2 * The bios low-memory structure
4 * Some of the variables in here can be used to set parameters that
5 * are stored in NVRAM and will retain their old values the next time
6 * the card is brought up. To use the values stored in NVRAM, the
7 * parameter should be set to "all ones". This tells the firmware to
8 * use the NVRAM value or a suitable default. The value that is used
9 * will be stored back into this structure by the firmware. If the
10 * value of the variable is not "all ones", then that value will be
11 * used and will be stored into NVRAM if it isn't already there.
12 * The variables this applies to are the following:
13 * Variable Set to: Gets default of:
14 * bc_hashexpire -1 300 (5 minutes)
15 * bc_spantree -1 1 (spanning tree on)
16 * bc_ipaddr FF:FF:FF:FF 0 (no SNMP IP address)
17 * bc_ipxnet FF:FF:FF:FF 0 (no SNMP IPX net)
18 * bc_iptrap FF:FF:FF:FF 0 (no SNMP IP trap address)
20 * Some variables MUST have their value set after the firmware
21 * is loaded onto the board, but before the processor is released.
23 * bc_host 0 means no host "port", run as standalone switch.
24 * 1 means run as a switch, with a host port. (normal)
25 * 2 means run as multiple NICs, not as a switch.
26 * -1 means run in diagnostics mode.
