About:
Flashrom is a utility for identifying, reading, writing, verifying, and erasing flash chips. It is designed to support a wide range of flash memory types, including EEPROM, and is commonly used for BIOS, firmware, and hardware bootloader updates. Its primary value is providing a reliable, open-source method for low-level hardware programming.

Key Features:

Broad hardware support for various chipsets and programmers
Command-line interface for scripting and automation
Support for reading, writing, verifying, and erasing operations
Open-source and cross-platform (Linux, BSD, macOS, Windows)

Use Cases:

Updating BIOS or UEFI firmware on motherboards and laptops
Recovering bricked devices by rewriting firmware
Creating backups of existing firmware images
Developing and testing embedded hardware

Alternatives:

dmidecode – Reads BIOS info from DMI but cannot write or modify firmware.
UEFI Shell tools – Native to UEFI environments, often less flexible for cross-platform use.
