Abstract: A device (10) for user replacement of an inoperable, first boot loader program includes a boot memory (20) including the first boot loader program beginning at a first address, a PCMCIA card (15) including a second boot loader program beginning at a second memory address, and a selector switch (12). Selector switch (12) receives the user selection of one of the first boot loader program and the second boot loader program, and generates a selection signal corresponding to the user selected boot loader program. Combinational logic (21) receiving the selection signal, enables the selected boot loader program and disabling the other boot loader program.
