Hey guys,

I am a beginner, setting up a hobby OS. I am running into a weird problem to which I can't seem to find the solution. My keyboard interrupt only fires once.

This is what does work:
- timer interrupts are firing, before and after the single kbd irq
- system calls are working as well

To me that is saying I got my IDT setup correctly. I am sending 'end of interrupt' after the keyboard handler returns..

What am I missing here?

Thanks a lot,
Erwin

Are you reading the key from within the handler ?

Nope,

I am only printing a string to see if the handler is firing. And it is doing so only once.

That's most likely your problem. Until you read the key the controller doesn't know that you've serviced the interrupt. Just do an inportb(0x60) from within your ISR and see what happens.

That was it! Thx a lot!
