Subject: [ECOS] changing MAC address
Date: Tue, 26 Sep 2006 11:03:00 -0000 [thread overview]
Message-ID: <451908EF.5000902@s3group.com> (raw)
I was able to make 82545GM ethernet functional in Redboot, I am now able
to ping or load file via tftp.
Now I want to make it possible to set MAC address from Redboot, because
in the initial state of hardware - MAC address is filled with 00's.
What is the best way to change MAC address of ethernet controller from
the command line of Redboot?
Intel 82544 driver contains function "set_mac_address" and it is used in
ioctl handler, but:
1) it doesn't write to EEPROM, so it changes MAC address only for a
while - am I right?
2) MAC address is read during the network initialization in RedBoot,
even if I change it from command line, I will need to ask for BOOTP
again, right?
