I got the DOS USB support to work sort of
but I can't find the drive letter for the USB
stick.

ELP!!!!!!!

Paul,

You need to use a computer that allows for USB Booting.
That was done around '06 for most systems. If you have
an older PC or laptop, that doesn't have the bios that
allows booting from a USB device, the ASPI manager won't
work.

I checked that Tom. It does indeed have USB support in the
BIOS.

I have been there but I think they want to sell you something.
There is so much free stuff out there that I don't want to take
the risk of buying something and then not having it work.

The one I am focused on most is:
http://www.georgpotthast.de/usb/

Georg provides a wealth of DOS USB program source written in
Power BASIC. Now I just need to get in touch with him.

For some strange reason it crashes the VIA EPIA-M mother board.
Perhaps I need to run it before anything else as it appears
to be a tsr.

Hi Paul,

try to load the usbdisk.sys driver with devload.com. Then it will
display the driver letter assigned.

It will also do this when loaded with config.sys but the following
autoexec.bat may clear it. If you set a pause at the top of the
autoexec.bat you should also be able to see it.

Thanks Georg,

I'll be working on this in the next couple of days.

This is what we are trying to do.

Mother boards are getting so cheap it does not pay
to use a single chip embedded micro processor anymore.
PB is ten times easier to program than C and most PB
instructions execute in less than one microsecond
which is more than enough for the majority of real time
hardware control. Also as you well know DOS allows
direct hardware access so I see a great future for
DOS and PB.

I'll be in touch.

Thanks again.

 Paul,

With the VIA Boards and Power Supply, they are designed
with low cost consumer applications in mind. Operation of 0 to 70C, and
components that meet a 200 ppm reliability rate. While a failure of
200 parts per million seems fantastic, keep in mind that is per component.
So when you get a board with 100 devices on it, each at 200 ppm failure
rate, what it is saying is you have a 20 failures per 1000 systems.
Most will occur in the first few months of operation. The manufacture
accepts this failure rate as part of keeping the cost low.  For the PC
market, this is acceptable and part of doing business.

If you
design in with automotive components, you are now are looking at > 2
ppm being unacceptable, as the goal is 0 ppm field failure rate.
Components (under hood) being rated for -40C to +125C.  Components will
go through burn in, as completed engine modules. Still there are
emergency back up systems (aka 'limp-mode') to get you back to the
dealership for service.

So for a dyno based test system,
20 failures per 1000 is acceptable. If something happens to the board,
you just grab another one.  Using the VIA board for rapid development
is ideal, but I would look at the industrial board vendors and
implementing a back up operation for flight.

OK Tom. Thanks
