6.5.2 Power-On Self Test (POST) Codes
The BIOS indicates the current testing phase to I/O location 80h and to the LCD on the front
panel during POST after the video adapter has been successfully initialized. If a Port-80h card
(Postcard*) is installed, it displays this 2-digit code on a pair of hex display LEDs.

Code Meaning
CP Phoenix* check point POST code
Table 30 contains the POST codes displayed during the boot process. A beep code is a series
of individual beeps on the PC speaker, each of equal length. This table describes the error
conditions associated with each beep code and the corresponding POST checks point code as
seen by a ‘port 80h’ card and LCD. For example, if an error occurs at checkpoint 22h, a beep
