hi,
i wanted to know how to change the MAC id of the machine i`m using.. I know the MAC is permanent n on the ROM, but i wanted to know if there was any way to change it during tht particular session..
also.. if it was possible.. could it be kept changed for sometime...?

Which platform?

I think you just answered your own question. If it's permanently recorded on the ROM, you can't change it in any meaningful fashion.

It might not be so permanent, though. You can get utilities to change the MAC for certain cards.

In Solaris the mac address can be changed with the ifconfig command, and may well be on some other OSes. Shereenmotor's question needs to be answered before dismissing a simple solution.

Would you expect this work on x86 solaris, and/or with non-Sun network cards? I still think my answer fits for all but the weirdest of hardware and software, since the MAC is handled practially at the hardware level.
