Table 21 POST Error Messages Error code 0271 0280 0281 02F5 02F6 Error message Description/corrective action Check date and time settings BIOS found date or time out of range and reset the RTC. May require setting legal date (1991-2099). Access Setup and check the values in the System Timeand System Datefields of the Main menu. Previous boot incomplete - Default configuration used Initial bootup failed. BIOS automatically loads the default system values, then boot again. Memory size found by POST differed from CMOS The user has added or removed a memory module, thus a memory size that is different from the previous bootup. DMA test failed The DMA control test failed. Software NMI failed An NMI signal is detected and/or a user has pressed the NMI switch. POST beep codes There are several POST routines that issue a POST terminal error and shut down the system if they fail. Before shutting down the system, the terminal-error handler issues a beep code signifying the test point error, writes the error to port 80h, attempts to initialize the video, and writes the error in the upper left corner of the screen (using both mono and color adapters). NOTE: An optional POST code expansion board must be installed in the server for the POST beep codes to be audible. The POST routines cannot display messages when an error occurs if any of the following are present: • The error occurs before the video display is initialized. • The video configuration fails, either there's no graphics card installed or the one installed is faulty. • An external ROM module does not properly checksum to zero. • The system memory cannot be initialized. If an optional POST code expansion board is installed in the server, during these instances, the server emits a buzzing sound followed by a series of audible beeps. An external ROM module can also issue audible errors, usually consisting of one long tone followed by a series of short tones. If you get a blank screen on boot but hear beeps, count the beeps and refer to Table 22 for their corresponding meaning. If you miss the beep code: 1. Turn off the server by pressing the power button for five seconds or more. 2. Restart the server by pressing the power button. 3. Listen for the signal again. The routine derives the beep code from the test point error as follows: 1. The 8-bit error code is broken down to four 2-bit groups (Discard the most significant group if it is 00). 2. Each group is made one-based (1 through 4) by adding 1. System BIOS configuration 32
