Upgrading crucial M4 SSD firmware from grub2

The download page for firmware for the Crucial M4 SSD have three options

  • One for windows 7
  • One for windows 8
  • One generic .iso for mac and windows

Lets for arguments sake think that someone have an x200s (no cdrom) with linux, then what? Actually not that hard:

sudo mount -o loop crucial-m4-070h-07-00.iso /mnt

sudo cp /mnt/boot/isolinux/memdisk /mnt/boot/isolinux/boot2880.img /boot/

sudo umout /mnt

sudo vi /etc/grub.d/40_custom

menuentry ‘Firmware Upgrade’ {
linux16 /memdisk floppy raw
initrd16 /boot2880.img
}

sudo update-grub2

sudo reboot

<hold shift for grub2 menu>

select ‘Firmware Upgrade’

Non-disruptive in my end, going from 0009 to 070H, but if you break anything, I will yell unicorns at you and let you keep the pieces. Because a crazy dane decideds to do this without backup, you should not do the same!
