Description
The BIOS displays an error message or a series of messages on the video
display in the event of hardware or configuration errors. In some cases
the error may be so severe that there is no video output. However, the
error can also be retrieved by means of the service processor. By using
the "sp get port80" command from the service processor, the sp captures
the last 10 POST codes.
For information about retrieving the last port 80 post code using the sp get port80 command, refer to the Sun Fire V20z[TM] Server Management Guide, 817-5249-xx, for details. You can also retrieve the last 10 port 80 post codes using the operator panel. Refer to the Sun Fire V20z Server Management Guide, 817-5249-xx, for more details about using the operator panel menus.
