  • Patent number: 11663018
    Abstract: An unavailable memory device initialization system includes a memory controller device that is configured to determine whether a memory system includes unavailable memory devices during initialization operations. During the first initialization operations, a BIOS engine identifies unavailable memory device(s) in the memory system that were determined to be unavailable by the memory controller device during the first initialization operations and, in response, stores respective unavailable memory device identifier(s) associated with each unavailable memory device in a non-volatile storage subsystem.

  • Patent number: 11599409
    Abstract: A PPR memory location reporting system includes BIOS coupled to a non-volatile memory system and a volatile memory system. During boot operations, the BIOS identifies a memory location identifier in the non-volatile memory system for a memory location that is included in the volatile memory system and that is associated with PPR, performs PPR operations on the memory location, and determines that the PPR operations on the memory location have failed. In response to determining that the PPR operations on the memory location have failed, the BIOS stores the memory location identifier in a boot error report table that is configured for use by an operating system to prevent use of the memory location by the operating system, and reserves the memory location identifier in a memory map that is configured for use by the operating system to prevent use of the memory location by the operating system.

  • Patent number: 11548132
    Abstract: A power tool includes a case, a motor, a plurality of Hall effect sensors, a first circuit board, and a second circuit board. The Hall effect sensors detect a position of a rotor of the motor and correspondingly generate position signals. A plurality of commutating switches and a first controller are disposed on the first circuit board. A second controller is disposed on the second circuit board, and could transmit a driving signal to the first controller according to the operating signal of an operator interface. The first controller regulates the commutating switches to commutate according to the driving signal and the position signals, thereby to activate the rotor to rotate. With such design, a commutation process and a user operating process are regulated by the two different controllers, which could efficiently simplify the program code installed in each of the controllers and facilitate the maintenance of the controllers.

  • Patent number: 11461178
    Abstract: An information handling system includes a plurality of persistent memory devices and a basic input/output system (BIOS). The BIOS begins a power-on self-test (POST) of the information handling system. During the POST, the BIOS may call a block input/output (I/O) driver to access a memory region within the first persistent memory device. The access of the memory region within the first persistent memory device is to determine whether the first persistent memory device is a bootable persistent memory device. The BIOS may determine whether blocks of the memory region contain bad memory locations. In response to the memory region containing bad memory locations, the BIOS may return a device error message without performing the access of the blocks of the memory region within the first persistent memory device and may boot to an operating system of the information handling system via another bootable device.

  • Patent number: 11392470
    Abstract: An information handling system includes a processor, a plurality of dual in-line memory modules (DIMMs), and a basic input/output system (BIOS). During a power-on self-test (POST), the BIOS may read serial presence detect data from each of the DIMMs, determine a total amount of installed memory. The BIOS may determine whether the total amount of the installed memory exceeds a maximum memory capacity of the processor. If so, the BIOS may remove memory capacity of the DIMMs to create a second total amount of the installed memory that is less than the maximum memory capacity of the processor, configure a memory address decode register with the second total amount of the installed memory, and complete the POST.

  • Patent number: 11360847
    Abstract: A memory scrubbing system includes a persistent memory device coupled to an operating system (OS) and a Basic Input/Output System (BIOS). During a boot process and prior to loading the OS, the BIOS retrieves a known memory location list that identifies known memory locations of uncorrectable errors in the persistent memory device and performs a partial memory scrubbing operation on the known memory locations. The BIOS adds any known memory locations that maintain an uncorrectable error to a memory scrub error list. The BIOS then initiates a full memory scrubbing operation on the persistent memory device, cause the OS to load and enter a runtime environment while the full memory scrubbing operation is being performed, and provides the memory scrub error list to the OS.
