IBM eServer xSeries 335

I would like to use the LinuxBIOS on the IBM eServer xSeries 335. 

Below is the information I was able to capture regarding this server.

I included an ASCII simple motherboard diagram to provide an idea of the integrated circuits location.

The letter leading most of the integrated circuits correspond to their location on the diagram.

I could not identify what of the ICs is the BIOS, so I included most of
them here with a brief description, engraving, IBM label, and links to
resources if available.

Server analyzed:
