Each computer would have its own distinct hardware and its own version of MS-DOS, a situation similar to the one that existed for CP/M, with MS-DOS emulating the same solution as CP/M to adapt for different hardware platforms. So there were many different original equipment manufacturer (OEM) versions of MS-DOS for different hardware. But the ...
MS-DOS 7.0 was included in Windows 95's first retail release. It contains support for VFAT long file names when run in a Windows Virtual 8086 box or with an LFN driver such as DOSLFN. JO.SYS is an alternative filename of the IO.SYS kernel file and used as such for "special purposes". JO.SYS allows booting from either CD-ROM drive or hard disk.
