Can I make a usb flash be detected and act like a floppy in windows?
Possibly without grub4dos and more like dd, fdisk or rmprepusb tools.
I am certain this is possible in a hardware way by manipulating controller chip and rewrite its memory, and I wanted to know if it might be possible by software.
Obviously, simply dd'ing the floppy image to usb doesn't work.
You might want to say to use a floppy disk. I know how a floppy disk looks, but given the notebook manufacturers consider it out of spec there might be some usb way, since we have usb ports.
You might ask why I need this? For flashing bios recovery under dos. There is a recovery bios key combination
( fn +b + power)which when pressed attempts to read for a floppy or usb containing the bios to write and other dos tools.
One problem that I might be encountering is using 32 gb usb formated with a partition with 1 gb for using fat filesystem.
And I need to disassembly more the recovery part from the bios in order to find the filename...
