Thank you for contacting Intel Customer Support.
My recommendation for this case is to set BIOS to default. Here I will share the Technical Product Specification for your Intel® Server Board S2600IP4, in page 104 you will find all the instruction for this proceedure.
Thank you for your reply.
I have tried as per procedure stated on the manual, but there is still no video output. So I cannot even get into the bios.
Must I remove all the cards from the PCI slots?
EDIt: I removed all the cards and I can finnaly reset bios to default. Thank you
