Updating linux lenovo
Since the beginning of this year, I'm a happy Lenovo Think Pad T440 user.All components are supported on Linux (currently running Ubuntu 14.04 on it) — everything Just Worked "out of the box" after the installation.
Installing Linux via an USB stick was a simple affair, it most cases you can simply download and the ISO image on the USB stick and select it as the boot device on the next reboot by pressing F12 at the right moment. But I do not see any reference for the same kind of ISO image for the Yoga 3 Pro. BIOS available on their website is the one I mention from 2013. I've had a dig around and the only way I could think of to do this would be to run Windows as a virtual machine, as you can't run it from USB or disk live as far as I know (but I could be wrong), and run the BIOS update from there. My next question is this: the Yoga 13 looks like it was released in 2013 and the last BIOS update I found is from January of that year. There is a BIOS update bootable CD ISO image for the Thinkpad.You then have one of several options: create a floppy, create a dd floppy image, create a user-installable distribution-specific package (e.g.RPM), or actually install the image for your bootloader.Flashromis a utility for identifying, reading, writing, verifying and erasing flash chips.
It is designed to flash BIOS/EFI/coreboot/firmware/option ROM images on mainboards, network/graphics/storage controller cards, and various programmer devices.
./BIOS ist ein Unterordner im aktuellen Ordner der von cabextract erstellt wird, um die entpackten Dateien abzulegen. die Option -d komplett weggelassen werden, um die Dateien an anderer Stelle zu entpacken.

However, this ISO-Image does not boot from an USB stick directly, so the dd method does not work.
Fortunately, like many times before, the Think Wiki came to the rescue — their page about BIOS update without optical disk gave me the right clues.
However, not having Windows installed on another partition and not owning an external CD-ROM/DVD-drive, I now faced one problem: how to update the BIOS?
