Creating a (bootable) DOS floppy disk image

[T o n g]

Hi,

How can I make a DOS floppy disk image under Linux?

[OT]
Moreover, my experience with DOS was back in stone age when you use

sys A:

to make it boot-able. Now with Win NT/XP etc, I hear that merely copying
ntldr, ntdetect.com and boot.ini into it will make it boot-able. Anybody
know if it is true?
[/OT]

Thanks

I haven't made a dos disk in ages but I think mkdosfs from the dosfstools
package will do this.

Depends what you want to do with the floppy. I won't comment on
MS-Windows, but a single-disk FreeDOS floppy such as BALDER will
boot to FreeDOS with vfat but not ntfs.

There is the Freedos project for installing a DOS system, or the following might
be what you are looking for:

$ dd if=/dev/zero of=floppy-image bs=1440k count=1
$ /sbin/mkdosfs floppy-image

You need the dosfstools package for the latter command.

Thanks Sven, and every who replied as well.

Just for the archive, the '-C' option of mkdosfs can be used to create
the new file system in a file instead of on a real device, and to
avoid using dd in advance to create a file of appropriate size.
