The following assembler program allows you to redirect an interrupt vector. When the bit boot is set, the interrupt function irq (which is part of your boot loader) is executed. When a boot is clear, the interrupt vector is redirected to 0x20020. All other interrupt vectors are redirected to a vector table at address 0x20000. paul vincent o\u0027callaghanpaul vi principal search
