Abstract: A system includes a host and a display. The host includes a programmable logic device (PIP), a baseboard management controller (BMC) and a switch. The PLD performs a power-on procedure based on a power-on sequence code, generates variable character information in the power-on procedure, and fills the variable character information into a variable field in a preset log text file to result in an updated log text file. When it is determined that the power-on procedure is not normally completed, the PLD controls the switch to switch to a debug mode, and transmits a video signal containing debug information corresponding to the updated log text file to the switch so that the video signal is outputted to the display.
