Publication number: 20250021325Abstract: An information handling system includes a memory and a processor. The memory stores a current basic input/output system (BIOS) firmware image. During a regular boot mode of the information handling, the processor creates a first set of tables associated with the current BIOS firmware image, stores the first tables to the memory, and receives a BIOS firmware update image. During a BIOS update boot mode of the information handling system, the processor creates a second plurality of tables associated with the BIOS firmware update image, and compares the first and second tables. In response to a difference being determined between the first and second tables, the processor aborts the BIOS update boot mode and generate an error log.Type: ApplicationFiled: September 27, 2024Publication date: January 16, 2025Inventors: Shekar Babu Suryanarayana, Karunakar Poosapalli, Hung V.

Patent number: 8232345Abstract: A solution with a salt-sensitive polymer binder for use in fibrous webs, where the binder contains a copolymer of carboxylic acid monomer units and ethylenically unsaturated monomer units. The binder solution is prepared by emulsion-polymerizing a copolymer and then neutralizing the copolymer with base to make it water soluble. The binders provide a higher wet strength in concentrated salt solutions than in deionized water, and are particularly suitable for strengthening nonwoven fibrous webs in disposable articles such as wet-wipes, personal care products, diapers, and the like.Type: GrantFiled: February 23, 2011Date of Patent: July 31, 2012Assignee: Celanese International CorporationInventors: Rajeev Farwaha, Steven P.

Patent number: 8201163Abstract: In a Uniform Extensible Firmware Interface (UEFI) environment, a system management mode (SMM) driver and a non-SMM driver may be installed for the same hardware device. Until the SMM driver is available, the non-SMM driver is configured to conduct input/output (IO) transactions directly with the hardware device. The non-SMM driver can utilize native UEFI services to receive a notification that the SMM driver is available. Upon receiving such notification, (or if the SMM driver was already available before the non-SMM driver), the non-SMM driver is reconfigured to redirect all IO requests to the SMM driver, which then conducts the corresponding IO transactions directly with the hardware device. Redirecting all non-SMM IO requests for a hardware device to the SMM driver for the hardware device limits direct access to the hardware device to only one driver, the SMM driver, thereby facilitating the integrity or atomicity of IO transactions.Type: GrantFiled: July 16, 2008Date of Patent: June 12, 2012Assignee: Dell Products, LPInventors: James L. Walker, John J. Hawk, Alok Pant, John Hentosh

Patent number: 8193104Abstract: The present invention is directed to a cationic polymer emulsion binder that may be combined with a cationic active ingredient and used as a non-woven binder. This combination of cationic binder and cationic active ingredient may occur as a mixture of a cationic binder and at least one cationic active ingredient, which is then applied to loose fibers to form a non-woven; or the combination may occur after a non-woven is formed using a cationic binder, and said non-woven is then contacted with a cationic active ingredient. Non-woven wipes of the invention retain far less cationic active ingredients during use, resulting in less waste and less use of the active ingredients for the same effect as wipes made with anionic or non-ionic binders.Type: GrantFiled: November 25, 2002Date of Patent: June 5, 2012Assignee: Celanese International CorporationInventors: John C.

Patent number: 6282662Abstract: Method and apparatus for selectively overriding a prepackaged power management driver of a portable personal computer so that data transmitted to the CPIU of the computer by a device, such as a “real time” serial communicators device connected thereto, is not lost during the CPUs latency “wake up” period following a CPU power-down operation. An override system stored in memory comprises an override flag which may be set or cleared by a user or the computer. If the override flag is set, then the power management system is prevented from reducing power to the CPU so that the occurrence of a CPU latency period and thus potential for loss of data is avoided.Type: GrantFiled: August 4, 1995Date of Patent: August 28, 2001Assignee: Dell USA, L.P.Inventors: Charles Zeller, James L.
