Once your Mac boots from the ASD disk or USB stick, you will see the ASD main menu on the screen. This menu lets you choose between two modes of running ASD: ASD (OF) and ASD (OS).
How to choose between ASD (OF) and ASD (OS) modes
ASD (OF) and ASD (OS) are two different modes of running ASD that use different environments and test routines. Here is a brief explanation of each mode:
ASD (OF) stands for Apple Service Diagnostic Open Firmware. This mode runs ASD in a low-level environment that bypasses the Mac's operating system and uses the Open Firmware interface. This mode can test the basic hardware components of your Mac, such as CPU, memory, logic board, power supply, battery, sensors, fans, etc. This mode is faster and more reliable than ASD (OS), but it has fewer test routines and less graphical interface.
ASD (OS) stands for Apple Service Diagnostic Operating System. This mode runs ASD in a high-level environment that uses the Mac's operating system and its drivers. This mode can test the advanced hardware components of your Mac, such as optical drive, hard drive, Ethernet, Bluetooth, AirPort, USB, FireWire, audio, video, keyboard, mouse, trackpad, display, camera, etc. This mode is slower and less reliable than ASD (OF), but it has more test routines and more graphical interface.
To choose between ASD (OF) and ASD (OS) modes, you need to do the following:
From the ASD main menu, use the arrow keys to select either ASD (OF) or ASD (OS) and press Enter.
If you choose ASD (OF), your Mac will reboot and load the Open Firmware interface. You will see a message that says "Loading Apple Service Diagnostic..." on the screen. Wait for a few seconds until you see the ASD (OF) main menu on the screen.
If you choose ASD (OS), your Mac will reboot and load the Mac OS X interface. You will see a message that says "Starting up..." on the screen. Wait for a few minutes until you see the ASD (OS) main menu on the screen.
How to run the test routines and view the results
Once you see the ASD main menu on the screen, you can run the test routines and view the results. The test routines are divided into two categories: Quick Tests and Extended Tests. Quick Tests are faster and less thorough than Extended Tests. Extended Tests are slower and more thorough than Quick Tests. You can choose to run either Quick Tests or Extended Tests or both depending on your needs and preferences.
To run the test routines and view the results, you need to do the following:
From the ASD main menu, use the arrow keys to select either Quick Tests or Extended Tests or both and press Enter.
If you choose Quick Tests, your Mac will start running a series of short tests on your Mac's hardware components. You will see a progress bar and a status message on the screen. Wait for a few minutes until all the tests are completed.
If you choose Extended Tests, your Mac will start running a series of long tests on your Mac's hardware components. You will see a progress bar and a status message on the screen. Wait for several minutes or hours until all the tests are completed.
If you choose both Quick Tests and Extended Tests, your Mac will first run Quick Tests followed by Extended Tests on your Mac's hardware components. You will see a progress bar and a status message on the screen. Wait for several minutes or hours until all the tests are completed.
After the tests are completed, you will see a summary of the test results on the screen. You will see a green check mark next to each test that passed, a red X mark next to each test that failed, and a yellow exclamation mark next to each test that was skipped or aborted. You will also see the total number of tests, the number of tests that passed, failed, skipped, or aborted, and the overall test status.
To view more details about the test results, you can press the Tab key on your keyboard to switch between different views. You can see the test name, description, duration, result, error code, symptom code, and additional information for each test. You can also see the system information, such as model, serial number, firmware version, operating system version, etc. for your Mac.
To save the test results to a file, you can press the S key on your keyboard. This will create a file named ASDResults.txt on the ASD disk or USB stick. You can open this file with any text editor or word processor to view or print the test results later.
To quit ASD and restart your Mac, you can press the Q key on your keyboard. This will exit ASD and reboot your Mac normally.
How to Interpret and Troubleshoot ASD 258 PPC Results
After running ASD 258 PPC on your Mac, you might have some questions about the test results and how to troubleshoot them. Here are some tips and guidelines to help you interpret and troubleshoot ASD 258 PPC results.
What are the different types of test results and what do they mean?
There are four types of test results that ASD 258 PPC can generate: pass, fail, skip, and abort. Here is what each type means:
Pass: This means that the test was completed successfully and no hardware problems were detected. This is good news for your Mac's hardware.
Fail: This means that the test was completed but a hardware problem was detected. This is bad news for your Mac's hardware. You will need to find out what caused the problem and how to fix it.
Skip: This means that the test was not performed because it was not applicable or not supported by your Mac's hardware. This is neutral news for your Mac's hardware. You don't need to worry about this type of result.
Abort: This means that the test was not completed because it was interrupted by an error or a user action. This is inconclusive news for your Mac's hardware. You will need to run the test again to get a valid result.
How to find more information about the error codes and symptoms
If a test fails, ASD 258 PPC will generate an error code and a symptom code that can help you identify and isolate the hardware problem. The error code is a four-digit number that indicates which component failed and what type of failure occurred. The symptom code is a two-digit number that indicates what symptom was observed during the failure. For example, an error code of 4000 and a symptom code of 01 means that there was a memory failure with no memory installed.
