Changing MAC address - Broadcom 4400 NIC card

[William Muriithi]

Hi pals,

I have a situation where the ISP uses MAC address as part of
authentication.  This means that only one PC can ever use this
particular modem. So I have two options:

1] Call the ISP and ask them to swap the MAC address.
2] Change the MAC address of the second host to the MAC address of the
first host.

I would like to attempt the 2rd option first. I. am using Redhat EL 5
on one of the host and have edited
/etc/sysconfig/network-scripts/ifcfg-eth0 to replace the old MAC with
host 1 MAC address. However on restarting the interface, the following
message appears

Device eth0 has a MAC address XX:XX:....., instead of configured
address XX:XX:..... Ignoring

I suspect the kernel is still checking the chipset MAC address before
bring up the interface. Are there tools on RHEL5  that can change the
MAC address of the ethernet  NIC?

Regards,
William
