Explanation what happens there:
Screen 1: first, there were only a few devices: ata in various forms, and memdisk second (an invisible step), I added the usb device (usb_add disk:img) third, I ran lsusb, which is currently responsible for device probing
Screen 2: I ran ls again, and yay, there are (usb0) and (usb0,1) (disk&partition)
Screen 3: Let's see, what's on there: (usb0,1) is of type FAT, labelled FREEDOS9RC5 It contains the various files shown above
Screen 4: Let's take a look into autoexec.bat
Thank you, Patrick!
This is excellent work.
