You can view server configuration information (such as system configuration, memory contents, interrupt request (IRQ) use, direct memory access (DMA) use, device drivers, and so on) by selecting Hardware Info from the top of the screen. If the diagnostic programs do not detect any hardware error but the problem persists during normal server operations, a software error might be the cause. If you suspect a software problem, see the information that comes with the software package. Diagnostic error codes are listed at "Diagnostic error codes" on page 211. Viewing the test log When the tests are completed, you can view the test log by selecting Utility from the top of the screen and then selecting View Test Log. Notes: 1. You can view the test log only while you are in the diagnostic programs. When you exit the diagnostic programs, the test log is cleared (saved test logs are not affected). To save the test log so that you can view it later, click Save Log on the diagnostic programs screen and specify a location and name for the saved log file. 2.
