I am totally shooting in the dark on this, I have no experience with SGI's elan's, but I have changed MAC's on NIC's before to get flexlm working.
On a linux box you would use the command
ifconfig eth0 hw addr ether 00:00:00:00:00:00 or whatever the MAC is that you wanted.
Do you have a similar command on this SGI box?
I hope that helps,
