How the interrupt bios function called?

In a computer, the interrupt BiOS function is typically called when a hardware or software interrupt occurs. This is done through specific interrupt vectors that point to the corresponding interrupt service routines (ISRs) in the BiOS. When an interrupt is triggered, the CPU halts its current operations, saves its state, and jumps to the address of the ISR defined for that specific interrupt. After the ISR completes its task, control is returned to the original program, restoring the CPU's state.
