6 Modifying the Environment

NVRAM Bootlist (GEV.fw-boot-path) Boot at power-up only [Y/N] = N?

YGive boot priority to devices defined in the fw-boot-pathGEV at power-up reset only.

NGive power-up boot priority to devices listed in the fw-boot-pathGEV at any reset. (Default)

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?

YThe Autoboot function is enabled.

NThe Autoboot function is disabled. (Default)

Auto Boot at power-up only [Y/N] = N?

YAutoboot is attempted at power-up reset only.

NAutoboot is attempted at any reset. (Default)

Auto Boot Scan Enable [Y/N] = Y?

YIf Autoboot is enabled, the Autoboot process attempts to boot from devices specified in the scan list (e.g., FDISK/CDROM/TAPE/HDISK). (Default)

NIf Autoboot is enabled, the Autoboot process uses the Controller LUN and Device LUN to boot.

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)

Auto Boot Device LUN

= 00?

Refer to the PPCBug Firmware Package User’s Manual for a listing of disk/tape 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.
