Important Preparations

Before proceeding, take the following precautions:

Step-by-Step Guide to Dumping the BIOS

Step 1: Identify Your Toughbook Model

Locate the model number of your Toughbook. You can find this:

On a label under the laptop.
Within the BIOS settings (access by pressing a specific key like F2 during startup).

Step 2: Obtain the Right Tool

Most Panasonic Toughbooks use AMI (American Megatrends Inc.) BIOS, making the AMI Firmware Update Utility (AFU) a suitable tool. You can download it in two versions:

AFUWIN for Windows.
AFUDOS for DOS environments.

Step 3: Download and Install AFU Utility

Visit the AMI website or a trusted source to download the utility.
Select the appropriate version for your operating system (Windows or DOS).
Install or copy the utility to a suitable location on your laptop or USB drive.

Step 4: Prepare a Bootable USB (For DOS Users)

If using AFUDOS, create a bootable USB drive:

Format the USB drive to FAT32.
Use tools like Rufus to make it bootable with DOS.
Copy the AFUDOS utility onto the USB drive.

Step 5: Dump the BIOS

Using AFUWIN (Windows)

Open AFUWIN as an administrator.
Go to the Information tab.
Click the Save button to start the BIOS backup.
Specify the file name and destination for the dump file.

Using AFUDOS (DOS)

Insert the bootable USB into your Toughbook.
Restart the laptop and boot from the USB.
At the DOS prompt, type the following command:

mathematica

AFUDOS.EXE /O biosbackup.rom
Replace biosbackup.rom with your preferred file name.

Step 6: Verify the BIOS Dump

After dumping the BIOS, check:

File Size: Ensure it matches typical BIOS file sizes (several MBs).
Integrity: Use tools to verify file integrity or compare with known hashes.

Step 7: Store the BIOS File Safely

Save the dumped BIOS file in multiple secure locations:

External hard drives.
Cloud storage services (e.g., Google Drive, OneDrive).
