    Abstract: A system, method, and program product is provided that receives and processes a firmware update at a computer system. The computer system is executing a hypervisor and one or more guest operating systems, and the firmware update corresponds to a hardware device accessible by the computer system. The hardware device is a type that is programmed using an updateable firmware. The hypervisor operating in the computer system processes the received firmware update by first inhibiting use of the device by each of the guest operating systems. After the guest operating systems have been inhibited from using the device, the firmware in the device is upgraded by the hypervisor using the received firmware update. After the firmware has been upgraded, each of the guest operating systems is allowed use of the device.

    Abstract: A system and method that marks whenever a sector on a hard drive is altered. A protected archive bit is maintained for each sector on the hard drive in a secured fashion. Authenticated requests are able to reset the protected archive bit. When a file is changed, the hard drive marks the sectors of the program that have been altered. When the virus protection application executes, it retrieves the sectors that have been altered, identifies the files that correspond to such sectors, and scans the identified files. If a virus has attacked the computer and attached itself to one of the files, the file is identified and scanned and the virus is discovered with appropriate eradication actions performed. An authentication scheme is assigned to a hard drive with a secret that is shared between the drive and the virus protection program and stored in a secure location.

    Abstract: A system, method, and program product is provided that manages a rental computer system by verifying installation of a secure time-day module in a computer system. The computer system is rendered inoperable if the secure time-day module is not installed. A current time-day value is retrieved from the secure time-day module and an end time-day value is retrieved from a secure storage area. The current time-day value is compared to the end time-day value in order to determine whether a rental period has expired. If the rental period has expired, then the user is prevented from using the rental computer system.

    Abstract: A method and system for configuring an operating system in a computer system including language selection during bootup rather than at manufacture. A first aspect of the method and system comprises providing a plurality of operating system images in the computer system, each of the plurality of operating system images being based upon a particular language, selecting one of the plurality of operating system images based on the language supported by the computer system and loading the selected operating system image into the computer system. A second aspect of the method and system comprises providing a language-independent operating system image in the computer system, determining a language supported by the computer system, loading the language-independent operating system image into the computer system, and associating the language supported by the computer system with the language-independent operating system image.

    Abstract: A hard drive having a protected partition is used in the recovery of a BIOS image for a computer system. An EEPROM is used to store a first BIOS image that is used to boot-up the system and recovery code is used to recover a new BIOS image if the first BIOS image has been corrupted. The new BIOS image is stored in the protected partition of the drive. A recover BIOS command is issued whenever the first BIOS image has been corrupted or a remote or local recover BIOS request is received. When the first BIOS is corrupted, the EEPROM is rewritten with the second BIOS image and the system boots with the rewritten first BIOS image. When a recover BIOS request is received in a data packet sent over a communication link, the data packet is authenticated before the first BIOS image is rewritten.
