Implement int 2f ax=1600, which is, according to the Interrupt List,
used to check to see if windows 3.x if running. We always return 0,
which means that neither Windows 3.x nor Windows/386 2.x is running. It
also means, btw, that XMS version 1 isn't installed, which is true since
we don't implement that either.
