Key to variable attributes:
NV - Nonvolatile. The last value saved by system software or set by console commands is preserved
across system initializations, cold bootstraps, and long power outages.
W - Warm nonvolatile. The last value set by system software is preserved across warm bootstraps
and restarts.
RO - Read-only. The variable cannot be modified by system software or console commands.
Attributes Function

examine or deposit

NV Sets the number of transmissions that are
attempted before the ARP protocol fails. Values
less than 1 cause the protocol to fail immediately.
Default value is 3, which translates to an average
of 12 seconds before failing. Interfaces on busy
networks may need higher values.
NV Supplies the generic filename to be included in a
BOOTP request. The BOOTP server will return
a fully qualified filename for booting. This can be
left empty.
NV Supplies the server name to be included in a
BOOTP request. This can be set to the name of
the server from which the machine is to be booted,
or can be left empty.
NV Sets the number of transmissions that are
attempted before the BOOTP protocol fails. Values
less than 1 cause the protocol to fail immediately.
Default value is 3, which translates to an average
of 12 seconds before failing. Interfaces on busy
