The sector material loaded at 0000h:7C00h constitutes a VBR now. VBRs are operating system distinct and can't be exchanged among diverse DOS variations generally, as the precise behaviour differs in between different DOS versions. In very aged variations of DOS which include DOS one.x, the VBR would load The full IO.SYS/IBMBIO.COM file into memory at 0000h:0600h.[thirty] For this to work, these sectors had to be saved in consecutive get on disk by SYS. In later problems, it could locate and store the contents of the first two entries in the basis Listing at 0000h:0500h and whenever they transpire to reflect the correct boot data files as recorded while in the VBR, the VBR would load the very first 3 consecutive sectors from the IO.
