The driver is a software component that helps the operating system communicate with Intel's SPI controller hardware, which is often used in systems for tasks such as firmware management, system diagnostics, and communication with non-volatile memory chips (like BIOS or EEPROM). This driver is commonly found in systems that utilize Intel chipsets and may be part of the chipset or platform driver package.

In many cases, the Intel SPI controller interacts with the system's BIOS/UEFI and is critical for tasks like reading and writing firmware, supporting system recovery, or updating the BIOS. The "7E23" designation refers to a specific version or model of the SPI controller, which may vary depending on your system's chipset.
