/*History
When Who What
27 Oct 1994: JRC Written
19 Jan 1998: BJGA Re-written as a transient utility
Functional changes:
* throws errors, rather than writing to stderr
(because we won't be using it from the boot sequence)
* never sets the last-reset-type bit or the checksum byte
* checks for OS version information in file
* checks the checksum stored in the file is valid
