Which interrupt vector corresponds to the Non-Maskable Interrupt (NMI)?
Which instruction returns execution from an Interrupt Service Routine (ISR) by popping IP, CS, and FLAGS off the stack?
Interrupt hooking is accomplished by changing the address contained in the interrupt ________.
On IBM PC/AT architecture using dual 8259A PICs, which IRQ line is reserved for cascading the secondary (slave) interrupt controller?
The 8259 Programmable Interrupt Controller uses I/O ports 0x20 and 0x21. Port 0x20 functions as the Control Port, while Port 0x21 serves as the:
The 8088 processor classifies interrupts into how many fundamental primary categories?
