Yeah no I'm sure you do, but you didn't read the comment, he's talking about the native INI-style syntax for boot menus baked into the DOS 6.0 kernel that allows you to specify multiple different CONFIG.SYS sections, and lets you pass an option to your AUTOEXEC.BAT containing the config name so it can finish the job off.

A must for anyone who ran a different config for different scenarios. I often ran without CD-ROM drivers to get a couple K more memory for the pickiest programs.

But not in this case, the menu system was not there on day 1.
