Versions of DOS to run Fractint under
=========================================
Kevin,
Fractint doesn't need to be on the same floppy
that boots DOS. Put Fractint 20.0 and its fractint.cfg
on a separate 1.4MB floppy.
One would want to boot DOS from a floppy and read
Fractint from a 2nd floppy
only for the purpose of establishing whether you
are having problems with you video hardware or
just with the XP video drivers.
I also recommend putting textsafe=save into a
SSTOOLS.INI file on the same floppy as Fractint
since it is the most conservative and thus most
likely to work method of insuring nondestructive
text and video image swapping.
If you do not need the version of DOS that you
boot to be able to read your hard drive (as in
the scenario above)
any relatively recent version of DOS should do.
(Say, 4.0 on thru the DOSes that come with Win 9X.)
If you want DOS to be able to read a FAT32
partition on your hard drive (as in the scenario
that Tim Wegner described and I copied below)
you need the DOS
from Win98 or a DOS specially written to have
this capability. I am not certain, but I assume that
Win ME has a DOS that can read FAT32. The
DOS from Win95 and earlier DOSes cannot read
FAT32.
And Windows NT and 2000 have no DOS.
An afterthought - laptops often have non-standard
video hardware so one can expect to find a
few more problems and fewer working compatible
video modes than found in the video hardware
in desktops.
For a good overview of Fractint and video
hardware see Noel Giffin's:
http://spanky.triumf.ca/www/fractint/hardware_modes.html
You will probably want to run Makefcfg
(that comes with fractint) from
DOS (put it on the floppy with Fractint or on a
separate floppy) to have it create a fractint.cfg
file compatible with your video hardware.
"Makefcfg 1.0 -- A Fractint video utility by
The Stone Soup Group"
"Makefcfg reads your VESA Video BIOS and
writes a Fractint fractint.cfg file with VESA
video modes set up."
Re Tim's recommendation to "Make a FAT32
partition for fractint"... I recommend that you
use Partition Commander or Partition Magic
to do this. DOS's FDISK will delete Win XP if
you attempt to create a FAT32 partition on
your existing hard drive.

On my Gateway desktop machine running
Win98 to safely go between a running
copy of Fractint and back to the Windows desktop I:
- Put textsafe=save into sstools.ini
- View any text screen in Fractint (say, hit Tab
while calculating an image)
- Type the key combination <Alt>Enter to
change the fullscreen text to a window.
I can then use my Windows normally.
- Click on the window title bar to select the
window (rather than in its interior) when you
want to go back to Fractint.
- Type the key combination <Alt>Enter to
change the windowed text to full screen.
- Hit Tab again and you are back to
calculating your image.
Note that Fractint does not contine
calculating your image while you are
viewing the Tab or X screens.
I do not know if this method will work under
Win XP I but offer it as something that
works consistantly in Win98 for me and
might possibly be of help in Win XP.
If I don't adhere strictly to the above, the
video in Fractint is corrupted or the
Fractint task is terminated by Win98.
<======<< <======<< <======<<
Will an XP user please let me know if the
<Alt>Enter key combination is still bound
to the action of switching between a
windowed and full screen **DOS** text
window?
<======<< <======<< <======<<
The only way I have been able to
figure out how to have Fractint
continue calculating an image while
I am using my machine for other windowed
tasks is to use a Disk Video mode. After
starting a fractal calculation in Disk Video
mode I then use <Alt>Enter to make the text
mode Disk Video window of Fractint a
window on my desktop. I move the window
to where I can see the status message:
"Image has been completed" when is done.
I have had a dozen copies of Fractint
calculating Disk Video images at the
same time successfully with no problems
other than a decrease in Windows'
responsiveness.

Ok, my floppy is external USB, and apparently not bootable, I got freeDos, it worked from CD, but couldn't see the floppy either. I added fractint to the CD, and it stopped booting. :( I was thinking I could at least test with the CD booted Dos, using the ramdisk A: that appears to be loaded by freeDos. But now I just get straight into windows, I must have somehow broken the bootable CD by adding files to it. I'm going to try to update Roxio, since it keeps thinking my drive is busy, and see if the other software I used could be the problem, but it's looking like the only way I'm going to get anything even tested is by getting a Dos or linux partition.

You're using Roxio under WindowsXP? Not a good combo - bugs that can corrupt data CDs. Instead of updating Roxio, buy Nero Burning ROM.

Download one of the many Linux CDs that provide live file systems (boot and run off of the CD). My favorite is Knoppix <http://www.knopper.net/knoppix/index- en.html>, finds and supports all kinds of weird peripherals, I'm sure it could find your USB floppy drive. Then you could try using BOCHS or DOSEMU to run DOS and Fractint. Or you could download XFractint and try that under Linux instead. Of course, that might not help you identify the cause of the problem under Windows ... David gnome@hawaii.rr.com

Using it since it came with the laptop, CDBurnerXP Pro worked though, was updating roxio because it wasn't working. the error has something to do with 'device in use by "(null)"'

I actually have a knoppix CD I burned a couple months ago, don't remember if I tried it and it didn't work, or what though. Hmm I can't seem to open any of the files on it, don't know if that's normal or not. I'll have to test the knoppix cd and see if it works before I start anything else.

that didn't work, even at runlevel 2 all I got was a black screen. I'll have to get a newer version, mine was 3.1 beta from august. Well not that out of date, they are only up to 3.2 now I see, but it'll take me a while to download it. Kevin
