  • Publication number: 20240330091
    Abstract: An information handling system may include a processor, one or more audio speakers configured to play back audible audio signals, and a basic input/output system (BIOS) comprising a program of instructions comprising boot firmware configured to be the first code executed by the processor when the information handling system is booted or powered on in order to initialize the information handling system for operation. The BIOS may be further configured to monitor for an error occurring during execution of the BIOS and responsive to an error occurring during execution of the BIOS, cause the one or more audio speakers to play back a sequence of one or more multi-frequency audio signals encoding an identity of the error.

  • Publication number: 20240331795
    Abstract: It is checked, using machine learning, whether at least one fail bit in a memory block of a memory is unrepairable, according to a location of the at least one fail bit, and an available repair resource in the memory. When the checking indicates that the at least one fail bit is not unrepairable, it is determined whether a CSP containing constraints is solvable. The constraints correspond to the location of the at least one fail bit in the memory block, and the available repair resource. In response to determining that the CSP is not solvable, the memory block is marked as unrepairable or the memory is rejected. In response to the checking, using the machine learning, indicating that the at least one fail bit is unrepairable, the memory block is marked as unrepairable or the memory is rejected, without making further determinations as to repairability of the memory block.
