The error messages in the BIOS like 8160,8180 etc. actually were due to the new CPU with the core stepping E0.
Actually, on most Intel server boards using a new CPU with E0 Core Stepping gave these error messages, but this has been fixed with the latest firmware revision BIOS.
Possibly, this may be the same with G0 steppings. In the release notes for the bios, it may mention about the 8180 error.
You can update the firmware using a USB Dos Bootable Memory Stick.
I will advise you to update the bios and bmc firmware to the latest one using a USB Dos Bootable Pen Drive.
