OS/2 2.00 build 6.123

OS/2 2.00 build 6.123 is a beta build of OS/2 2.0. It is the February 1991 beta of OS/2 2.0. On 2018-07-10, Michal Necasek from the OS/2 Museum blog was able to gain a copy of this build. On the surface, this build is still very similar to IBM OS/2 1.30.2, although it contains a darker color scheme. Internally, the kernel has been ported to the i386 (32 bit) protected mode: most notably, this allows running multiple DOS boxes, which wasn't possible in OS/2 1.x.
