Order in Which POST Tests Are PerformedEach time the system is powered on, or a reset is performed, the POST is executed. The POST process verifies the basic functionality of the system components and initializes certain system parameters.
The POST starts by displaying a graphic screen of the HP PC Workstation’s logo when the PC Workstation is restarted. If you wish to view the POST details, press Esc to get the HP Summary Screen.
If the POST detects an error, the screen switches to text mode, and a detailed error message is displayed inside a view system errors screen, in which the error message utility (EMU) not only displays the error diagnosis,
but the suggestions for corrective action (refer to for a brief summary).On the HP Kayak XU700 Minitower PC Workstation, the LCD status panel displays either a message, a POST code number (refer to page 105) or an EMU code.
Devices such as memory and newly installed hard disks, are configured automatically. The user is not requested to confirm the change.
During the POST, the BIOS and other ROM data are copied into
