NVRAM Bootlist (GEV.fw-boot-path) Boot at power-up only [Y/N] = N?
NVRAM Bootlist (GEV.fw-boot-path) Boot Abort Delay = 5?
The time in seconds that a boot from the NVRAM boot list will delay before
starting the boot. The purpose for the delay is to allow you the option of
stopping the boot by use of the
BREAK key. The time value is from 0-255
seconds. (Default = 5 seconds)
Auto Boot Enable [Y/N] = N?
Auto Boot at power-up only [Y/N] = N?
Auto Boot Scan Enable [Y/N] = Y?
Auto Boot Scan Device Type List = FDISK/CDROM/TAPE/HDISK?
This is the listing of boot devices displayed if the Autoboot Scan option is
enabled. If you modify the list, follow the format shown above (uppercase
letters, using forward slash as separator).
Auto Boot Controller LUN = 00?
Refer to the PPCBug Firmware Package User’s Manual for a listing of disk/tape
controller modules currently supported by PPCBug. (Default = $00)

devices currently supported by PPCBug.
(Default = $00)
Auto Boot Partition Number = 00?
Which disk “partition” is to be booted, as set forth in the specification pertaining
to the PowerPC Reference Platform (PRP) architecture. If set to zero, the
firmware will search the partitions in order (1, 2, 3, 4) until it finds the first
“bootable” partition. That is then the partition that will be booted. Other
acceptable values are 1, 2, 3, or 4. In these four cases, the partition specified
will be booted without searching.
Y Give boot priority to devices defined in the fw-boot-path GEV at
power-up reset only.
N Give power-up boot priority to devices listed in the fw-boot-path GEV
at any reset. (Default)
Y The Autoboot function is enabled.
N The Autoboot function is disabled. (Default)
Y Autoboot is attempted at power-up reset only.
N Autoboot is attempted at any reset. (Default)
Y If Autoboot is enabled, the Autoboot process attempts to boot from
devices specified in the scan list (e.g.,
FDISK/CDROM/TAPE/HDISK). (Default)
N If Autoboot is enabled, the Autoboot process uses the Controller
LUN and Device LUN to boot.
