Displays a screen that allows you to configure all system drives including: enabling and disabling the diskette drive, configuring the drive type and drive geometry information for primary and secondary drives, and enabling and disabling DMA transfers for the internal IDE and SATA (when available) hard-drive interface. | |
Determines the order in which the system searches for boot devices during system startup. Available options can include the diskette drive, CD drive, hard drives, and network. | |
Displays the amount of installed system memory and memory speed. This option does not have user-selectable settings. | |
Displays information related to the processor (speed, cache size, and so on), and allows you to lower the speed at which the processor runs after system boot to accommodate speed-sensitive applications, and to enable Hyper-Threading (if supported by your processor). | |
See "Integrated Devices Screen." | |
Displays a screen that allows you to configure the system's power-management features, including the suspend mode (S1 or S3), AC power recovery, and low-power mode. | |
Displays a screen that allows you to configure the security features of your system, including passwords, POST hotkeys, chassis intrusion, and Boot Integrity Services (BIS) requests. See "System and Setup Password Features" for more information about setting up passwords. | |
Determines whether your system starts up with the NumLock mode activated on 101- or 102-key keyboards (does not apply to 84-key keyboards). | |
Enables or disables reporting of keyboard errors during the POST. Enable this option for host systems that have keyboards attached. Select Do Not Report to suppress all error messages relating to the keyboard or keyboard controller during POST. This setting does not affect the operation of the keyboard itself if a keyboard is attached to the system. | |
Displays a screen that allows you to configure the system's Auto Power On features, including setting the time and days of the week to turn on the system automatically. The selections are every day or every Monday through Friday. Time is kept in a 24-hour format (hours:minutes). Change the start-up time by pressing the right- or left-arrow keys to increase or to decrease the numbers or type numbers in both the date and time fields. This feature does not work if you turn off the system using a power strip or surge protector. | |
When set to On, the system turns on when a NIC or a modem with Remote Wake Up capabilities receives a wake-up signal. When set to On w/Boot to NIC, the system attempts a network boot prior to using the boot sequence. Normally, the system can be turned on remotely from a state of Suspend, Hibernate, or Off. When Low Power Mode is enabled (from the Power Management window), the system can only be turned on remotely from the Suspend state. | |
Specifies how quickly the system boots if an operating system has requested a simple boot. When set to On, the system boots in 10 seconds or less, skipping certain configurations and tests. When set to Off, these tests and configurations are not skipped. | |
Determines the maximum amount of memory available to the operating system. On sets the maximum memory to 256 MB. Off makes all of the system memory available to the operating system. Some operating systems cannot be installed with more than 2 GB of system memory. Enable this option (On) during operating system installation and disable (Off) after installation. | |
Sets the hard drive's acoustic mode. When set to Bypass, the system does not test or change the mode. When set to Quiet, the drive operates at its most quiet setting. When set to Suggested, the drive operates at the acoustic level suggested by the manufacturer (between Quiet and Performance modes). When set to Performance, the drive operates normally. NOTE: Any setting other than Performance may cause a loss in drive performance. | |
Displays a screen that allows you to view the system event log and its status and to clear the log. | |
Displays the customer-programmable asset tag for the system if an asset tag has been assigned. To enter an asset tag of up to 10 characters into NVRAM, see "Asset Tag Utility." |
