DOS/V was a Japanese computing initiative starting in 1990 to allow DOS on IBM PC compatibles with VGA cards to handle double-byte (DBCS) Japanese text via software alone.[1] It was developed by IBM for its PS/55 machines (a localized version of the PS/2).[1] Kanji fonts and other locale information were stored on the hard disk rather than on special chips as in the preceding AX architecture. As with AX, its great value for the Japanese computing industry was in allowing compatibility with foreign software, this had not been possible under NEC's proprietary PC-98 system, which was the market leader before DOS/V emerged. DOS/V stands for "Disk Operating System/VGA" (not "version 5"; DOS/V came out at approximately the same time as DOS 5).

The promotion of DOS/V was done by IBM and its consortium called PC Open Architecture Developers' Group (OADG).[1]

Notes[edit]

  1. ^ a b Japanese and Korean issues of the DR DOS ANSI.SYS driver contain support for a number of special arguments to switch to Japanese video modes and toggle between Korean and English input modes.
  2. ^ A Japanese version of Novell NetWare Lite named "NetWare Lite 1.1J" existed. Updates were distributed by Novell as DOSV6.EXE, DOSV.EXE, TSBODI.LZH.
  3. ^ A Japanese version of Novell DOS 7 was announced and is referred to in various English documents, but was apparently never released.
  4. ^ A Japanese version of Novell Personal NetWare 1.0 named "Personal NetWare J" existed, f.e. as distributed by CONTEC for PC-98 and DOS/V platforms. Updates were distributed by Novell as P10J0?.EXE (with ? replaced by 1 - 5), PNDOSV2.EXE, PNDOSV1.LZH.
