2.1.2 Using AFUDOS to copy the current BIOS
The AFUDOS.EXE utility can also be used to copy the current system BIOS
settings to a floppy or hard disk. The copy can be used as a backup in case the
system BIOS fails or gets corrupted.
1. At the DOS prompt, type the command line:
afudos /o[filename]
where “filename” can be any user-provided filename of not more than eight
alphanumeric characters for the main filename and three alphanumeric
characters for the extension name.
Press <Enter>.
2. The utility will copy the current system BIOS by default to the floppy disk. Make
sure that the floppy disk is not write-protected and has enough space (at least
600KB) to store the file.
The BIOS information on the screen is for reference only. What you see on your
screen may not be exactly the same as shown.
When the BIOS copy process is complete, the utility returns to the DOS prompt.
