by DOS Fractint.

Another problem (that I've *not* been able to overcome) is that the program always creates a single color image for any fractal that uses the MandelbrotBC3 formula. Amazingly, the almost identical MandelbrotBC1 and MandelbrotBC2 formulas produce correct images. This fact may be of some help in locating the source of the problem.

The examples of Jim's FOTD that I used to discover this behavior are listed below my signature.

Also, images created using the rotation of the zoom box behave in a different way than the DOS zoom box. This may, in part at least, be related to the different X Magnification Factor factor of 0.75 .

Jim's FOTD for Dec. 4th, 2010 (a "native" Fractint Julia fractal) rendered in Fractint for Windows beta 5 also doesn't quite match the one created by DOS Fractint. I pasted a copy of Jim's PAR file for this fractal at the end of this email.

The formula behind the image is a very simple one -- Z^2.003+C, made more interesting by displaying the part of the infinite fractal that lies 1029 turns up the logarithmic hyperspiral. At this lofty height, the parent fractal resembles the Mandelbrot set rotated 180 degrees, so that the split along the negative X-axis cuts the East Valley area, which at the same time begins to broaden.

Today's harmless little scene appears in the Z^sqrt(sqrt(2))+C Mandeloid as it appears 59 levels up the complex logarithmic ladder. (The logarithmic ladder is explained below.) . . . The 'complex logarithmic ladder' is a phrase I invented. I sometimes refer to the same thing by the name 'logarithmic hyperspiral'. Neither phrase will be found on the internet. I invented the phrases because the complex logarithmic function is multi-valued, and can have an infinity of solutions. Each solution gives a unique four-dimensional Julibrot fractal, complete with both Mandelbrot and Julia slices. In my mind, I simply stacked these four-dimensional fractals onto one another until they formed a single many-layered hyper-object of 5 or so dimensions. It is the stack of all the Julibrot fractals possible to create with a single exponent of Z that I call the logarithmic ladder. Today's parent fractal for example exists on the 59th level of this ladder. The ladder could perhaps be more conveniently thought of as the 59th floor of an infinitely tall skyscraper.

In the MandelbrotBC2 formula, the p1 parameter determines the exponent of Z, while the p2 parameter determines the level of the ladder we wish to explore.

Today's image is a scene on the infinitely fractured main negative stem of the Z^(2.001)+C Mandeloid as it appears at ground level of the logarithmic ladder when no function is applied. The precise location is in the East Valley of the large minibrot on this fractured stem.

For what it's worth (not much other than as a curious fact), under Windows 7 in XP compatability mode, if I set "tools->disable integration features", running the DOS fractint shows nothing, but after pressing F3, a fractal is indeed generated. Hard to use, though, without any text screens showing. Hmmm, might be possible to run a PAR file from the command line.

Of course Rich's windows version does work nunder Windows 7 (albeit without mouse support).

I have done very little with virtual machines. Just for my education I might try installing DOS or Windows XP itself under Virtual PC, or maybe VirtualBox.

(later)

Guess what, I tried Winfract (Jonathan's 16 bit version), and it does work, apparently just fine, on Windows 7 64 bit in XP compatability mode! This time the "enable integration features" setting didn't matter. Even the mouse works ...
