While the splash screen is displayed, make one of the following selections: • Press F2 to enter the BIOS Setup. • Press Ctrl+A to enter the Adaptec SCSISelect utility. Refer to page 40 for information about the Adaptec SCSISelect Utility. • Press Esc to view POST diagnostic messages and change the boot device priority for this boot only. • Press F12 to perform a network boot. 3. If you do not make one of the above selections and do not have a device with an operating system loaded, the boot process continues and the server beeps once. The following message is displayed: Operating System not found If the system halts before POST completes running, the server emits a beep code indicating a fatal system error that requires immediate attention. If POST can display a message on the video display screen, it causes the speaker to beep twice as the message appears. Write down both the screen display and the beep code you hear; this information is useful for your service representative. For a listing of common beep codes and error messages that POST can generate, refer to Chapter 7, Technical Reference.

Press Enter and the boot process continues.
