Proliant ML110 G7 - Illegal OpCode Error

Hi.

I have recently decided to rebuild my server and wanted to disable the hardware RAID so I could use software RAID in a Ubuntu installation. So I disabled the embedded B110i controller in the PCI Device configuration menu.

The server rebooted and during POST I received the 'Illegal OpCode error' message with a red background. I've attached a screenshot that shows a similar message.

The following URL describes exactly what I have done and how to repair, I need to find the system maintenance switch to reset the NVRAM and hopefully get back into BIOS setup.

Can anyone tell me where on the motherboard the system maintenance switch is located so that I can jumper position 6 to reset NVRAM.

Thanks in advance
