+=== MS-DOS 1.25 ===
-This was the first version to launch with the [[IBM 5150]], or better known as the IBM PC.  1.0 'featured' a flat filesystem, and only supported the 5 1/4" [[diskette]]s,
+This was the first version of MS-DOS to be released to OEMs other than IBM with similar functionality. Some of the OEMs included Zenith, Eagle Computer, TI, and Sanyo.
-=== MS-DOS 2.0 ===
+=== MS-DOS 2.00, 2.10, and 2.11 ===
-I think this release added support for the [[IBM XT]] and hard [[disk]]s. [[Hierarchical]] filesystems were a new addition as well.
+This version supported 10 MB [[hard drives]] and on some systems such as the [[TRS-80 Tandy 2000]] and Toshiba T1100 Plus supported non-standard disk formats such as Quad-Density and 3 and a half inches floppy disks. OEMs included DEC Rainbow, Tandy, AT&T, and Wang.
 === MS-DOS 3.0 ===
-I think this release added support for 5 1/4" high density disks, and the [[IBM AT]], as well as came with a virtual disk driver with source code.
+This version supports up to 32 MB hard drive partitions and 1.2 MB high-density floppy drives. There we very few OEMs for this version including Apricot and Compaq.
 === MS-DOS 3.1 ===
-Added support for the NET command, and the Network re-director support both for server and client.
+Added support for the NET command, and the Network re-director support both for server and client. It became the minimal DOS version for any network based software.It had many OEMs including Compaq, Wyse, and Zenith.

 MS-DOS version 3.2 changed all this, but the reason a generic MS-DOS could be produced was that vendors had started to see the point of being truly IBM compatible.
 === MS-DOS 3.3 ===
-I think this release added support for the 3 1/2" high density floppy.
+This was the first retail version of MS-DOS. This release added support for the 3 1/2" high density floppy. I also recall this version being VERY popular... Even to the point where people avoided MS-DOS 4.00 to run this version. It added extended partition and logical drives. MS-DOS 3.3 also included some support for the FAT16 filesystem, however its format command still was limited to FAT12 filesystems. IBM (after a joint development agreement with Microsoft) was the main developer of MS-DOS 3.3, and PC-DOS 3.3 was nearly identical to the OEM version of MS-DOS 3.3.

-This was the first release to support logical drives & extended partitions. This was also the first time that Microsoft had sold MS-DOS as a retail product, which was a break from the traditional OEM channels that Microsoft had fostered.  I recall it selling for $50.  DOS 4 still included the ancient programs edlin(MS-DOS and PC-DOS) & gwbasic(MS-DOS).
+MS-DOS 4.0 could use partitions larger than 32MB.  I've seen it on 512MB disks, it may go up to the full limitation of FAT16 of 2GB. DOS 4 still included the ancient programs edlin(MS-DOS and PC-DOS) & gwbasic(MS-DOS).
 The first release 4.00 was VERY buggy, resulting in random disk file corruption, although I recall something about 'large' 32MB files and various other things.  Most people downgraded to 3.30.  4.01 addressed whatever issue it was, and it was good news. The update 4.01 was released less than 3 weeks after 4.00, but the damage was done.

-Also known as European DOS, or Multitasking DOS, this is the oddball outcast, rather it is a re-write of MS-DOS 2.1 to facilitate multitasking. It adds support for NE style executables, a task switcher, along with a few utilities to monitor the system.  Also included is the needed LINK4 NE linker for the OS.  So far no SDK or any real documentation has been found, although it is possible to build simple programs with Microsoft C 3.00 and link them with LINK4.  MS-DOS 4.00M served as the foundation to what was to become OS/2.
