v2.1.657 - File Info function updated to display boot sector info

If you use Drive Info in RMPrepUSB to read sectors from a disk, if it is recognised as an MBR or PBR, the internal values will be parsed and displayed for you in Notepad. However, the File Info function in RMPartUSB only displayed MBR values if it detected a valid MBR but did not display PBR values. v2.1.657 fixes this. Now you can use File Info to display the hex data in a bootsect.dat PBR file, for instance, and it will parse the BPB for you - e.g.


COMMAND LINE: FILE="F:\bootsect.dat" FILEINFO FILESTART=0 SURE
