In the past, BIOS settings were stored on a ROM (Read-Only Memory) chip on the computer’s motherboard. However, with the advancement in technology, modern systems now store the BIOS settings on flash memory. This allows for easier firmware upgrades without the need to physically remove chips from the motherboard.

Storing the BIOS settings on flash memory also enables user-friendly updates to introduce new features or fix issues, making it a more convenient and flexible option.


CMOS Memory

One of the key components where the BIOS settings are stored is the CMOS (Complementary Metal-Oxide-Semiconductor) memory. The saved BIOS configuration data resides in the CMOS chip, which retains the settings even when the power is turned off.

The CMOS memory plays a critical role in preserving the BIOS settings, ensuring that the computer system can retain and recall the configuration data each time it is powered on.


It’s important to note that there is a distinction between UEFI (Unified Extensible Firmware Interface) and traditional BIOS. While the location of the settings may be similar, UEFI represents a newer and more advanced firmware interface compared to the traditional BIOS.

UEFI offers several advantages over BIOS, including support for larger hard drives, faster boot times, improved security features, and a more user-friendly interface. However, both UEFI and BIOS store their settings in non-volatile memory, with UEFI typically using flash memory for this purpose.
