Lenovo does not seem to provide laptop firmware updates for linux. Laptops tend to lack a dvd drive lately. How do I update under Linux/Unix?

Here's what a colleague shared recently. Thought it might be useful to a wider audience. Marking as a community wiki as I don't share credit for it. Procedure might work for other laptop makes I guess.
- Visit the driver matrix for your T460p on support.lenovo.com and download the image of the "BIOS Update CD for Windows 10". (I ended up getting the version for dos But I don't think it really matters)
- If not already installed, install genisoimage and geteltorito:
yum install genisoimage geteltorito
- Extract the El Torito boot-image from the downloaded *.iso-file,
- in my case that is
r07uj12wd.iso: geteltorito -o bios.img r07uj12wd.iso- Find out the block device name of your USB flash drive:
lsblk(e.g./dev/sdb)
- in my case that is
- Write the extracted image to an USB stick. In my case it is the USB (I had a old 1G laying around I used) stick is attached as
/dev/sdb:dd if=bios.img of=/dev/sdX bs=1M status=progress ; sync- Boot from the USB stick and follow BIOS upgrade instructions
I did this on my t420s And it worked with out a problem
Attention: the above dd command is very dangerous as you can wipe out important data in case you choose the wrong device name. That's why I've put X in place of letter there - to avoid careless copy/paste troubles. Proceed with care!
