Configuration Software and Utilities 43
Power-On Self-Test (POST)
Each time you turn on the system the BIOS begins execution of the Power-On Self-Test (POST).
POST discovers, configures, and tests the processors, memory, keyboard, and most installed
peripheral devices. The time needed to test memory depends on the amount of memory installed.
POST is stored in flash memory.
1. Turn on your video monitor and system. After a few seconds, POST begins to run and displays
a splash screen.
2. While the splash screen is displayed:
• Press <F2> to enter the BIOS Setup (see “Using BIOS Setup”)
OR
• Press <Esc> to view POST diagnostic messages and change the boot device priority for this
boot only (see “Temporarily Changing the Boot Device Priority” on page 53.)
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 page 54.
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.
Using BIOS Setup
This section describes the BIOS Setup options. Use BIOS Setup to change the system
configuration defaults. 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. You must run BIOS Setup to specify the correct configuration.
Run BIOS Setup to modify all server board features, such as:
• Defining the diskette drive
• Defining the serial port(s)
• Set time/date (to be stored in RTC)
• Configure hard drive(s)
• Specify boot device sequence
• Enable SCSI BIOS
• Enable Server Management Features
• Setup system passwords
