Hi, Randy.

What kinds of software are involved here? How old is the Canon (for
example) software, especially the actual device drivers? Have you been to
the Canon website and checked for current WinXP-compatible drivers and
related software for your hardware?

This sounds like something that was designed for pre-95 Windows is trying to
run under WinXP - and knows it. The Win16 Subsystem and Protected Mode are
to allow WinXP to run that old hardware. Config.nt and Autoexec.nt are used
only in WinXP and only to allow WinXP to configure the "DOS" window to
accommodate the old devices.

You could spend a lot of time and effort trying to get your old drivers to
work in WinXP, but you'll be much happier sooner if you get the proper WinXP
drivers. Then COMPLETELY delete all your hardware drivers and related
software. Unplug the hardware and reboot at least once to let WinXP "clear
its head" and forget that such hardware was ever installed. Then plug in
the hardware again and let WinXP detect it on reboot and install the right
support for it.

This is not to say that old hardware won't work in WinXP. Most of it will,
but WinXP is built on the NT architecture, which deals with hardware much
differently than Win9x/ME, which were built on MS-DOS. Win9x/ME drivers
almost certainly will not work in WinXP. Hardware makers know this; they
also know that it is their responsibility to write drivers to support their
hardware. The hardware maker's website is almost always the best source of
drivers and other software to use with WinXP.

If you find (or suspect) that you have deleted some WinXP operating system
files, run the System File Checker. At the Run prompt, type: sfc /scannow
SFC will compare each WinXP file with the "known good" copy held in your
on-disk cache and replace any missing or damaged ones. Have your WinXP
CD-ROM at hand; SFC probably will need to see that.
