The computer does not see any HDD?

Question

Hard disks

Hello. Guys tell me who, what can. Not so long ago I took a Xeon X3470 server processor to Aliexpress, the condition is satisfactory. While the cooler was driving to the processor, I installed it in the motherboard to check its performance. The processor turned out to be working, but the standard cooler did not cool it well. As soon as the cooler arrived, I decided to install it, but before that, clean the motherboard from dust. I've done this more than once or twice. I just wiped it gently with a rag and blew the dust out in some places. I removed the processor and saw that there were a number of bent legs at the attachment point. Armed with a magnifying glass, I straightened them, it was easy. Didn't break anything. Now you can’t even see that they were bent. Put the processor, cooler. And fiasco. The computer does not see any hard drive. Connected to different Sata2 connectors, different drives, but the result is the same. When testing equipment, the following inscriptions appear: No device found, AHCI BIOS not installed (attached photos). Please help me with good advice. And who wants to write nothing to climb, etc., please refrain from such comments. The one who does nothing makes no mistakes. Thank you all in advance.

Answer 1

AHCI BIOS not installed

BIOS reset, for fidelity and reconfigure.
