I am working on an autonomous stand alone computer system that will regulary
be subjected to a complete power loss with no UPS backup. UPS is not an
option for this application due to numerous constraints. Does Microsoft
make a product that can regularly be "improperly" shut down, and then when
power to the system returns, reliably reboot autonomously?
I am aware that some versions of Windows keep key system files open while
Windows is in active session, and that an improper shutdown could prevent
Windows from properly closeing the files or even worse, corrupt these key
files thereby preventing a safe reliable reboot (when power is restored).
Any experts in the area? Can anyone recommend any solutions? Is their a
"safer" mode for some version of Windows (other than Windows 3.1) that can
reasonably garuntee reliability to reboot? Anybody kow of third party
software that deals specifically with these improper shutdowns caused by
regularly, mostly unknown, power shutdowns? I am not too familiar with
backup applications; does anyone know if these can be made to operate
autonomously in case of a catastrophic file corruption to Windows?
I appreciate any help at all.
you can reply to roberto.s.barr…@boeing.com if you like.
Thanks,

They used to, called MS-DOS… (Why is UPS not an option?)
You can still get IBM PC-DOS 2000 or Caldera DR-DOS. You might also
want to consider using flash memory instead of disk drives.
The software working on the system must be Windows 95 (or better)
compatible.
UPS, unfortunately, is not an option due to the unique environment that this
system will be installed (on an airplane, with TOO MANY constraints to even
begin to discuss).
Can you or anyone explain exactly how the flash memory would be different
than disk drives? Is their a limit to the amount of flash memory that can
be installed on such a system?

Are the power downs controlled or uncontrolled? I have a system
running the original Win95 that gets powered up and then shut down
once each day with a simple mechanical timer switch. The application
that is run each time is a data logger and is always finished before
the timer shuts the computer down. I’ve had no problems with this
setup.

considering that a ***small***ups can be had for $70 i’m not sure
why you’d want to take a chance…
however…windows usually can recover from a power failure…
but i’d hardly say it’s 100% relaible.
about the only "fail safe’ filing system i know of would
be to run linux on the reiser file system.
otherwise NT would be safer than just plain windows.
or…now that i think about it…why not just use a laptop
and run it off the supply?
if the power failed…you’d be covered!
