| Security | DriveLock* | Allows you to assign or modify a master or user password for |
| |
| (continued) |
| certain hard drives. When enabled, the user is prompted to | ||
|
|
| provide one of the DriveLock passwords during POST. If neither | ||
|
|
| is successfully entered, the hard drive will remain inaccessible | ||
|
|
| until one of the passwords is successfully provided during a | ||
|
|
| subsequent | ||
|
|
| This selection will only appear when at least one drive that | ||
|
|
| supports the DriveLock feature is attached to the system. | ||
|
|
|
| ||
|
| Master Boot | Allows you to enable or disable Master Boot Record (MBR) |
| |
|
| Record Security* | Security. When enabled, the BIOS rejects all requests to write to | ||
|
|
| the MBR on the current bootable disk. Each time the computer is | ||
|
|
| powered on or rebooted, the BIOS compares the MBR of the | ||
|
|
| bootable disk to the previously saved MBR. If changes are | ||
|
|
| detected, you are given the option of saving the MBR on the | ||
|
|
| current bootable disk, restoring the previously saved MBR, or | ||
|
|
| disabling MBR security, You must know the password if one is | ||
|
|
| set. |
|
|
|
|
| ✎ | Disable MBR Security before intentionally changing the | |
|
|
|
| formatting or partitioning of the current bootable disk. | |
|
|
|
| Several disk utilities (such as FDISK and FORMAT) attempt to | |
|
|
|
| update the MBR. If MBR Security is enabled and disk | |
|
|
|
| accesses are being serviced by the BIOS, write requests to | |
|
|
|
| the MBR are rejected, causing the utilities to report errors. If | |
|
|
|
| MBR Security is enabled and disk accesses are being | |
|
|
|
| serviced by the operating system, any MBR change will be | |
|
|
|
| detected by the BIOS during the next reboot, and an MBR | |
|
|
|
| Security warning message will be displayed. | |
|
|
|
|
| |
|
| Save Master | Saves a backup copy of the Master Boot Record of the current | ||
|
| Boot Record* | bootable disk. | ||
|
|
| ✎ Only appears if MBR Security is enabled. |
| |
|
| Restore Master | Restores the backup Master Boot Record to the current bootable | ||
|
| Boot | disk. | ||
|
| Record* | ✎ 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 of the MBR was saved. | |
|
|
|
|
| |
|
| Device Security | Enables/disables serial ports A & B; parallel and USB ports; | ||
|
|
| system audio; network controller (some models); and SCSI | ||
|
|
