'''DOS/V''' is a Japanese computing initiative starting in 1990 to allow [[DOS]] on [[IBM PC compatible]]s with VGA cards to handle [[Double-byte character set|double-byte]] (DBCS) Japanese text via software alone.<ref name="Boyd_1997"/> It was initially developed from [[PC DOS]] by [[IBM]] for its [[IBM Personal System/55|PS/55]] machines (a localized version of the [[IBM Personal System/2|PS/2]]), but IBM gave the driver [[source code]] to [[Microsoft Corporation|Microsoft]], who then licensed a DOS/V-compatible version of [[MS-DOS]] to other companies.<ref name="Boyd_1997"/> 

[[Kanji]] fonts and other locale information are 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 is in allowing compatibility with foreign software. This had not been possible under [[NEC]]'s proprietary [[PC-9801|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). In Japan, IBM compatible PCs became popular along with DOS/V, so they were often referred to as "DOS/V machine" or "DOS/V [[personal computer|pasocom]]" even though DOS/V operating systems are no longer common by the late 1990s.<ref name="IT_20160507" />

The promotion of DOS/V was done by IBM and its consortium called [[PC Open Architecture Developers' Group]] (OADG).<ref name="Boyd_1997" /> [[Digital Research]] released a Japanese DOS/V-compatible version of [[DR-DOS|DR&nbsp;DOS]] 6.0 in 1992.<ref name="ASCII_1992_DRDOS60V"/><ref name="Wein_2012"/>
