BDM-610000049 Rev G Chapter 4: Using the cpuModule 57
Main Menu Setup Fields
The following is a list of Main Menu Setup fields.
Power On Self Test (POST) Codes
Each POST Code represents a series of events that take place in a system during the POST. If the POST fails during
a particular POST Code, the system will not boot as expected.
The BIOS uses I/O port 80h to store the active POST Code. A POST Code board is a tool that is used to display
the POST Codes on I/O port 80h. This is usually accomplished with two 7-segment LEDs. Such a board is useful
for debugging a system that is unable to boot.
