I'm mass-producing a USB flash drive. I want to use grub4dos to boot the system. Booting by loading dos.img works normally. I thought .IO.SYS is the DOS entry point, so having grub4dos load IO.SYS should work.
So I put IO.SYS COMMAND.COM MSDOS.SYS into one directory, and then had grub4dos load IO.SYS. I wrote it like this:
title DOS
find --set-root /io.sys
chainloader /io.sys
It really can enter DOS. But then this prompt appears:
Type the name of the command Interpreter (e.g.,C:\windows\command.com)

Is the menu.lst syntax wrong? Or can it only boot from an img image... and not from scattered files`?

io.sys, command.com, and msdos.sys must be placed on a floppy or hard disk image, and cannot be put directly inside a CD, because DOS does not support direct non-emulation booting from a CD.
