what is the abbrevation of bios interrupt?

Answer 1

When you say BIOS interrupt, it sounds like you are talking about the the BIOS firmware routines that service an interrupt. Most of the time, the firmware routines written to service an interupt are abreviated as ISR (Interrupt Service Routine).

However, you are more likely asking about the actual hardware interrupts in PCs which are usually called an IRQ (Interrupt ReQuest).
