Crucial is selling many good ssds, and frequently releases new firmware.  
When you have to manage many version of these ssds, it is really time consuming to keep them up-to-date.

‘crucial-fw.pl’ is a little script to generate a single grub config for any crucial ssd firmware upgrade.  
It’s a perl script.

```
LWP::UserAgent
File::Copy
Archive::Extract (debian like: apt-get install libarchive-extract-perl)
Archive::Zip (debian like: apt-get install libarchive-zip-perl)
```

‘crucial-fw.pl’ generates a file for grub (default is /etc/grub.d/45\_crucial-fw).  
Depending on the iso file, it will switch between two loading mode and grab the isolinux.cfg if needed.  
This configuration is creating a submenu entry for grub containing one menu entry for each ssd reference specified in the configuration.

Your linux kernel must be able to mount a loopback iso file (loop and isofs modules). Any vanilla kernel is.

You need to run: 'update-grub2' and reboot to apply one FW now

You can comment anything you don’t need.  
If Crucial is releasing a new firmware, you will have to refresh the url.

The files we are interested in are “Manual Boot File for Windows and Mac”.

Since these isos are using isolinux … an unfair nonsense.  
Why didn’t they add “and Linux and BSD and everything x86”? or simply put “for PC and Mac” (another possible nonsense since a Mac is a classic x86 hardware platform).
