Security | Master Boot Record | Allows you to enable or disable Master Boot |
(continued) | Security | Record (MBR) 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 current bootable disk to the |
|
| |
|
| detected, you are given the option of saving |
|
| the MBR on the current bootable disk, |
|
| restoring the |
|
| disabling MBR Security. You must know the |
|
| setup 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. |
Support for Computer Setup options may vary depending on your specific hardware configuration.
