Microsoft MS-DOS OEM Adaption Kit (1987) 2 DOS

The Microsoft MS-DOS OEM Adaption Kit is a set of source code and binary object files used by OEMs to add custom hardware support. Such hardware support could range from simple hardware add-ons to completely non IBM-PC hardware compatible x86 machines. By the time of MS-DOS 3.3, the market had mostly settled on generic IBM PC hardware clones that would run "vanilla" MS-DOS distributions. MS-DOS 3.2 was the first DOS version to have a true retail "vanilla" release.

Microsoft Windows Boot Disk (1995) 525 DOS

These disks are original boot floppy disk media for use with Microsoft Windows CD-ROMs. Not all Windows 9x/ME CDs are bootable, not all CDs included boot disks, and DOS will not see a CD-ROM drive unless a driver is loaded. OEMs were expected to provide compatible CD-ROM with the boot media provided with their systems. However towards the very late 90s, most vendors standardized on IDE/ATAPI CD-ROM hardware and the use of the OEM Adaption Kit (OAK) driver. If your CD drive is not IDE compatible (such as an MKE or Panasonic interface) you must manually add your own driver. Note: you can use the Windows 98 boot disk with Windows 95 to make things easier. If you have any UNTOUCHED OEM boot disks with different drivers, please submit them.

PC-DOS (1981) 234 DOS

IBM PC-DOS was an IBM branded version of MS-DOS licensed from Microsoft for use on the IBM PC system. Versions of PC-DOS paralleled that of MS-DOS up until version 6.1, where PC-DOS was independently maintained by IBM up until 7.1, the last version. Although not the only OS available for the IBM PC when it came out, it quickly became popular due to its low cost in comparison to the others. Its direct competitors on the PC at the time were CP/M-86 and UCSD p-System. The major differences between PC-DOS and MS-DOS were only in terms of driver support and built in programs until version 6.1 where development diverged.
