Hi Olusegun, if you go back as far as the DOS days, which I think you do, you'll remember that sometimes, it was necessary to put a disk in drive A before you turned your PC on, in order to perform certain installations. Even if you had two floppy drives, it had to be drive A. It's a similar thing here. When you perform an upgrade to the ROM of the BrailleNote mPower, you are not actually running KeySoft. You're running a stand-alone application so that no files are locked when we replace them. The mPower's hardware looks for the presence of these special files on the SD drive. SD cards were chosen because they are by far the cheapest media out there in terms of the range of media the BrailleNote mPower supports.
