# Unified PS/2 Driver

Te entire thing is held together inspite 

## !!Assumptions!!
Anyone who works on this should work to keep this list as small as possible/remove as many of these as possible.
- Bit 5 of the response form 0x64 indicates which port the data is coming from. (Not true on all systems)
- A parity or timeout error never occurs.
- PS/2 controller exists.
- Both PS/2 ports being broken doesn't need handling.
- One PS/2 port being broken doesn't need special attention.
- PS/2 controller doesn't need to perform a self-check.
- These DeviceIDs never exist:
    - 0xFFFD
    - 0xFFFE
    - 0xFFFF
    - 0x01xx
    - 0x03xx
    - 0x04xx
- Literally all PS/2 keyboards can be handeled the exact same way. We have the capability for detecting different keyboard types, I just don't bother with it because that would litreally take months to get working.

Supporting mice in the keyboard port and vice versa was a ***bad*** idea, but I do not regret it because it means we're "superior" to real world operating systems.
