[. . . ] Observe the post-installation instructions described on page 40. 4 BIOS setup This chapter gives information about the system BIOS and discusses how to configure the system by changing the settings of the BIOS parameters. 91 BIOS setup BIOS setup is a hardware configuration program built into the system's Basic Input/Output System (BIOS). Since most systems are already properly configured and optimized, there is no need to run this utility. The BIOS setup utility stores basic settings for your server. You will need to run this utility under the following conditions: · · When changing the system configuration When a configuration error is detected by the system and you are prompted ("Run Setup" message) to make changes to the BIOS setup Note: If you repeatedly receive Run Setup messages, the battery may be bad. In this case, the system cannot retain configuration values in CMOS. Ask a qualified technician for assistance. · · When redefining the communication ports to prevent any conflicts When changing the password or making other changes to the security settings BIOS setup loads the configuration values in a battery-backed nonvolatile memory called CMOS RAM. This memory area is not part of the system RAM which allows configuration data to be retained when power is turned off. Before you run BIOS setup, make sure that you have saved all open files. The system reboots immediately after you close the setup. 92 4 BIOS setup Entering BIOS setup Power on the server to start the system POST process. During bootup, press F2 to enter the BIOS setup screen. Note: You must press F2 while the system is booting. This key does not work during any other time. There are several tabs on the setup screen corresponding to the eight primary BIOS menus. Valid values for hour, minute, and second are: Hour: 00 to 23 Minute: 00 to 59 Second: 00 to 59 96 4 BIOS setup Advanced The Advanced menu contains parameter values that define how the system behaves on startup. Warning!Be cautious in setting parameter values in the Advanced menu as any incorrect value may cause the system to malfunction. Press Enter to enter the submenu screen of the parameters shown in the screen below. 97 Processor The Processor submenu displays CPU settings such as type, actual speed, cache size and other CPU related settings. Parameter Core Frequency System Bus Frequency Hyper Threading Technology Enhanced Intel SpeedStep Technology Description Indicates the processor clock speed. Indicates the processor front side bus speed. Enables or disables the Hyper-Threading Technology function of the processor. Option Enabled Disabled When set to Enabled, this feature allows the OS to reduce power consumption. When set to Disabled, the system operates at maximum CPU speed. Enables or disables the secondary processor core. Enabled Disabled Dual Core Enabled Disabled 98 4 BIOS setup Parameter Virtualization Technology Description Enables or disables the system to run multiple operating systems and applications in different partition. When Enabled, the processor disables code execution when a worm attempts to insert a code in the buffer preventing damage and worm propagation. When Disabled, the processor forces the Execute Disable Bit feature flag to always return to 0. Note: This parameter is hidden if the processor does not support this function. Option Disabled Enabled Execute Disable Bit Enabled Disabled Hardware Prefetcher Enables or disables the speculative prefetch unit within the processor(s). Note: Changing this feature may affect system performance. Enabled Disabled Adjacent Cache Line Prefetch When Enabled, cache lines are fetched in pairs (even line + odd line) When Disabled, only current cache line required is fetched. Note: Changing this feature may affect system performance. Enabled Disabled Processor Re-Test When Enabled, all processors will be activated and retested on the next boot. [. . . ] When initialization is complete, press any key to continue. Press Esc to return to the Management Menu.
