It explains how to download the BIOS update as an ISO file, extract it using the `geteltorito.pl` script, and write the extracted file directly to a USB drive using the `dd` command. The guide notes that tools like Rufus may not recognize the ISO file and that enabling Legacy boot in the BIOS may be necessary before the update.", "body_md": "- Creating the bootable USB stick was done with Mac laptop, but the instructions should work with any Linux OS.\n-\nDownload BIOS Update (Bootable CD) *.iso file\n-\nOn download geteltorito.pl for extracting the BIOS.iso file (the BIOS.iso name depends on the file you downloaded).
