OS/2 2.00 build 6H.177

OS/2 2.00 build 6H.177 is the official "Limited Availability" build of OS/2 2.0 from December 1991, and as such was officially supported by IBM alongside the General Availability (GA) build 6.307. System disks 1 and 3 were initially available as corrupt copies for an extensive period of time, and the full build with the recovered floppies was later shared onto the Internet Archive on 21 April 2022.
