Does anyone have a copy of firmware v7.00.1 for the Linksys WRT54G router?

That's the version my router runs.

I am intending to upgrade it to the current version (v7.00.8), but unfortunately the Cisco site no longer makes older versions available, and I am hesitant to perform a firmware upgrade without having a copy of the firmware my router presently runs, just in case I need to roll back.

I've looked all over the Web for my version of the firmware, and cannot find it.

I just received a call from Cisco in the US, and unfortunately it is no longer permitted to make those old versions available.

If anyone has it, I'd be very grateful for a copy.
