Remote Start Method Switch [G/M/B/N] = B?
The Remote Start Method Switch is used when the
MVME1603/MVME1604 is cross-loaded from another VME-based
CPU, to start execution of the cross-loaded program.
Use the Global Control and Status Register (GCSR,
G
located in the VMEchip2 on PowerPC board series
modules) to pass and start execution of the cross-
loaded program.
Use the Multiprocessor Control Register (MPCR) in
M
shared RAM to pass and start execution of the cross-
loaded program.
Use both the GCSR and the MPCR methods to pass
B
and start execution of the cross-loaded program.
(Default)
Do not use any Remote Start Method.

Probe System for Supported I/O Controllers [Y/N] = Y?
Accesses will be made to the appropriate system
Y
buses (e.g., VMEbus, local MPU bus) to determine
the presence of supported controllers. (Default)
Accesses will not be made to the VMEbus to
N
determine the presence of supported controllers.
Auto-Initialize of NVRAM Header Enable [Y/N] = Y?
NVRAM (PReP partition) header space will be
Y
initialized automatically during board initialization.
(Default)
NVRAM header space will not be initialized
N
automatically during board initialization.
Network PReP-Boot Mode Enable [Y/N] = Y?
Enable PReP-style network booting (same boot image
Y
from a network interface as from a mass storage
device). (Default)
Do not enable PReP-style network booting.
