## !!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.
