TEMPERATURE BASED DECISION FEEDBACK EQUALIZATION RETRAINING
An information handling system includes a memory subsystem and a basic/input out system (BIOS). The BIOS performs multiple trainings of the memory subsystem, and each of the trainings is performed at a different temperature. The BIOS stores multiple derating values in a derating table of the BIOS, and each of the derating values corresponds to a respective tap value at a respective temperature. During a subsequent power on self test of the information handling system, the BIOS performs a first training of the memory subsystem, and stores a first set of tap values. During a runtime of the information handling system, a memory controller determines whether a temperature of the information handling system has changed by a predetermined amount. In response to the temperature changing by the predetermined amount, the memory controller utilizes the derating values in the derating table to automatically update the tap values.
Data storage device restoring method
A data storage device restoring method is provided, which is adapted to a data storage device. The data storage device includes an SSD controller, a power management circuit, a non-volatile memory, and a reset circuit. The data storage device restoring method includes: the power management circuit determines whether a normal signal from the SSD controller is received within a predetermined time; if not, the power management circuit resupplies power to the data storage device but stops supplying power to the non-volatile memory, thereby the SSD controller stays in a read-only memory mode to automatically execute the data storage device restoring process.
Hybrid firmware code protection
A firmware protection module implements a hybrid firmware protection scheme on a computing device. The firmware protection module intercepts a message from a processor to a memory of the computing device. The message includes a command and an address in the memory corresponding to a firmware module stored in the module. The firmware protection module determines whether the command in the message is prohibited and whether the address in the message is protected. Responsive to a determination that the command is prohibited and the address is protected, the firmware protection module prevents at least a portion of the message from reaching the memory.
Non-volatile storage device having fast boot code transfer with low speed fallback
A storage system comprises a non-volatile memory configured to store boot code and a control circuit connected to the non-volatile memory. In response to a first request from a host to transmit the boot code, the storage system commences transmission of the boot code to the host at a first transmission speed. Before successfully completing the transmission of the boot code to the host at the first transmission speed, it is determined the boot code transmission has failed. Therefore, the host will issue a second request for the boot code. In response to the second request for the boot code, and recognizing that this is a fallback condition because the previous transmission of the boot code failed, the storage apparatus re-transmits the boot code to the host at a lower transmission speed than the first transmission speed.
MULTIPLE BLOCK ERROR CORRECTION IN AN INFORMATION HANDLING SYSTEM
An information handling system includes a first memory and a baseboard management controller. The first memory stores a first firmware partition and a second firmware partition. The baseboard management controller includes a second memory. The baseboard management controller begins execution of a DM-Verity daemon, and performs periodic patrol reads of the first firmware partition. The baseboard management controller detects one or more block failures in the first firmware partition, and stores information associated with the one or more block failures in a message box of the second memory. In response to the entire first firmware partition being scanned, the baseboard management controller switches a boot partition from the first firmware partition to the second firmware partition, and initiates a reboot of the information handling system.
Saving page retire information persistently across operating system reboots
Examples described herein include systems and methods for retaining information about bad memory pages across an operating system reboot. An example method includes detecting, by a first instance of an operating system, an error in a memory page of a non-transitory storage medium of a computing device executing the operating system. The operating system can tag the memory page as a bad memory page, indicating that the memory page should not be used by the operating system. The operating system can also store tag information indicating memory pages of the storage medium that are tagged as bad memory pages. The example method can also include receiving an instruction to reboot the operating system, booting a second instance of the operating system, and providing the tag information to the second instance of the operating system. The operating system can use the tag information to avoid using the bad memory pages.
Systems and methods for self-healing and/or failure analysis of information handling system storage
Systems and methods are provided that may be implemented to perform failure analysis and/or self-healing of information handling system storage. In one example, an information handling system may perform self-recovery actions to self-heal system storage issues when there is a OS boot failure due to a failure to detect a system storage drive by determining one or more possible recovery actions based on a current system storage drive status retrieved by an embedded controller (EC) or other programmable integrated circuit of the information handling system. In another example, manufacturing quality control analysis may be performed on boot failure information that is collected at a remote server from multiple failed information handling systems.
HANDLING MEMORY ERRORS IN MEMORY MODULES THAT INCLUDE VOLATILE AND NON-VOLATILE COMPONENTS
In one example in accordance with the present disclosure, a system for handling memory errors includes a memory module having volatile components and non-volatile components. The system includes a BIOS chip having BIOS code and a BIOS non-volatile (NV) memory. The BIOS NV memory stores error data associated with the memory module that was stored prior to a power-on or reset of the system. The system includes a processor to execute the BIOS code to, after the power-on or reset of the system end before an operating system is loaded; (1) read, from the BIOS NV memory, the error data; and (2) determine, based on the error data, whether to take a corrective action with respect to the memory module.

COMPUTER PROGRAM PRODUCT THAT INCLUDES A FIRMWARE STRUCTURE, AND BOOTING METHOD FOR A CONTROL SYSTEM
A computer program product embodied on a non-transitory computer readable medium of a control system includes a firmware program file, a signature detection module that causes a processor to detect whether a pre-defined signature is present; a booting module that causes the processor to perform, after it is determined that the pre-defined signature is not present in the main block, operations of power management and pin initiation included in the booting sequence; and a flashing module that causes the processor to perform, in response to receipt of a flashing command, a flashing operation that includes overwriting the firmware program file with an update firmware program file.
