Error During Post Pc

starting the remainder of the boot process. If the computer passes the POST, the computer may give a single beep (some computers may beep post error codes twice) as it starts and continue to boot. However, if the computer parity circuit failure fails the POST, the computer will either not beep or generate a beep code that tells the user dram refresh failure the source of the problem. If your computer has an irregular POST or a beep code not mentioned below, follow the POST troubleshooting steps to determine the failing hardware component. when should you not wear a wristband ground strap AMI BIOS beep codes Award BIOS beep codes Dell beep codes IBM BIOS beep codes Macintosh startup tones Phoenix BIOS beep codes Motherboard help AMI BIOS beep codes Below are the AMI BIOS Beep codes that can occur.

The POST is the Power-On Self Test that all computers take when they start up. A computer that fails the POST has hardware trouble. Your PC may or may not beep when it starts. http://www.dummies.com/computers/pcs/troubleshoot-post-errors-on-pc-start-up/ If you hear two or more beeps where you heard only one before, the PC may have either a power supply problem or a video system problem. Otherwise, the PC's splash screen is displayed. Any POST errors after that point are displayed on the computer's monitor. What you can do with a POST error depends on the error message. Some error messages are cryptic. One POST error message is 58. Hmmm. Text messages can be just as bad. For example: Resource allocation conflict on motherboard You can choose from two solutions for these puzzling start-up messages: The first solution to try is to enter the PC's Setup program and determine whether the issue can be resolved there. Often, any errors encountered during the POST are flagged in the Setup program, or at least information is provided to help you resolve the issue; for example, to resolve a hardware sharing conflict. The second solution is to contact the manufacturer or your computer dealer to see what's up. If the computer is under warranty and the problem is severe, the manufacturer or dealer has an obligation to fix it. Some PCs sport error feedback on an

If the necessary hardware is detected and found to be operating properly, the computer begins to boot. If the hardware is not beep codes detected or is found not to be operating properly, the BIOS issues an error message which may be text on the display screen and/or a series of coded beeps, depending on the nature of the problem. Since POST runs before the computer's video card is activated, it may not be possible to progress to the display screen. The pattern of beeps may be a variable numbers of short beeps or a error during post mixture of long and short beeps, depending on what type of BIOS is installed. The patterns of beeps contain messages about the nature of the problem detected. For example, if the keyboard is not detected, a particular pattern of beeps will inform you of that fact. An error found in the POST is usually fatal (that is, it causes current program to stop running) and will halt the boot process, since the hardware checked is absolutely essential for the computer's functions.

operate. The progress of the self-test is indicated by a series of POST codes. This chapter explains the BIOS POST testing, provides an alternate method for viewing the codes, describes how to change POST options, and lists the POST codes. This chapter contains the following sections: About POST How BIOS POST Memory Testing Works Redirecting Console Output Changing POST Options POST Codes POST Code LEDs About POST The POST is a systematic check of basic system devices. As the testing progresses, the BIOS displays codes that you can use to interpret the status of your server. The codes appear at the bottom right corner of the system’s VGA screen, after the self-test has progressed far enough to initialize the video monitor. Because the codes might scroll off of the screen too quickly to be read, an alternate method of displaying POST codes is to redirect the output of the console to a serial port (see Redirecting Console Output). You can also see some of the post codes on LEDs inside the front panel of your server node (see POST Code LEDs). How BIOS POST Memory Testing Works The BIOS POST memory testing is performed as follows: 1. The first megabyte of DRAM is tested by the BIOS before the BIOS code is shadowed (that is, copied from ROM to DRAM). 2. Once executing out of DRAM, the BIOS performs a simple memory test (a write/read of every location with the pattern 55aa55aa). Note - This memory test is performed only if Quick Boot is not enabled from the Boot Settings Configuration screen. Enabling Quick Boot causes the BIOS to skip the memory test. See Changing POST Options for more information. 3. The BIOS polls the memory controllers for both correctable and non-correctable memory errors and logs those errors into the SP. 4. The message BMC Responding appears at the end of POST. Redirecting Console Output You can access BIOS POST codes remotely using the web interface or the CLI. To Access BIOS POST Codes Using the Web Interface 1. Open a browser and use the SP’s IP address as the URL. Refer to the Sun Integrated Lights Out Manager 2.0 User’s Guide (820-1188) for information on how to obtain the IP address of the SP. 2. Type a user name and password as follows: User name: root Password: changeme 3. The ILOM SP web interface screen appears. 4. Click the Remote Control tab. 5. Click the Redirection tab. 6. Click the Start Redirection button. The javaRConsole window appears an
