S3 drivers

 * Upon using S3 video adapters, Windows will complain that its own drivers will not work properly, thus the display will be stuck at . This error will also appear upon every boot and other drivers cannot be installed correctly, meaning that S3 video adapters are not recommendable for this build.

Neptune reference
A total of 9 files with the version number 5.50.5116.1 and 5.50.5117.1 were found in this Windows Me build, but it is unknown whether this Neptune build ever existed.

Some speculate this would've been a Milestone 2 build. It would've been compiled someday after 11 December 1999, meaning it would be one of the last Neptune builds before the Neptune project was canceled in January 2000.
