Yes. One fw_cfg "item" (for lack of a better name) chooses between 0 and >=1, the file gives the actual timeout. > If so, what is the default value of this fw_cfg file?

Yes, the default is zero. However, you would get to a shell on an otherwise unconfigured system, and you could enter the boot menu via OsIndications. It's what SeaBIOS does, and it is not very much different from what you'd do for machines you don't have physical access to.
