I'm able to calculate Albrecht Niekamp's: "The_Miracle" (that uses Multifractal_10) with all the comments in it in the form he posted it on the [Fractint] list serve Oct 23, 2012 -- in VESA video mode 640 x 480 with DOS Fractint v 20.04.4 under WinXP SP3.
The video chip built into the system board of my computer only supports VESA video mode: 640 x 480, and the DOS environment for Fractint is able to allow the calculation of his fractal using that video mode.
However, when I try to use the 640 x 480 (or 4k x 3k) Disk Video modes, I get:
"Insufficient memory to run fractal type 'formula'"
Invoking Disk Video mode apparently allocates some additional memory that "breaks the camel's back" -- despite using the hard drive to write the image to. The version of Multifractal_10 *without* comments has this same problem.
Here's Albrecht's "The Miracle" at 640 X 480: http://www.emarketingiseasy.com/TESTS/FOTD/T_MIRACL.GIF and a zoom into it: http://www.emarketingiseasy.com/TESTS/FOTD/T_MIRAC2.GIF
Question: Any of the developers have any idea of how to get around the Disk Video modes not leaving enough memory for multifractalll-10 to run?
Any debug modes lurking around that might help -- say, specifying the allocation of smaller Disk Video buffers?
Hmmm, IIRC, isn't there a command line option that tells Fractint to use extended memory? IIRC, Windows provides the standard extended memory API hooks to DOS programs, so that might be enough for calculating a disk video image? I wonder how the multi_fractal formula would fair under XFractint (the Linux port of Fractint)? Or the Windows port of Fractint - what was it called? I use XFractint here, should see if the formula works there ... -- David gnome@hawaii.rr.com authenticity, honesty, community http://clanjones.org/david/ http://dancing-treefrog.deviantart.com/
