Network Auto Boot Controller LUN = 00?
Refer to the PPCBug Firmware Package User’s Manual, listed in
Appendix B, Related Documentation
, for a listing of network
controller modules currently supported by PPCBug (Default = $00).
Network Auto Boot Device LUN = 00?
Refer to the PPCBug Firmware Package User’s Manual for a listing
of network controller modules currently supported by PPCBug
(Default = $00).
Network Auto Boot Abort Delay = 5?
The time in seconds that the NETboot sequence 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).
Network Auto Boot Configuration Parameters Offset (NVRAM) =
00001000?
The address where the network interface configuration parameters are
to be saved/retained in NVRAM; these parameters are the necessary
parameters to perform an unattended network boot. A typical offset
might be $1000, but this value is application-specific (Default =
$00001000).
!
Caution
If you use the NIOT debugger command, these parameters need to be
saved somewhere in the offset range $00001000 through $000016F7. The
NIOT parameters do not exceed 128 bytes in size. The setting of this ENV
pointer determines their location. If you have used the same space for your
own program information or commands, they will be overwritten and lost.
You can relocate the network interface configuration parameters in this
space by using the ENV command to change the Network Auto Boot
Configuration Parameters Offset from its default of $00001000 to the
value you need to be clear of your data within NVRAM.
