The "Checksums calculator" is an open source GUI application that has been developed to run on Windows, MacOS X and Linux operating system on 32-bit and 64-bit architectures. It calculates checksums of functions: md5, sha1, sha256, sha384 and sha512.
The Checksums calculator is an open source tool used in the following procedure and it is one of the many other tools available for customer use. Ribbon does not provide or distribute this tool for download. Ribbon makes no warranties on using this tool etc.
Perform the following steps to calculate the md5 checksum of the downloaded BMC firmware package and validate it against the value in the .md5sum file:
Download the calculator application (.zip) file that matches the version of your computer operating system.
Launch the "Checksums calculator" application from this folder. (The Checksums "hash" calculator name is different depending on your operating system).
The following images are for example purposes only and may not reflect the most current release version.
Using the Checksums calculator, browse and select the bmc5X00_xxxx.rom
file (where xxxx is the file version).
Select the "Hash function" md5.
Click Calculate. This extracts the checksum from the .rom file. A hexadecimal value appears in the Checksum text box.
Using a text editor, browse and open the bmc5X00_xxxx.rom.md5sum file (where xxxx is the file version). This file contains a hexadecimal checksum value.
Copy and paste the contents of this file into the "Original checksum" box.
Click Compare.
The validation is successful when both checksums are same and a message box displays "Checksums are identical".
If any other message displays, repeat the process to download both the .rom and .md5sum from the Ribbon Support Portal and repeat the checksum process. If the validation fails a second time, contact Technical Support.
The example here shows the validation of BMC firmware package with the md5sum. The procedure is also applicable to validate checksum of BIOS, OS and SBC application packages.
