Intel® Server Boards SE7320SP2 and SE7525GP2 Error Reporting and Handling 6.2 Error Messages and Error Codes The BIOS indicates the current testing phase during POST by writing a hex code to I/O location 80h. If errors are encountered, error messages or codes will either be displayed to the video screen, or if an error has occurred prior to video initialization, errors will be reported through a series of audio beep codes. The error codes are defined by Intel and whenever possible are backward compatible with error codes used on earlier platforms. Most POST error codes are logged in the system event log. 6.2.1 POST Error Codes and Messages During POST after the video has been initialized, the BIOS outputs the current boot progress codes on the video screen. Progress codes are 32-bit quantities plus optional data. The 32- bit numbers include class, subclass, and operation information. Class and subclass point to the type of the hardware that is being initialized. Operation represents the specific initialization activity. Based on the data bit availability to display the progress code, a progress code can be customized to fit the data width. The higher the data bit, higher the granularity of allowable information. Progress codes may be reported by system BIOS or option ROMs. The response section in the following table is divided into three types: Warning: The message is displayed on screen and the error is logged to the SEL. The system will continue booting with a degraded state. Pause: The message is displayed on the screen and the boot process is paused until the appropriate input is given to either continue the boot process or take corrective action. Halt: The system cannot boot unless the error is corrected. Table 60.
