Table 6-4 Computer Setup—Security (continued)
Device Security | Allows you to set Device Available/Device Hidden (default is Device Available) for: | |
| ● | Embedded security device |
| ● | System audio |
| ● | USB controller (varies by model) |
| ● | Network controller |
|
| NOTE: You must disable AMT before trying to hide the network controller. |
| ● | Serial port |
| ● | Parallel port |
| ● | SATA ports (varies by model) |
|
| |
USB Security | Allows you to set Enabled/Disabled (default is Enabled) for: | |
| ● | Front USB Ports |
| ● | Rear USB Ports |
| ● | Accessory USB Ports |
|
| |
Slot Security | Allows you to disable any PCI or PCI Express slot. Default is enabled. | |
|
| |
Network Boot | Enables/disables the computer’s ability to boot from an operating system installed on a network server. | |
| (Feature available on NIC models only; the network controller must be either a PCI expansion card or | |
| embedded on the system board.) Default is enabled. | |
|
| |
System IDs | Allows you to set: | |
| ● | Asset tag |
|
| computer. |
| ● | Ownership tag |
| ● | Universal Unique Identifier (UUID) number. The UUID can only be updated if the current chassis |
|
| serial number is invalid. (These ID numbers are normally set in the factory and are used to uniquely |
|
| identify the system.) |
| ● | Keyboard locale setting for System ID entry. |
|
| |
Master Boot Record | Enables/disables Master Boot Record (MBR) security. | |
Security | The MBR contains information needed to successfully boot from a disk and to access the data stored on | |
| ||
| the disk. Master Boot Record Security may prevent unintentional or malicious changes to the MBR, such | |
| as those caused by some viruses or by the incorrect use of certain disk utilities. It also allows you to | |
| recover the "last known good" MBR, should changes to the MBR be detected when the system is | |
| restarted. | |
| When MBR Security is enabled, the BIOS prevents any changes being made to the MBR of the current | |
| bootable disk while in | |
| NOTE: Most operating systems control access to the MBR of the current bootable disk; the BIOS cannot | |
| prevent changes that may occur while the operating system is running. | |
| Restores the backup Master Boot Record to the current bootable disk. Default is disabled. | |
| Only appears if all of the following conditions are true: | |
| ● | MBR security is enabled |
| ● | A backup copy of the MBR has been previously saved |
| ● | The current bootable disk is the same disk from which the backup copy was saved |
