Debug Card with POST code indicator Series
The primary function of POST card is to latch and display the BIOS POST code on card. During system power on, the M/B perform the POST (Power On Self-Test) routines. The main purpose of these routines are to perform the diagnostics test upon the system component, device detection and chipset initialization etc,. The BIOS will put the POST code in the POST port (for normal M/B is Port 80h, and Compaq is 84h) before each respective task routine is performing.
