When MBR Security is enabled, the BIOS prevents any changes being made to the MBR of the

current bootable disk while in MS-DOS or Windows Safe Mode.

✎

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.

Each time the computer is turned on or restarted, the BIOS compares the MBR of the current

bootable disk to the previously saved MBR. If changes are detected and if the current bootable

disk is the same disk from which the MBR was previously saved, the following message is

displayed:

1999—Master Boot Record has changed.

1. Press any key to enter Setup to configure MBR Security.

2. Upon entering Computer Setup, you must disable the MBR Security feature.

You must know the supervisor password, if one exists.

If changes are detected and if the current bootable disk is not the same disk from which the MBR

was previously saved, the following message is displayed:

2000—Master Boot Record Hard Drive has changed.

1. Press any key to enter Setup to configure MBR Security.

2. Upon entering Computer Setup, you must disable the MBR Security feature.

You must know the supervisor password, if one exists.

In the unlikely event that the previously saved MBR has been corrupted, the following message is

displayed:

1998—Master Boot Record has been lost.

1. Press any key to enter Setup to configure MBR Security.

2. Upon entering Computer Setup, you must disable the MBR Security feature.

You must know the supervisor password, if one exists.
