The driver file chipio.386 generally was installed with various
scanner software or digital camera drivers under Windows 95/98. There
is a mention of how to "comment it out" in the following document with
regards to a KODAK scanner:

     KODAK PhotoDoc Color Scanner

See Appendix B of the above document where you will find out that this
is a driver used to increase the speed of a scanner (or other digital
imaging TWAIN software):

"The chipio.386 driver increases the speed for things to happen, such
as the TWAIN, and if your system has lost functionality such as the
mouse, sound, CD-ROM, or your computer just won't reboot, it could be
caused by a memory conflict between the chipio.386 driver that is
installed with the PhotoDoc Software and a system driver on your hard
drive. It may be loading into memory space that is already occupied,
or possibly it is preventing a system driver from loading into the
memory allocation it requires. You do not need this driver in order to
operate the PhotoDoc scanner, and the scanner maintains full features
and functionality without it."

Unfortunately, you won't be able to turn up anything searching on

The file av360.vxd is trickier. "vxd" files are virtual device drivers
and are often written as custom components for a specific piece of
software. The "av" prefix is standard for "audio visual" and is
PROBABLY some sort of virtual driver for your sound card and video
card. It's likely unique to whatever video and sound cards are on your
system. The "360" indicates to me that it is likely involved with some
sort of 3d video routine, perhaps for a game (I suspect a specific
brand of video card operating in a Windows environment).

The reason it doesn't come up in a search is usually because it isn't
causing any problems, or isn't appearing in an error message. A search
of using the following phrase (in quotes):

     "vxd files"

will turn up a number of archives of vxd files, but the 5 I looked at
didn't have any mention of this one.

I recommend that you do a file search on your system and locate this
file. Then, you can open a text browser such as WordPad, and point it
at that file. If you look inside the file using WordPad it might tell
you what program it is affiliated with. Such information is usually in
plain text at the top or bottom of the file.

You could also search your installation CD's for your system,
especially if they are CD's for your audio, video, scanning, etc.
equipment. It's sort of a brute force solution, but it will likely
give you your answer.

Don't hesitate to ask for clarification should you need it. I'll keep
looking and should I find something specific, I'll post it as a
