 Probably not. You're supposed to do it yourself, that's why it's homework / an assignment. Think about talking to your supervisor or classmates first. If you suspect a MINIX bug, verify it's present in the latest version and post details on how to reproduce it. Probably not.

 Write the USB image file to the USB device sector-by-sector (e.g. with //dd//). In other words, don't write it to a FAT filesystem on the USB device, but write the file to it starting at the first sector (Sector 0). This will, of course, effectively wipe all other information that was stored on the USB device. Write the USB image file to the USB device sector-by-sector (e.g. with //dd//).
