Windows Neptune build 5094.1
|Build of Windows Neptune|
A file, namely
opl3sax.sys, with version number 5.50.5094.1 can be found in Windows Millennium build 2416, but it is unknown whether this Neptune build ever existed.
Some speculate this could be a late Milestone 1 or an early Milestone 2 build. Judging by the file dates, it would have been compiled before 1999-11-11.
