"This is part of 3 drives that you may need if you have a legacy system and are trying to insert a flash drive into USB. The three files are USBSTOR.SYS, usbmphlp.pdr, and USBNTMAP.SYS.I downloaded all three and onto floppy. just choose browse when asked and install from floppy, flash drive will work great."
