In the documentation for the 【MS-DOS 7.10 Super Boot Disk】, it says:
1 - You can choose the boot method at startup (Bootable media selection on boot)
========================================
Through the famous free and open multi-system manager GNU GRUB and other tools, as well as the related
configuration work I did on them, this boot disk can let you choose at startup whether to boot the system
from this boot disk, the hard disk, or even the CD.
That way, you can keep this boot disk in the drive all the time, and use it to choose whichever boot
method you want. Also, even if the system BIOS does not support booting from CD, this boot disk can truly
make booting from a bootable CD possible.
But when I actually made one, there was no such choice as above. What is the reason, webmaster?
