What is BIOS (basic input/output system)? - Computer Notes

WebIn a PC, the BIOS, pre-loaded in ROM on the motherboard, takes control immediately after the CPU is reset, including during power-up, when a hardware reset button is pressed, or when a critical software failure (a triple fault) causes the mainboard circuitry to automatically trigger a hardware reset. WebThese interrupts may come from external to the CPU (eg, timers, devices), or internally (software interrupts/signals), and they have an associated id. The interrupt will pause whatever process is currently executing at a point where it is safe to do so and perform a context switch to the relevant interrupt handler by its id. songs with the name madison in it
