The board’s self-tests and operating systems require that the real-
time clock be running.
Booting the System
You can configure the MVME167P to boot the operating system in one of
three different ways when bringing up the board: via Autoboot, ROMboot,
or Network Boot.
For details on resetting the MVME167P board through software, refer to
the MVME1X7P Single Board Computers Programmer’s Reference Guide
listed in

Function
GPI0

When set to 1 (high), instructs the debugger to use local static RAM
for its work page (variables, stack, vector tables, etc.).
GPI1

When set to 1 (high), instructs the debugger to use the default
setup/operation parameters in ROM instead of the user
setup/operation parameters in NVRAM. The effect is the same as
pressing the RESET and ABORT switches simultaneously.
This feature can be helpful in the event the user setup is corrupted or
does not meet a sanity check. Refer to the ENV command description
for the Flash/ROM defaults.

Reserved for future use.
GPI3

When set to 0 (low), informs the debugger that it is executing out of
EPROM. When set to 1 (high), informs the debugger that it is
executing from Flash memory (not applicable for the MVME167).
