I am trying to make a floppy image with a working file system so that I can test a 2 stage boot loader. When I attempt to mount the floppy and then cp the second binary over to it, mount gets all unhappy. Here are the steps I am trying to use:
dd if=/dev/zero of=floppy.img bs=512 count=2948
mkfs.vfat floppy.img
dd if=boot1.bin of=floppy.img bs=512 count=1
[Code]....
I am trying to write a floppy boot image to my floppy drive (as root):
Code:
dd if=boot.img of=/dev/fd0
dd: opening `/dev/fd0': Read-only file system
[code]....
I'm developing my own OS, but I'm having some problems with Qemu, because I need to change the floppy image from grub.img to os.img while the emulation is running, but how can I do this?

Virtual Machine: Bochs-2.4.5
I want to learn some details about linux booting, so I begin writing a small boot program myself. Yesterday, I was writing a small boot program and planned to use it boot a Bochs virtual machine. The boot program is written in assembly language and compiled with nasm.I use bxiamge.exe in Bochs and create an floppy image called boot.img and configure the Bochs virtual host to boot from this floppy image. My question is how to write the compiled boot.bin program into the floppy image(boot.img)?
I have a list of files that I am copying around for various purposes. What my current command looks similar to this:cat list_of_files | xargs -I {} /bin/cp -f {} /destination/dirI am using the full path to cp so that the default alias of cp -i does not take effect. However, when I find a duplicate file, it is overwriting any that have already been copied. What I would like to do is to force cp to not overwrite and not prompt.

dd bs=8192 if=Image of=/dev/PS0
In the above command, I cant able to understand the option "of=/dev/PS0"
Whether it means,
1) to write the input file "Image" in to "/dev/PS0" of the Floppy device
or
2) to overwrite the same input file "Image" in a file format ("/dev/PS0") of Floppy.

I am having a Promise TX4650 RAID controller & trying to create a driver floppy for installing the drivers. Also am using RHEL 5, I can create the driver floppy, but when I type "mount /dev/fd0 /media/floppy" I get error: "mount: mount point /media/floppy does not exist".Can I get the files in a format other than the ext2 floppy image, so that we do not need to use a floppy drive?There is a readme file inside the driver archive & you can use that as a reference.

Is there any way I can make mkdir silently overwrite any existent directory? (no messages in the output). For the same price, could it be done with other commands such as cp or mv?
I have a USB drive on which I want to install Arch Linux (using the installer, not unetbootin or something similar, as I want the drive to be persistent.) The computer from which I want to boot this USB supports booting from a USB floppy, not a normal drive. Is there any way for me to make a USB floppy on another drive and use that to boot the normal USB drive?

View 3 Replies View RelatedI have a couple of directories that I want to turn into an image. For example:
Quote:
/usr/dir1
/usr/dir2
I want to end up with two imgs (dir1.img and dir2.img). I wanna be able to type in:

mkdir /usr/dir1
mount dir1.img /usr/dir1
How can I do that? If I can't use mount than what should I use?
Not sure if anyone uses floppy drives anymore much. I know that most machines don't come with them anymore unless you ask for one.One of my machines [Machine # 2] has a floppy and I have never had the occaision to use it under linux [opensuse 11.2 currently]. Until now that is! I have about 30 floppies that I need to transfer the data from. I am able to mount the floppy drive and take data off the currently inserted floppy, but if I want to insert another floppy and remove the data from it, I must unmount and remount the floppy everytime. There is an entry in fstab:
/dev/fd0 /media/floppy auto noauto,user 0 0
and a mount point in media [/media/floppy] Is there something else I need to have in the fstab line for the floppy so that it will read automatically everytime I insert a disk?

View 1 Replies View RelatedIs there something weird about the FLOPPY DRIVE on F12? Nothing associated with it works & I can't get an icon for it. Also the FLOPPY FORMATTER no longer works. (mine is an internal drive)- I had some really miner quirks with it in 10 but it worked. I had some workaround launchers that I used until an upgrade semi-fixed it. (It would give a false error that it couldn't run but did. I just ignored it.)
I tried to edit FSTAB to cure a problem of my BACKUP drive showing up twice*** so while I was in there I added the stuff for the floppy & it still doesn't work. If I try to mount it manually, I get the error that /dev/fd0 doesn't exist.I tried to find some info on it & it SEEMS that there MAY be a bug but I'm not sure as the info is a bit confusing as to just what version & such they are talking about. And there was also the problem that all the stuff seemed to be OLD or not related to my problem.I why I quite hacking at my system, is that all my workaround launchers & the formatter say that there are GNOME things missing & they can't run. So I figure that there is something missing or screwy already & that I'd better ask BEFORE I make things worse or actually break something.With the fact that floppies are about gone, it's getting to be not that big of a deal but I still find myself having to use them for repair purposes (albeit, not as much) & it gets to be a bit of a pain to fire up M$ just to do something like this.
*** It appears that the one in FSTAB was the one I needed, so where would the OTHER one be so I can get rid of it? Or at least make it auto mount.
I have never used rsync before, only DD. But from what I have been reading, rsync is better becasue it will basically mirror your hard drive, thus being able to run the cloned software from the new hard drive. My problem is I do not know what is the best commands or even the basic commands to use in rsync. I am trying to make an image from a external hard drive to a usb drive. That way my chances of messing up he original software is not as risky becasue I'll just restore the image onto another hard drive. Does anyone know the best script to have rsync make an image file of a hard drive and place it on a usb drive and then restore it?

View 3 Replies View RelatedI have a Debian OS installed (6.0), installed on a single partition, which was running out of space. So I copied all the data in /home to a spare partition, then edited fstab to mount this new partition as /home.
This works fine. But now of course I have the /home data both on the new partition (the one that is now being mounted and used), and also still on the original partition, though this directory is no longer mounted by the OS, so I can't directly 'get at' the data to delete it.
I could easily get into the partition from another OS and delete the unneeded /home data of course but I was just wondering; as this data is no longer 'seen' by the OS, will it be overwritten automatically by the OS when it needs more space, as it does with data that has been deleted from the filesystem, or would it be reserved somehow, still using up space?
