Talk:Comparison of DOS operating systems

Regarding the question mark in the column, "Integrated disk compression utility?", for MS-DOS 7.1, it is my belief that MS-DOS 7.1 does offer DRVSPACE.BIN. I believe drive compression via DriveSpace is offered in Win95/98, but not for FAT32 partitions. Please don't consider me an authority on this. If you edit the page based on this, please verify it.

Changed title

I changed the title from "x86 DOS Comparison" to "Comparison of x86 DOS operating systems" on the grounds that it seems more consistent with other articles of this type. Unfortunately, "DOS operating systems" does suffer heavily from RAS syndrome, but "DOS implementations" doesn't seem better (because nobody says "DOS implementation"), and "DOS versions" doesn't feel precise enough (it could be misread as "MS-DOS versions", since "version" usually implies different versions of a single product). I also thought about whether it should be "x86" or "x86-based", but I don't think "-based" really adds any clarity, so I left it out. - furrykef (Talk at me) 02:12, 14 September 2006 (UTC)[reply]

Notes DOS 8.00 solutions

I added to notes section two tips for overcoming shortcomings of DOS 8.00 without modifying at least IO.SYS, and avoiding COMMAND.COM modification by using 4DOS (used at some time as NDOS in NU 8.00), and too minimal one-byte patch solution to COMMAND.COM from: http://www.edm2.com/index.php/RIPLing_Windows_Millennium_Edition Wikinger (talk) 15:09, 28 November 2007 (UTC)[reply]

Dos 2.x - Info missing

Any reason for that ?

Just a recap on the significance of 2.x, it introduced hard disk support for the 1st time, a big deal in the day. 10Mb limit, iirc. fat12, 16 ?

PTS-DOS

Was released at 1991 or earlear. At Middle of 1990-x years, it splits to 2 indepdent lines - PTS-DOS from Phystechsoft & PT$-DOS (spelled at russian as 'Pe-Te-Buks DOS' from Paragon. Due to migration of it's main developer (Garry Shumar) to Paragon, later extensions of this 2 lines were totaly incompatible. After some time PT$ DOS was renamed to Paragon DOS.

LDOS

I made an entry about the release of LDOS, which was simply awesome. See http://www.lists.ufl.edu/cgi-bin/wa?A2=ind04&L=linux-l&T=0&P=82159 and http://lists.celestial.com/pipermail/filepro-list/2004-December/005503.html and http://www.tim-mann.org/ldos.html . If this isn't appropriate here, please move it somewhere that it will be appropriate. Thank you. Svanslyck 11:50, 24 October 2007 (UTC)[reply]

PC-DOS

After the IBM-Micrsoft split, IBM decided to compete on the DOS front. IBM DOS 5.00.1 was the first DOS to be released to non-IBM machines. The readme in the IBM download 'dos5eiub.exe', explains how to convert an IBM-hardware-only upgrade into a general upgrade for any vendor's DOS. IBM 5.02 was released also for the OEM market too, appears to be all of the previous fixes amd tbe utilities 'INTERLNK/INTERSRV' added. IBM 5.02 dates are (ymd) 1992.09.01

A product which the manual calls "IBM DOS 6.0", but the readme calls "IBM DOS 6.1", was released with file-dates 1993-06-29, time 12:00:00. This is a four-diskette layout, that was packaged in the same manner as DOS 5 (even down to the same Windows icon). It supports the MS-DOS dblspace.bin compression interface, but has no compression itself (this was available by coupon).

The PC-DOS 2000, is actually version 7.00A, not 7.01. This appears mainly to be the assorted PC-DOS 7 files, slip-streamed into PC-DOS 7.0, and sold on six 1440k disks, rather than 1 1440K + 4 XDF. By the time of this release IBM had already exited the DOS market, and both PC-Company and Boca Raton (the home of DOS) had ceased to exist.

IBM has also "released" PC-DOS 7.10, which appears as a boot-disk only DOS (like that of DR-DOS 7.04/5). This is based on the 7.0 source, but with support for FAT32 (but not long file names). Norton Ghost uses this to build floppies. At least four different builds of this have been seen. According to IBM's documentation of this, Microsoft's FDISK of Win98SE vintage runs under it.

I added entries for PC-DOS 6.1, 6.3 and IBM DOS 6.0 to the tables. --Wendy.krieger (talk) 09:34, 2 April 2008 (UTC)[reply]

End of hardware-dependent MS-DOSes

MS-DOS was originally released by OEMs for a number of different, incompatible x86 machines. At some point all versions collapsed into a single IBM-compatible version. At some point, probably the same point, MS-DOS became marketed only by Microsoft, I think (not sure). If someone knows when these things happened they're worth adding. Was it DOS 3?
