Does OS/2 Warp support Windows VxDs?
No. OS/2 Warp Version 3 does not support VxDs (or, more precisely, VxDs which compromise system integrity are not supported). Microsoft is actively discouraging use of VxDs (because applications which use them cannot run under NT and may not run under Windows95), and IBM recommends that you not invest in software which requires them. Most software vendors will probably be releasing updates of their products which do not use VxDs (or native OS/2 Warp versions of their applications). Fortunately, the number of applications which require VxDs is very small, and, of those applications, most are related to networking (for which there are most often superior native OS/2 alternatives).
