Probe System for Supported I/O Controllers [Y/N] = Y?
Auto-Initialize of NVRAM Header Enable [Y/N] = Y?
Network PReP-Boot Mode Enable [Y/N] = N?
SCSI Bus Reset on Debugger Startup [Y/N] = N?
Primary SCSI Bus Negotiations Type [A/S/N] = A?
Primary SCSI Data Bus Width [W/N] = N?
Secondary SCSI identifier = 07?
Select the identifier. (Default = 07.)
NVRAM Bootlist (GEV.fw-boot-path) Boot Enable [Y/N] = N?
Note
When enabled, the GEV (Global Environment Variable) boot takes priority
over all other boots, including Autoboot and Network Boot.
Y Accesses will be made to the appropriate system buses (e.g.,
VMEbus, local MPU bus) to determine the presence of supported
controllers. (Default)
N Accesses will not be made to the VMEbus to determine the presence
of supported controllers.
Y NVRAM (PReP partition) header space will be initialized automatically
during board initialization, but only if the PReP partition fails a sanity
check. (Default)
N NVRAM header space will not be initialized automatically during board
initialization.
Y Enable PReP-style network booting (same boot image from a network
interface as from a mass storage device).
N Do not enable PReP-style network booting. (Default)
Y Local SCSI bus is reset on debugger setup.
N Local SCSI bus is not reset on debugger setup. (Default)
A Asynchronous SCSI bus negotiation. (Default)
S Synchronous SCSI bus negotiation.
N None.
W Wide SCSI (16-bit bus).
N Narrow SCSI (8-bit bus). (Default)
Y Give boot priority to devices defined in the fw-boot-path global
environment variable (GEV).
N Do not give boot priority to devices listed in the fw-boot-path GEV.
(Default)
