2Chapter 2: POST DiagnosticsPower-On Self-Test (POST) ErrorsWhenever a recoverable error occurs during POST, the BIOS displaysan error message describing the problem.If a system boot is incomplete (for example, the system is turned offwhile it is going through the POST), then the next time the system ispowered on you may get a message stating that the previous boot wasincomplete. The BIOS will revert to safe values for the chip set, caches,I/O components, etc. This provides the best possibility of returning tothe Setup routine and to normal functioning, but these values do notalways produce maximum system performance. To achieve maximumperformance after the BIOS has reverted to safe values, re-enter Setupand select the maximum performance values.If, for example, the terminal was simply turned off during POST, youcan return to the maximum performance values by simply enteringSetup and exiting or by rebooting.During POST, you are asked to press and boot with the defaultconfiguration. If you simply presses and then do not later returnto Setup, the system will boot; but the external cache will not beenabled, even though the default configuration will enable the cache.
