XFree86 is a port of X11R6.3 that supports several versions of Intel-based Unix. It is derived from X386 1.2, which was the X server distributed with X11R5. This release consists of many new features and performance improvements as well as many bug fixes. The release is available as source patches against the X Consortium X11R6 code, as well as binary distributions for many architectures.
XFree86/OS2 is the name of the implementation of XFree86 on OS/2 based systems.
See the Copyright Notice.
Binaries for OS/2 Warp, Merlin, and Aurora are available from: ftp.XFree86.org:/pub/XFree86/3.3.6/OS2
The WWW page http://borneo.gmd.de/~veit/os2/xf86os2.html will usually show more references to FTP or WWW sites to retrieve sources or binaries.
Other versions:
XFree86/OS2 will run on all dialects of Warp 3, including Warp "red spine box", Warp "blue spine box", Warp Connect, Warp Server, and Warp 4.
For Warp 3 installing fixpack level 17 or later is strongly recommended. There have been a few reports that the installation of FP26 causes XFree86 no longer to work, but I am not sure about a real reason. Current fixpacks for Warp 3, like FP36, seem to work well also.
Warp 4 may be used with or without the recent public fixpack.
Please check in all cases a LATEST.OS2 file.
OS/2 2.11 is not supported any longer with this release, due to lack of a working test environment. Consequently, OS/2 SMP 2.11 is not supported either. Warp Server SMP is supported, but SMP does not give significant advantage, other than the general speedup because of multiple processors working. OS/2 versions 1.X are definitely not supported and will never be.
It is possible to build XFree86/OS2 from the sources. Read about this in the document OS2.NOTES.
