The easiest would be to install the devkit. If that is not an option, you can copy the code from https://github.com/CosmosOS/Cosmos/blob/6638f8e357951e930d78f99e1daa3f8e2a789f9b/source/Cosmos.HAL2/PS2Keyboard.cs#L93 and create your own local version of the method....

Can you post your code?

Change the namespace of your version, so that you can address it.

change line 8 from `namespace Cosmos.HAL` to `namespace keyboardTest1`

add `using Cosmos.HAL;` at the beginning of the file.

What's the result when you let it run?

What is the nasm error?

Thanks for your work! Can you please open a pull request so we can discuss it further and merge it when its ready?
