What is a "simulate floppy disk?" If you bios is set to boot floppy first in the sequence, you can boot from a bootable floppy before the hard disk, which is where the grub bootloader is located.
Assume that, my bios is set to boot floppy first in the sequence, at the booting time, in fact, there is no floppy disk in the floppy device, however, the machine would consider there is a floppy disk (I call it a simulate flopp disk), and I could config what files in the harddisk would be considered as the files in the simulate floppy disk by the machine. Could I achieve this?
Thank you.
Probably missuderstanding but it would be easier to just put an alternative menu in grub's menu.lst and choose that on startup. Perhaps change runlevel 4 and boot into that.
allright, an image from a floppy on your harddisk doesn't get bad sectors as fast as a floppy dos, so thats correct.

I think in some cases, for example, grub cann't be used, mbr is not very good, the floppy disk is useful.
OK, when your MBR is damaged, you use a floppy. But to use a simulated floppy, that is, to boot a floppy image form your harddisk, you will also need your MBR on the harddisk, so in that case a simulated floppy disk wont do you any good.

Yes, I am in Kunming. They have answered your questions, I believe. Perhaps it would be best to have a floppy sometimes. If you are concerned about the data on the floppy being damaged, you could burn a boot image to a CD that would boot before grub. That would be okay if the floppy was bad. I use a bootable Win98 disk a lot of times working on Windoze computers.
Sorry that I cannot help you. Wo bu zhi dao freedos. I do not know of any operating system that NEEDS to boot from a floppy. Also, there is a lot I do not know. I hope you can get what you want. For me, what I want is not to ever boot any Micro$loth operating system for the rest of my life.
