Dell Precision t3500 not recognizing keyboard in BIOS

[Brainstormz123]

Hello, I have a Dell precesion T3500 and am trying to get it working and install an OS on it. It boots fine and gets to a part in the boot sequence where it says “Strike the F1 key to continue, F2 to run the setup utility Press F5 to run onboard diagnostics”

I am unable but to use the keyboard to press any of these function keys. I have tried here separate keyboards, a PS/2 to usb converter, using the onboard USB, and even disconnecting the hard drives. I have tried 3 different GPUs and 2 hard drives. I have a spare motherboard but I think that one is water damaged. On the front, I have the POST light of 1, 2, and 3. Resetting CMOS and reseating/replacing the battery did nothing. I have also tried two cpus and none of this gets rid of that error. Can you suggest what I can do in order to install windows or at least get a keyboard to work in the BIOS?

Try a normal PS/2 keyboard.
