No $PATH, but there is %PATH%.

Also, installing dos stuff in C:\DOS is what people generally did. I'm pretty sure it could be anywhere in the path.

I remember there being a PATH setting in either autoexec.bat or config.sys

Paths were set on Autoexec.bat, config.sys was for driver related configurations.

People not smart enough to edit Autoexec.bat apparently.
