Upgrading crucial M4 SSD firmware from grub2

Tuesday, October 28th, 2014

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!

BluOS 1.12.0

Friday, October 17th, 2014

A new BluOS for my Bluesound. Version 1.12.0 brought Murfie and HDTracks support. And I almost trashed it in my attempt to gain root on the device after the upgrade. They have a bad habbit of shutting me out ūüôā

Barrier Breaker on my Linksys E3000

Wednesday, October 15th, 2014

I finally got the time after the release of Barrier Breaker to install it on my Linksys E3000. I have been really happy with the Tomato USB by shibby that I installed back in february.

TomatoUSB is a lean mean router distribution, actively developed and work really well. So why did I switch then? To a less polished, more do it yourself router? Mainly due to the fact that it turns my router into a generic linux distro. It gets more versatile. I can install whatever I pleases. At the cost of ease of use. An ok tradeoff when you are an fulltime Unix administrator at work.
