0x60 is the keyboard interupt

many good keyboard routines online...look at some of our links on here.

Mr. Dragonsimoto, 0x60 is the keyboard data port. 0x64 is the keyboard command (write) and status (read) port. More info: see the documents mentioned below.

Regarding to adeelmahmood's question, i'd suggest, he scans and reads throu http://osdev.neopages.net/.

there he will find nifty tips and trickses, explained down to the nitty gritty.

http://osdev.neopages.net/docs/wout_kbd.php is also useful as well as http://osdev.neopages.net/docs/kbd.php. There, Keyboard programming is explained in well structured manner.

stay safe

i have set up my IDT to work with my kernel. i want to use interrupts
for keyboard input. for that i have remapped my IRQ 1 on IRQ 0x21
and for setting up the IDT i have masked my IRQ's so that they could
not fire an interrupt. but after setting my IDT when i try to
unmask them it gets reset with
fetch_raw_descriptor IDT.VALID=0
bochs error. but if dont unmask them it works fine .. for keyboard
i need to unmask IRQ 1 but this is th e problem i m having ..
plz help me out
