Is there a way to send keystrokes and mouse signal to a target machine without installing any type of software (even an OS) on the target machine?

I want to do some repair and diagnostics-related (bios-level access) works from outside my workplace.

A partial solution I've figured out: I can log in a machine (let's name it "A") using vnc-like software; this machine will be phisically connected to the target machine ("B"), recieving his video output and sending keystrokes and mouse signal to it via a hardware "thing" that is the target of my question.

I've read of some IPKVM devices, but they're too expensive.

Any homebrew/inexpensive solution? (I like contraptions, also I'm broke).


Solution 1:

Nope​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​. The correct way to do this is:

  1. With a proper IP KVM. These are expensive for a reason: only people with a lot of money need them. That's basically it - supply, demand and target market.
  2. With remote desktop (Windows) or VNC (any OS with a GUI) or SSH (for command-line *nix). You've already mentioned you can't to this because you want this to work above the operating system.
  3. With out-of-band management. For desktop PCs, there is Intel vPro and for servers there's IPMI and their various IP-based KVM's that are built into the OOB management.
