How do I update the BIOS on a very old S2600CP motherboard?

Hi,

I've just been given an ancient, refurbished S2600CP2J motherboard complete with CPUs and RAM and would like to get it fully working again.

The obvious first step is to update the BIOS but the oldest EFI update package available (01.02.003) states that I need to have at least version 01.01.1002 before starting or "the update process may render the system not operatable!"

According to the BIOS screen, my system is currently SE5C600.86B.99.99.x034, build date 08/23/2011.

As I have no wish to kill the system before I get started, is there any way of upgrading it to 01.01.1002 as a minimum?

Thanks.
