About the System
Using the System Setup Program 2 Setup Menu The computer employs the latest AMI Core BIOS, which is stored in Flash memory. The Flash memory supports the Plug and Play specification, and contains a BIOS Setup program, the Power On Self Test (POST) routine, and the PCI auto-configuration utility. This system supports system BIOS shadowing which enables the BIOS to execute from 64-bit onboard write-protected DRAM.
BIOS Setup Options at Boot You can initiate SETUP by pressing the respective keys during the POST: Enter the BIOS Setup Console Redirection The console redirection allows a remote user to diagnose and fix problems on a server, which has not successfully booted the operating system (OS). The centerpiece of the console redirection is the BIOS Console. The BIOS Console is a Flash ROM-resident utility that redirects input and output over a serial or modem connection.
For console redirection, an escape sequence starts with an escape character. This character can be entered in a variety of different ways depending on the requirements of your terminal emulation software. For example, 0x1b, ^[, and refer to the same escape character. The following table lists the escape sequence that must be sent to represent a special key or command.
The Legend Bar The legend bar is at the side of the Setup screen. The keys in the legend bar allow you to navigate through the various setup menus. The following table lists the keys found in the legend bar with their corresponding alternates and functions.
Access Level The Access Level property controls who has access to the control (supervisor or user). Table 2-1 summarizes the effect of Access Level on a control. Table 2-1.

Memory Issues If you have installed incompatible memory modules, the system may not boot. Verify the memory you've installed has been tested with your board. If the installed memory is compatible, remove and reinstall the memory modules. Defective memory modules may cause boot errors. To isolate a specific memory module as defective, boot the system with just one memory module installed at a time. Monitor Issues Monitor configurations can cause boot failure.
• If the PDU or the AC outlet has an on/off switch, make sure that it is on and verify that the outlet is supplying current. • Check for foreign objects inside the chassis such as screws that can short circuit connections. Cable Issues Ensure that all cable connections, both internal and external, are attached correctly and securely. Electrical Short or Overload Remove non-essential items such as extra controller cards or IDE/ATAPI devices to check for shorts and over-loads.
Software Changes If you recently installed new software or new device drivers: Try booting into Safe Mode and uninstall the new software or driver. If you can now boot normally, there may be a compatibility issue between the new software or driver and some component in your system. Contact the software manufacturer for assistance. BIOS Changes Changes to some advanced BIOS settings (such as those found in the "Advanced Menu" on page 19) can cause boot issues.
Installation Problems Perform the following checks if you are troubleshooting an installation problem: • Check all cable and power connections (including all rack cable connections). • Unplug the power cord, and wait one minute. Then reconnect the power cord and try again. • If the network is reporting an error, see if there is enough memory installed and disk space available. • Remove all added options, one at a time, and try to power up the system.
