firmware for non wireless router DG814

Hi everybody,

I found in my cave a Netgear DG814 router,

I would like to install an open firware like the dd-wrt.

I already have a WRT54G with a dd-wrt firmware and i like all the fonctionality offered with this firmware.

So i would like to change the original firmware of my DG814 to have more fonctionality (such as vlan, ssh and many other)

Do you kinow if it exist for this router ?

And where could i find that?

Thanks for your help, and sorry for my bad english.
