Ran into an issue where we had to flash upgrade some firmware in a server. As usual, firmware downloads came as MS-DOS programs, and told you to put them on a bootable DOS floppy disk and boot from it. This is becoming a real pain in the ass — who actually uses that Microsoft crap anymore? :) Also, what server has a floppy drive?
So, we improvise. Grab this [FreeDOS boot disk](files/boot.img). Mount in Linux:
sudo mount -o loop boot.img /mnt
Copy whatever files were provided by the vendor (hint: unzip handles most Windows self-extracting .exe’s) into /mnt.
