Whether after PC boots up the floppy just pressing "c" to start a
console. Then what will be next steps. Would it be similar to
starting grub, the bootloader, during booting HD?

Whether copy all files to /boot/grub/ on the floppy?

Shall I delete "(hd0) /dev/sda"
and add;
(fd0) /dev/fd0
In my case "dev/fd0" is the floppy drive.

I suppose doing it on console (Konsole if on KDE) after "su -". To run
grub just type;
# grub [Enter]
> root (fd0) [Enter]
> setup (fd0) [Enter]
> quit
If I'm wrong please correct me. Tks.
I suppose no change will be made on the HD. I still don't have a clear
picture how can the OS (FC5_64 in my case) on HD be started after
booting up the floppy.
TIA
