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.
