Are you trying to mount the floppy before you use the dd command
to put grub files on it? You don't need to mount the floppy to write
to it. Also, you can't mount a floppy unless it has a file system on it.
Have you tried it with a floppy known to have good linux files on it?
You can test that way to see that you don't have problems somewhere
else, like maybe you forgot to compile floppy support into the kernel.

if i want to change the permissions of /dev/fd0 from

-rw-w--w--

to
brw-w--w--

how do i do it

also i did provide floppy support during kernel compilation.

If you had used the mknod command to make fd0 it should
have stuck the "b" in there for you. Here's an example:
mknod -m 660 fd0 b 2 0 ; chgrp floppy fd0
That's the command I used to make fd0 on my lfs 5.1
system. I don't know how the latest lfs is doing it.

i have run the above command on root and it created a block fd0 there so i changed the entries in /etc/fstab as follows:

filesystem /fd0

mountpoint /media/floppy

type auto

option noauto,owner,kudzu

dump 0

fsck order 0

so when i tried mounting the floppy as mount /media/floppy i get

mount: wrong fs type, bad option, bad superblock on fd0,
or too many mounted filesystem.
please help!!!

Do you have a floppy disk in the drive when you
try to mount it? Is it blank or does it have files
on it? It has to have a file system on it in order
for it to mount.

sharmashikha · 06-22-2005, 02:15 AM

yes there is a floppy in the floppy drive and it has file system mounted on it.
i formatted the floppy before using it for this purpose.

I understand your frustration. I spent several hours trying to
get the floppy to work on my own system. I ended up having
to put the mount command in a boot-up script so it would mount
it for me as a user at startup. Here's what my fstab looks like:

/dev/fd0 /media/floppy auto users,exec,rw,sync,noauto 0 0

and to mount it on startup I run "su - terry -c 'mount /media/floppy'
in a boot script. terry is my user name.
I presume you are trying to mount it as root?
If it doesn't mount when you are root then I'm about out of ideas.

How did you format the floppy? Have you tried doing a
mke2fs /dev/fd0
on the floppy in the drive?

sharmashikha · 06-22-2005, 03:19 AM

i think the major problem is that when i do ls -l in /dev directory it shows

-rw-r--r-- 1 root floppy 100818

against fd0.it is not showing it as a block device.

i don't know how to rectify this.

the floppy has been formatted correctly.

teryc · 06-22-2005, 03:42 AM

Sorry I can't help you more. I seem to have run out of ideas.
I'm using lfs 5 and I think lfs 6 does the devs differently using
"udevstart" which is not used on lfs5. You might want to go back
to chapter 6.8.2 on populating /dev and see if you forgot something.

thanks a lot neways.you'v been very patient.

Well, that means you're trying to mount it as the wrong filesystem. What did you format it as and what are you trying to mount it as (i.e. what's the line on your fstab for floppy say)?
