Prom Versions
When you are using a PROM version of the 162Bug (e.g., in the case
of the 700/800-series MVME162LX) and you wish to execute the
debugger out of Flash memory rather than from PROM in
subsequent sessions, proceed as follows after the board is up and
running:
1. Install a jumper across J16 pins 1-2 to enable Flash writes.
2. Copy the PROM contents to Flash memory with the PFLASH
3. Remove the jumper from J16 pins 1-2 to disable subsequent
4. Install a jumper at J21 pins 7 and 8. (162Bug always executes
Autoboot
Autoboot is a software routine that is contained in the 162Bug
Flash/PROM to provide an independent mechanism for booting an
operating system. This autoboot routine automatically scans for
the date and time using the following command line
structure:

SET

For example, the following command line starts the real-time
clock and sets the date and time to 10:37 a.m., November 7,
1997:

The board's self-tests and operating systems require that the
real-time clock be running.

whether that location is in PROM or Flash.)
