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.

PC-DOS 1.10 was released in May 1982 on one single-sided (160Kb) diskette. A complete listing of all the files
is provided below.
Also, in case you're wondering why 1920 + 6400 does not equal the "8704 bytes in 2 hidden files" reported by CHKDSK,
that's because all CHKDSK byte totals are cluster-granular. On a 160Kb diskette, 1 cluster equals 1 sector or 512
