{{Unreferenced|date=May 2020}} {{notability |date=October 2025}} '''ETen Chinese System''' (倚天中文系統) was the most popular [[DOS]]-compatible traditional Chinese operating system before Chinese [[Windows 95]].
DOS did not support [[Chinese characters]], which are not in [[Extended ASCII]]. Many companies in Taiwan developed their own [[IBM PC compatible]] traditional Chinese operating system running on DOS, which were mutually incompatible between the OS, such as Kuo Chiao (國喬) and [[Acer Inc.|Acer]].
The developer of the Eten OS, [[E-TEN]], earned their early profits from sales of their hardware based plug-in card based Chinese system products. Their software (only) Chinese systems were widely copied by many [[traditional Chinese]] users and [[software pirate]]s, but this was difficult for E-TEN to control. Most traditional Chinese products were compatible with the Eten OS at that time.
When [[Microsoft]] developed the Chinese [[Windows 3.1]] and Windows 95, traditional Chinese software developer and users shifted to Windows from DOS. The last version of the Eten OS was a Chinese Windows-compatible version. The Eten and other traditional Chinese OS are now used in a few DOS based [[Point of sale|POS]] systems.
