MARUTI Laptop SPI I2C BIOS Chip Read and Write Operations – Installation and Software Guide

Thank you for choosing the MARUTI BIOS Programmer. This guide provides step-by-step instructions for setting up and using the software to read and write BIOS chips effectively.

Driver Installation

1. Plug-and-Play Ready:
   No additional driver installation is required. The device utilizes a default virtual driver that is already installed on your system.

Steps for Reading and Writing BIOS Chips

1. Insert the BIOS Chip:
   Place the BIOS chip securely in the SPI slot of the MARUTI programmer.
2. Select Voltage:
   Set the appropriate voltage on the programmer switch based on your BIOS chip specifications:
   • 1.8V
   • 3.3V
   • 5.0V
3. Launch the Software:
   Open the MARUTI BIOS Programmer software on your computer.
4. Detect the Chip:
   • Click on the “Detect BIOS Chip” option in the software.
   • The software will scan and identify the chip.
5. Select the Chip:
   • From the detected list, select the specific chip model you want to operate on.
6. Read the Chip:
   • Click the “Read Chip” button to read the data stored in the chip.
   • Wait for the process to complete.
7. Save the Read File:
   • After reading, save the BIOS file to a desired location on your computer for backup or reference.
8. Open a New BIOS File:
   • If you wish to update the chip, open the new BIOS file you want to write.
   • Use the “Open” option in the software to load the file.
9. Write to the Chip:
   • Click on the “Write + Unprotect + Verify” option to start writing the new BIOS data to the chip.
   • The software will automatically unprotect the chip, write the new data, and verify the write process.
10. Completion:
    • Once the write process is successfully completed, the operation is done.
    • You may now remove the chip from the programmer.

Important Notes:

• • Ensure the BIOS chip is properly seated in the SPI slot to avoid any errors during the process.
  • Always save the original BIOS file before making any changes for recovery purposes.

• If any issues occur, refer to the troubleshooting section of the user manual or contact MARUTI support.
