The P80DB1L card allows you to display motherboard debug information, even if there’s no such display on your motherboard. It uses an Altera/Intel Max V CPLD which decodes data sent to port 80 on the LPC bus, which is accessible on many motherboards using the TPM header. Newer SPI TPM headers are not compatible. Pinouts of the card, cables and standard headers are available below.
