Hardware interrupts not working (only software) ???
Posted: Sun Mar 21, 2004 12:00 am
Hi,
Ive been working on adding interrupt support to an OS, and have been able to succesfully receive software interrupts (asm("int x")) but when I generate hardware interrupts (by sending a byte to a PCI network card that should generate a hardware interrupt) that handler does not get called.
Is there anything obvious i might be missing (needed for hardware interrupts)?
Thanks,
Martin
