First firmware update via Ubuntu applied to the work Lenovo. Went off without a hitch! Bye bye, USB 3.5" floppy drive!
Yes … I have a 3.5" floppy drive with a USB connector from an old IBM ThinkPad T43p. The notebook itself is long gone, but I kept that particular accessory "just in case", and it's been used at least once every year to apply firmware updates to various machines that are not allowed to run Windows.
Remember when computers looked like this?
