Is it me or must the keyboard interrupt be enabled for the mouse to work? I also found that in bochs if you hit the keys when the mouse is BEINGinstalled, bochs gives a BIOS PANIC, later on, when the reset button is hit. Hmmm, strange stuff. How would one go about fixing these things? IRQ mask? |

afaik, the keyboard handler is not required, as long as no key is pressed. Since the same chip will deliver keyboard and mouse signals to the cpu, if a keystroke is pending but noone reads it, no mouse interrupt can occur. It will be necessary to unmask IRQ2 aswell as mouse IRQ and to acknowledge end-of-interrupt on both master and slave PIC, btw. |
