7i77 firmware

Hi,

I recently updated a old pc, to wheezy, and 2.7.11, but I'm now getting a error saying the 7i77 firmware is old/outdated. I solved a problem like this before, But I can't remember and also can't find the command to update the 7i77 firmware.
I know I must set W4 & W12 to setup mode, but then, what firmware is correct? And what command do I use?

freeby.mesanet.com/software/parallel/sserial.tgz
has the new firmware and the scripts plus a readme file of instructions

Thank You very much Peter.
