Invalid Opcode
Posted: Mon Aug 18, 2003 11:00 pm
Ok I remap the pics setup my IDT put all the exceptions into thier proper places Now heres where the trouble starts I mask the interrupts put the keyboard isr into vector 33(21h)enable the interrupts unmask irq 1 enable the irqs. when i run it it says Invalid Opcode.
A few reasons that it does this are
1.Im enableing the irqs wrong
2.I noticed that when I run the key board irq it shoots off an exception.
3.I coded some thing wrong
4.calling INT 6h
please help
