HP BIOS configuration (REPSET) functionality

The HP BIOS Configuration utility supports the following functions for Windows key insertion:

 English

 MS Digital Marker

 “Value”

The Values are:

 Unlock – used to unlock the key for writing.

– Requires reboot with Physical Presence Check

– Not required in MPM mode or first write after re-flash

 Key – Text string representation of Windows key

– Use all FFh to clear the key in the ACPI MSDM table.

Physical Presence Check

To prevent malicious software attacks, a Physical Presence Check must be performed to inject a “new” key or “clear” a

key. During the next reboot after a new key is written to Public WMI, the following message will be displayed to the user.

A Physical Presence Check is not required if the system is in Manufacturing Mode or if the key has not been set since it

was last cleared by a complete BIOS re-flash.

To complete the process of inserting a new key, the technician or user must enter the verification code “9466” when the

message is displayed. The message will be displayed for 60 seconds. If the code is not entered, the key will not be

changed, and the boot will continue.

Computrace

The Absolute Computrace Preboot module writes to the hard disk if it detects the needed hard drive components are no

longer present. This provides persistent support and prevents the malicious deletion of files from the system. However,

this method can impact OS stability. Preboot module support will fail when the OS partition or the hard drive is

encrypted.

In Win8, a new method has been proposed. The WPBT is a fixed Advanced Configuration and Power Interface (ACPI) table

that enables boot firmware to provide Windows with a platform binary that the operating system can execute. The

binary handoff medium is physical memory, allowing the boot firmware to provide the platform binary without

modifying the Windows image on disk. In the initial version, the WPBT simply contains a physical address pointer to a

flat, Portable Executable (PE) image that has been copied to physical memory.

If you are running Win7 or an older OS and the HDD is not encrypted, use the older method (changing the OS file).

If you are running Win8 and the HDD is encrypted, publish WPBT. For older OSes, the WPBT will be ignored.
