Though I still don't understand why `ls -h' and also `du -h' display 1,40625 MiB as 1,5M and not 1,4M Anyway > *However* I have tried the image on another machine with a different floppy > disk (known to be good: at least it was carrying a file system before without > any errors). > > So different hardware, different floppy drive, different physical disk > with the same result: > > GRUB loadingRead Error > > Next I dug out a brand new floppy preformatted and tried again.

You could also try to install it the normal way with grub-install --root-directory=/mnt /dev/fd0 But first use mkfs.ext2 /dev/fd0 or maybe use minix or fat, they should take up less space. -- Felix Zielcke Proud Debian Maintainer -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
