2.3 ETHERNET MAC ADDRESS
PROGRAMMING
2.3.1 BCM4401 Ethernet:
Program the eeprom in engineering
mode
(1) Boot from DOS (Win 98 preferred) and
type b44diag –b44eng
(2) 0:>sromutil –m 001018000001 14e4
8401. MAC address 001018000001,
SVID:14e4 and SID:8401 will be
programmed into eeprom. You can change
to other values if nevessary.
(3) 0:>sromutil –b 0. Disable PXE function
on NIC if PXE binary image is being
integrated into BIOS.
(4) 0:>sromutil –d –feeprom.bin, you will get
your golden eeprom.bin file
(5) Exit to DOS
(6) Re-boot the system
(7) Under engineering mode, customers can
see a list of all commands by typing “help”
after 0:>. In addition, for all parameters,
please type 0:>command ? (for example
0:>secfg ?, and you should get a list of all
parameters associated with that specific
command),
Program the eeprom in manufacture
(1) b44diag -c 0 -e b44kia -f eeprom.bin -m
-T c34 (external loop back cable required).
You
will be prompt to enter MAC address
Or
(2) b44diag -c 0 -e b44kia -fmac macaddr.txt
-T c34 (The program will get the MAC
address from
macaddr.txt)
The contents of macaddr.txt as below will
provide you the MAC address range from
00:10:18:00:00:01 to 00:10:18:00:00:03.
You can modify the macaddr.txt by yourself.
mac_addr_pref = 001018
mac_addr_start = 000001
mac_addr_end = 000003
