Definition: POST card


(Power On Self Test card) A diagnostic board that is plugged into a PC's peripheral bus in order to display the BIOS's POST codes on a built-in readout. The last POST code displayed before the system locks up identifies the problem area. POST codes are different for each BIOS vendor (but, of course!). See POST code.
