Protocol (HTTP) response status codes. It includes codes from IETF internet standards, other IETF RFCs, other specifications, intel beep codes and some additional commonly used codes. The first digit of the status code specifies one of five classes of response; an HTTP client must recognise these five classes http://www.computerhope.com/beep.htm at a minimum. The phrases used are the standard wordings, but any human-readable alternative can be provided. Unless otherwise stated, the status code is part of the HTTP/1.1 standard (RFC 7231).[1] The Internet Assigned Numbers Authority (IANA) maintains the official registry of HTTP status codes.[2] Microsoft IIS sometimes uses additional decimal sub-codes to provide more specific information,[3] https://en.wikipedia.org/wiki/List_of_HTTP_status_codes but not all of those are here (note that these sub-codes only appear in the response payload and in documentation; not in the place of an actual HTTP status code).

This class of status code indicates a provisional response, consisting only of the Status-Line and optional headers, and is terminated by an empty line. Since HTTP/1.0 did not define any 1xx status codes, servers must not[note 1] send a 1xx response to an HTTP/1.0 client except under experimental conditions.[4] 100 Continue The server has received the request headers and the client should proceed to send the request body (in the case of a request for which a body needs to be sent; for example, a POST request).

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, https://docs.oracle.com/cd/E19464-01/820-6850-11/POST.html and lists the POST codes. This chapter contains the following sections: About POST How BIOS http://www.dummies.com/programming/certification/power-on-self-test-error-codes-categories-for-the-a-certification-exams/ 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 beep codes 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 post error list 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.
