Flash Method 1 (Tested):

1. Copy the file to a USB.
2. Use a compatible CPU to boot to BIOS.
3. Enter M-Flash.
4. Select the BIOS file.

Flash Method 2 (Untested but should work):

1. Download the file to a Linux computer with Flashrom.
2. Connect an SPI flasher to the computer (CH341A is recommended).
3. Connect a SOIC-8 test clip to the SPI flasher, and place the clip onto the BIOS chip.
4. Open a terminal and execute the following command to dump the existing BIOS as a backup (replace 'ch341a_spi' if you have a different flasher):

sudo flashrom --programmer ch341a_spi -r backup.bin
 

5. Once that is finished, execute the following command to write the new BIOS:

sudo flashrom --programmer ch341a_spi -w E7978IMS.1G0
