Configuration Software and Utilities 41
3. After pressing <F2> or <Esc> during POST, you can press <Ctrl+A> to run the SCSISelect
Utility. For more information, see “Running the Adaptec SCSISelect Utility” on page42.
4. If you do not press <F2> or <Esc> and do NOT have a device with an operating system loaded,
the boot process continues and the system beeps once. The following message is displayed:
Operating System not found
5. At this time, pressing any key causes the system to attempt a reboot. The system searches all
removable devices in the order defined by the boot priority.
BIOS Setup
You can run BIOS Setup with or without an operating system being present. BIOS Setup stores
most of the configuration values in battery-backed CMOS; the rest of the values are stored in flash
memory. The values take effect when the system is booted. POST uses these values to configure
the hardware. If the values and the actual hardware do not agree, POST generates an error
message.
Record BIOS Setup Settings
Record your BIOS Setup settings. If default values ever need restoring (after a CMOS clear, for
example), you must run BIOS Setup again. Your record will make this much easier.

If BIOS Setup Is Inaccessible

If you have a misconfigured diskette drive, and you cannot use BIOS Setup to correct the problem,
you might need to clear CMOS memory. To clear CMOS, either of two methods can be used.
1. Press the reset button and hold it down for four seconds or more, and then, while holding the
reset button down, press the power button. Release both buttons at the same time.
2. Move the Clear CMOS jumper found on the configuration jumper block on the baseboard.

Temporarily Changing the Boot Device Priority

During POST, you can change the boot device priority for the current boot process. The changes
are not saved for the next boot process.
1. Boot the server.
2. At any time during POST, press <Esc>. When POST completes, a popup Boot menu displays.
3. Use the arrow keys to highlight the device you want the server system to boot from first. For
example, if you want the server system to boot from the CD-ROM first, you select “ATAPI
CD-ROM Drive.”
NOTE
One of the selections on the popup Boot menu is “Enter Setup.” Selecting
this option brings you into the BIOS Setup.
4. Press <Enter>.
5. The boot process continues. When finished, a system prompt displays.
