Unhandled Interrupt

JoeTheProgrammer · Post by **JoeTheProgrammer** » Wed May 28, 2008 2:35 pm

I am getting "unhandled interrupt: 0xd" when I try to change the system call interrupt number in the tutorial JamesM has written from 0x80 to 0x81. Can anyone point me in the right direction? I am using the same code, except for changing the interrupt number for the system call to 0x81 in syscall.c and syscall.h.

Thanks,
Joseph

Did you add an interrupt handler for interrupt 0x81?

I think so, is it the function called: register_interrupt_handler?

Thanks,

No.

There's an isr you need to add in the interrupt ASM file.
