AFUDOS (Award Flash Update DOS) is a utility program designed for updating BIOS firmware on motherboards that use Award or Phoenix-Award BIOS. This DOS-based tool is particularly popular among computer enthusiasts and technicians for its reliability in BIOS flashing operations.
The program is typically used by booting into DOS mode and running commands in the following format: AFUDOS /i[filename].rom
Key features of AFUDOS include:
It's important to note that AFUDOS should be used with caution, as incorrect BIOS updates can render a motherboard inoperable. Users should always ensure they have the correct BIOS file for their specific motherboard model and follow the manufacturer's instructions carefully.
The tool is commonly distributed by motherboard manufacturers alongside BIOS update packages, ensuring compatibility and safe operation during the update process.
