Ami Bios Boot Codes For Mac
The following are AMI BIOS Beep Codes that can occur. However because of the wide variety of different computer manufacturers with this BIOS the beep codes may vary. Aug 23, 2016 - Trying to install osX onto new ssd but getting 3 beep code on start up. Ram swapped, still getting codes. May 25, 2017 - If you do not see this message, the BIOS boot screen may be hidden. I'm trying to save and exit the BIOS using F4 (MAC OS + MAC terminal. The AMI BIOS Configuration Program (AMIBCP) for Aptio enables customers to modify parameters in a BIOS ROM without rebuilding from source. Developers can modify default values for BIOS setup parameters, modify default boot order in BIOS setup, view and edit sign-on and setup strings, and edit SMBIOS string data.
The Basic Input/Output System is a program that is built into a computer’s motherboard that offers access to the hardware’s setup and configuration. During the initial boot phase, the BIOS is accessed and acts as the controller for processes such as booting the operating system. All Microsoft Windows operating systems must use BIOS to boot the computer. Can Users Access the BIOS? Normally, a novice or casual computer user does not need to access the BIOS. Although this is the case, users still have access as long as the motherboard supports the integrated BIOS.
How to Access the BIOS Turn the computer off. Once the computer is off, turn it back on. Depending on the equipment used in the computer, the computer’s age, and BIOS firmware, do the following after the Power On Self Test: If using a modern computer, the first screen that is shown is the OEM (Original Equipment Manufacturer) logo, which may have instructions on how to access the system’s BIOS. If there is no note, press the “ESC” key to access the boot up information, which will usually explain how to access the BIOS. If this is too fast, press the “pause/break” button on the keyboard to stop or slow down the information. Look for the following information (or something similar) during this process to learn the BIOS key combination:. Press to enter setup. Mac tools online.
Setup:. Enter BIOS by pressing. Press to enter BIOS setup.
Press to access BIOS. Press to access system configuration Note: “” represents the key(s) that must be pressed to access the BIOS setup. If neither of these options gives instructions on how to load into the BIOS, try using the Supplier or Vendor codes. BIOS Supplier Codes The BIOS suppliers have their own built in codes that can be used to access the BIOS setup. There are several BIOS suppliers available but the most common options are: Advanced Logic Research (ALR) – “F2” or “Ctrl+Alt+Esc” Advanced Micro Devices (AMD) – “F1” American Megatrends (AMI) – “Del” Award BIOS – “Del” or “Ctrl+Alt+Esc” Datatech Enterprises (DTK) – “Ctrl+Alt+Esc” Pheonix BIOS – “Ctrl+Alt+Ins” or “Ctrl+Alt+S” These are the usual BIOS access codes for computer systems that an OEM did not build for resale to consumers. If the computer system is made for an OEM to sell to consumers, then the consumer may need to use a separate key combination.
Computer Vendor BIOS Codes Every computer manufacturer wants to customize the BIOS to work with the hardware and software that they provide in the system. They usually generalize the keyboard commands as well to provide faster telecommute based customer support. These are the most common codes that the following vendors use: Acer – “F1”, “F2” or “Ctrl+Alt+Esc” ARI – “Ctrl+Alt+Esc” or “Ctrl+Alt+Del” AST – “Ctrl+Alt+Esc” or “Ctrl+Alt+Del” Compaq – “F10” CompUSA – “Del” Cybermax – “Esc” Dell – “F1”, “F2”, “F3”, “F10”, “F12”, “Del” or “Fn+F1” on laptops. EMachines – “Del” or “F2” Gateway – “F1” or “F2” Hewlett-Packard (HP) – “F1”, “F2” or “Esc” IBM – “F1”, “Ctrl+Alt+Ins” or “Ctrl+Alt+Del” Intel – “Del” Lenovo – “F1”, “F2”, “Ctrl+Alt+F3”, or “Ctrl+Alt+Ins” Micron – “F1”, “F2” or “Del” Packard Bell – “F1”, “F2” or “Del” Seanix – “Del” Sony – “F2”, “F3” or “Del” Toshiba – “F1”, “F2” or “Esc” Note: Some BIOS setups are password protected.
An administrator usually places a password on the system to restrict access to the BIOS through the default BIOS setup screen. The user must contact the administrator in order to access the password. Backdoor Passwords for Protected BIOS Sometimes BIOS suppliers make it possible to bypass the administrator’s password by using a “backdoor” password.
These are default passwords that are built into the BIOS in the event that the old password is forgotten or the current user did not set up the password. Only a few companies’ backdoor passwords are known. The Award BIOS vendors have a variety of backdoor passwords. Try the following: “AWARDSW”, “j262 HLT”, “SER”, “SKYFOX”, “BIOSTAR”, “ALFAROME”, “Lkwpeter”, “j256”, “AWARD?SW”, “LKWPETER”, “syxz”, “ALLy”, “589589”, “589721”, “awkward”, “CONCAT”, “d8on”, “CONDO”, “j64” or “szyx” AMI also has a large list of possible backdoor passwords. Try any of the following: “AMI”, “BIOS”, “PASSWORD”, “HEWITT RAND”, “AMI?SW”, “AMISW”, “LKWPETER”,”A.M.I.,” or “CONDO” The Phoenix BIOS’s backdoor password is “phoenix.” Some off brand manufacturers use similar keys and key combination codes to access the BIOS.
It is important to remember that it is risky for inexperienced users to access the BIOS as they may not know what they are making changes to. Having access to the BIOS setup provides options that are normally inaccessible. Making changes in the BIOS may affect the system during the boot process or while loading hardware on the system. Warning: Changes made in the BIOS may lead to data loss on hard disks or external media connected to the computer.
Only access the BIOS when necessary to minimize the possibility of damaging the system. How to Enter the BIOS on an Apple Mac Unfortunately, Apple Mac computers do not have simple BIOS options. Alternately, they have a similar option called the Extensible Interface (EFI) or Open Firmware that provides access to different options.
The EFI’s button combination is “Cmd(Apple Symbol)+Opt+O+F.” It is done during the start up process. Once the process is complete, there are two chimes or beeps and the EFI greets the user. The Open Firmware Prompt is simple and will display: “ ok” And “ 0” (where the commands/scripts are put in) Although the functionality of the EFI is different from the BIOS’s, it can still function with the Apple Mac’s advanced controls. Only advanced users should change anything through the EFI’s scripting capabilities.
Sun Blade X6275 Server Module Diagnostics Guide C H A P T E R 8 BIOS Power-On Self-Test (POST) Codes The system BIOS provides a basic power-on self-test (POST), during which the BIOS checks the basic devices required for the server to 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 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 ).
You can also see some of the post codes on LEDs inside the front panel of your server node (see ). 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). 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 for more information. The BIOS polls the memory controllers for both correctable and non-correctable memory errors and logs those errors into the SP.
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. Type a user name and password as follows: User name: root Password: changeme 3. The ILOM SP web interface screen appears.
Click the Remote Control tab. Click the Redirection tab. Click the Start Redirection button. The javaRConsole window appears and prompts you for your user name and password again, then the current POST screen appears. To Access BIOS POST Codes Using the CLI 1. Log in to the SP cli with the command ssh root@ and use the command start /SP/console to start the serial console. Changing POST Options These instructions are optional, but you can use them to change the operations that the server performs during POST testing.
To Change the POST Options 1. Initialize the BIOS Setup Utility by pressing the F2 key while the system is performing the power-on self-test (POST). The BIOS Main Menu screen appears. Select the Boot menu. The Boot Settings screen appears. Select Boot Settings Configuration.
The Boot Settings Configuration screen appears. On the Boot Settings Configuration screen, there are several options that you can enable or disable:. Retry Boot List: Automatically retries the boot list when all devices have failed. This option is enabled by default. Quick Boot: This option is enabled by default. The BIOS skips certain tests while booting, such as the extensive memory test. This decreases the time it takes for the system to boot.
Quiet Boot: This option is disabled by default. If you enable this option, the Sun Microsystems logo appears instead of POST codes. Wait for F1 if Error: This option is enabled by default.
The system pauses if an error is found during POST and only resumes when you press the F1 key. On-board IB gPXE Boot First: Sets the on-board infiniband gPXE to always boot first. This option is disabled by default.
POST Codes contains descriptions of each of the POST codes, listed in the same order in which they are generated. These POST codes appear at the bottom right of the BIOS screen as a four-digit string that is a combination of two-digit output from primary I/O port 80 and two-digit output from secondary I/O port 81. In the POST codes listed in, the first two digits are from port 81 and the last two digits are from port 80. You can see some of the POST codes from primary I/O port 80 on LEDs inside the front panel of your server node (see ). The Response column describes the action taken by the system on encountering the corresponding error. The actions are:. Warning or Not an Error - The message appears on the screen.
An error record is logged to the system event log (SEL). The system continues booting with a degraded state. The user might want to replace the unit.
Pause - The message appears on the screen, an error is logged to the SEL, and user input is required to continue. The user can take immediate corrective action or choose to continue booting. Halt - The message appears on the screen, an error is logged to the SEL, and the system cannot boot unless the error is resolved.
The user needs to replace the faulty part and restart the system.

POST Code LEDs Two LEDs inside the front cover of your server node display the same two-digit POST code output from primary I/O port 80 that is shown on the BIOS screen (the right-most two digits on the lower right of the BIOS screen are the POST code from primary I/O port 80). In general, the POST codes change so rapidly that you cannot distinguish individual digits.
Some POST tests take enough time (or pause or stop), however, so that they might be readable if you look at the LEDs through the front panel. Such codes are listed in. TABLE 8-2 POST Codes on the Front Panel LEDs That Might Be Readable Code Meaning 4F Initializing IPMI BT interface. D4 Testing base memory; system might hang if test fails. D5 Copying Boot Block to RAM and transferring control to RAM. 38 Initializing different devices through DIM (Device Initialization Manager).
For example, USB controllers are initialized at this point. 75 Initializing Int-13 and preparing for IPL detection. 78 Initializing IPL devices controlled by BIOS and option ROMs. 85 Displaying errors to the user and getting the user response for error. 87 Executing BIOS setup if needed / requested. Checking boot password if installed. 00 Passing control to OS Loader (typically INT19h).
FF The flash has been updated successfully. Making flash write disabled.
Disabling ATAPI hardware. Restoring CPUID value back into register. Portable lcd monitor for camera. Giving control to F000 ROM at F000:FFF0h. Note - For each cold boot (such as when a blade is re-seated into the chassis), POST testing begins to run and detects system resources for a short while. After just a few POST codes, the node is turned off or restarted depending on the selected state in the BIOS for AC Power Loss (Always On, Always Off, or Last State).
