DCU - Dasharo Configuration Utility

Introduction

The Dasharo Configuration Utility is a tool designed to configure Dasharo firmware binary images. It includes task such as customizing the boot logo, and setting unique UUIDs or Serial Numbers in SMBIOS tables. This README provides only the most basic information. For details please refer to documentation.

Prerequisites

Following packages must be installed:

• imagemagick (for convert command)
• util-linux (for uuidparse command)
• coreboot's cbfstool

Usage

Usage: dcu OPTIONS coreboot.rom

  coreboot.rom  - Dasharo coreboot file to modify

  OPTIONS:
    -u | --uuid <UUID>              - UUID in RFC4122 format to be set in SMBIOS type 1 structure
    -s | --serial-number <SERIAL>   - Serial number to be set in SMBIOS type 1 and type 2 structure
    -l | --logo <LOGO>              - Custom logo in BMP/PNG/JPG/SVG format to be displayed on boot

  Examples:
    ./dcu -u 96bcfa1a-42b4-6717-a44c-d8bbc18cbea4 -s D07229051 -l ~/logo.svg coreboot.rom

    ./dcu -u `dmidecode -s system-uuid` -s `dmidecode -s baseboard-serial-number` coreboot.rom
      Above command will obtain the current SMBIOS UUID and Serial Number
      from the system and patch the coreboot binary.
