摘要:
A method for booting into computer memory a non-operating system (O.S.) program from a hard disk drive (HDD) prior to booting into memory an O.S. from the HDD. The method includes establishing a table of contents (TOC) on the HDD that contains entries for special O.S. programs. A pointer to the TOC is placed in non-volatile memory of the computer that is associated with the HDD, and when BIOS of the computer is prompted to load into memory one of the special O.S. programs, the pointer is accessed and used to locate the TOC, which in turn is accessed to load the special O.S. program.

A “setmax” command is issued in BIOS to hide the service area (HPA) of a HDD during normal operation, so that the HPA cannot be accessed or erased inadvertently by the user or by a virus. Pressing a special key (e.g., F11) during booting permits access to the HPA.
摘要:
In the event of a virally infected MBR on a hard disk drive that might prevent booting, a service MBR in a hidden protected area (HPA) can be used to boot a service O.S., and then the service MBR can be replaced with a previously backed-up MBR, also in the HPA, to mount any missing partitions.

An apparatus, system, and method are disclosed for selecting a waking process. An input module receives a specified input during the off state of a data processing device. In addition, the input module stores the input in the storage module. The storage module may be integrated within the input module. The input module activates the data processing device in response to the input. A wake module retrieves the input from the storage module. In addition, the wake module determines a process that corresponds to the input. The wake module wakes the data processing device using the process.

A system, method, and program product is provided that has a virtualized environment provided by a hypervisor. In the virtualized environment, one or more guest operating systems operate simultaneously with a privileged operating system. One of the guest operating systems identifies a device software update, such as a device driver or firmware update, corresponding to a hardware device that is attached to the computer system. The hypervisor is used to notify the privileged operating system of the device software update. When the privileged operating system is notified of the update, the privileged operating system uses one or more techniques to deny the guest operating systems access to the device. The privileged operating system then updates the device software update. After the device software update has been applied, the privileged operating system resumes access between the guest operating systems and the hardware device.

A data processing system and method of password protecting the boot of a data processing system are disclosed. According to the method, in response to an attempt to boot the data processing system utilizing a boot device, the boot device is interrogated for a password. If the boot device supplies password information corresponding to that of a trusted boot device, the data processing system boots utilizing the boot device. If, however, the boot device does not supply password information corresponding to that of a trusted boot device, booting from the boot device is inhibited. In a preferred embodiment, the password information comprises a unique combination of the boot device's manufacturer-supplied model and serial numbers.

A method, system and computer readable medium containing programming instructions for tracking a secure boot in a computer system having a plurality of devices is disclosed. The method, system and computer readable medium include providing an embedded security system (ESS) in the computer system, wherein the ESS includes at least one boot platform configuration register (PCR) and a shadow PCR for each of the at least one boot PCRs, initiating a platform reset to boot the computer system via BIOS, and, for a device booted, generating a measurement value for the device and extending that value to one of the at least one boot PCRs and its corresponding shadow PCR. The system, method and computer readable medium of the present invention also includes comparing the measurement values of the boot PCRs to their corresponding shadow PCRs, whereby the computer system is trusted if the measurement values match.

A method is disclosed for securely updating system attributes of a client computer with a BIOS and includes signing a public key of a secure server with a private key of the BIOS prior to completion of manufacturing of the client computer to create an encrypted public key and embedded private key stored at the server. The method includes receiving at the server a request packet transmitted from the client computer requesting system attribute modification, encrypting the request packet to create an encrypted packet, and transmitting a return packet to client computer comprising the encrypted packet, the server's public key, and server instructions. The client computer decrypts the request packet using the server's public key and compares it to the original request packet, and if identical, executes the server instructions to modify the client computer's boot block to update client computer's system attributes.
