This is simply a side-effect of *all* PCx86 disk images provided by the PCjs website: a BPB is automatically
included in all disk images. This ensures that your modern operating system will be able to mount the disk image.
This is simply a side-effect of the [DiskDump](/modules/diskdump/) utility that's used to prepare disk images for the
PCjs website. It automatically adds a BPB to the boot sector if the BPB is missing or incorrect, making it easier for
modern operating systems to mount the disk image.
