I recently purchased a poweredge t610 second hand, and it's currently loaded with Ubuntu 22.04 LTS Server, and I have not been able to access bios. On startup the dell splash screen is not appearing and I'm not getting any bios prompt, trying to click f11 while it is booting just prevents it from booting into the OS, until I hit enter. I'm not sure if I'm doing something wrong trying to access BIOS, but I've been trying everything I can think of without much success. I am trying to access BIOS, so that I can get the process of installing Proxmox started.
