Right? The reason why I'm asking is because I have this other PC and I'd like to use the same kernel on it.

Nope, sorry :( The m<whatever> commands only work for DOS formatted floppys. Your best bet is probably copying it off the original computer onto a formatted floppy and copying it off that floppy. I had thought that you could 'dd' it off the floppy, but that wouldn't work, because it would take an image of the whole floppy. Other ideas anyone?

Yup, that would be right if it was made by something like 'make bzdisk' or the like.

I' trying to mount my boot disk but I don't know exactly which filesystem I need to use as an option. By the way, is there a listing of every available filesystem somewhere in the documentation?

Right then, how did you copy it onto that floppy in the first place? 'dd', 'make bzdisk', 'cat', 'cp'? If it was one of the first three, you're pretty much stuck, since to get it off using 'dd' or 'rawrite', you would have to know the exact size of the kernel, or else you'ld just take an image of the entire floppy disk (since they won't know when to stop copying). If you used 'cp', the floppy will have a filesystem on it, which brings us back to your original question... ;-) So how did you make this disk?

Use cp (or mcopy) to copy it to the other computer, then use 'lilo' to install it. Don't forget to edit '/etc/lilo.conf'. If this is the first time you are playing with lilo, first create with lilo a bootdisk on a floppy (boot = /dev/fd0). That's a good excersise and you can only 'destroy' a floppy, not your HD. Before any big change, I always copy 'lilo.conf' to 'lilo.conf.fd0' and with 'lilo -C /etc/lilo.conf.fd0 -b /dev/fd0' I try it first on a floppy.

Hello, Yatsen! I don`t think, it would help, but just a note: Try to copy /dev/fd0 file (or /dev/fd1, if that`s your secondary floppy) to different name, onto your harddrive. And then try to mount that file instead of a device. Don`t forget to add "-o loop" switches to "mount" command. Anyhow, if you can do nothing with that floppy, you can upload that file to someone, who will dig it precisely. I bet, I can detect most of filesystems, using just hexviewer of MC.

Did you use 'cp /boot/vmlinuz /dev/fd0' or something simulair as root?

Yes

If you did this, you destroyed your filesystem on the floppy. There is no way to mount it...

I'm surprised to hear that - I didn't know about this. However, it sure explains a lot! Why does this distroy the filesystem? I thought this was the way it should be done.

If you feel lucky (maybe, I never tried this...) you can copy the file with 'cp /dev/fd0 vmlinuz'.

In the future, use 'mcopy' to copy a file to a floppy. You can do this as a normal user.

Now I'm confused. Someone mentioned before that mcopy is only used to copy files off a DOS formatted device (in this case a floppy).

Good luck, Cees.

Under Unix, everything is a file. You probably know that you can print with 'cat [file] > /dev/lp0'.

In the same manner you can copy a complete floppy to a file: 'dd if=/dev/fd0 of=/tmp/floppy', an image of fd0. To copy this image back to floppy, you can use a command like: 'dd if=/tmp/floppy of=/dev/fd0'.

You can even mount this image under Linux. (I don't know if this is true for all Unix-es.) Try: 'mount -t vfat -o loop,ro /tmp/floppy /mnt/tmp' and you can use this image as a mounted floppy!

(I do this a lot with CD's. If you mount them and them copy them, you don't copy the boot-sector, with the dd-methode, you make an exact copy.)

Even so, a floppy is not 'a normal' file of 1.44MB. It is formated, has entries for directories, etc.

So, if you copy a file to /dev/fd0, it first overwrites record 0 (the MBR with all the formatting information), next record 1, etc. You get the idea...

With other words: you destroyed all formating information!

Now I'm confused. Someone mentioned before that mcopy is only used to copy files off a DOS formatted device (in this case a floppy).

You shouldn't be... all will be clear in the end... <grin>

A 3.5" floppy with 1.44MB is normally formatted with FAT, i.e. you can use it with MS-Dos, i.e. a Dos formatted floppy. (You can even buy them preformatted in the store.)

The 'Unix' way is to mount the floppy (i.e. mount -t vfat /dev/fd0 /mnt/floppy) and then copy all files to it and then unmount (with 'umount'; can someone tell me where the N is?) the floppy.

This is a lot of work for something simple as copying some files. So someone wrote the mtools-package a long time ago. Now you can use the floppies as in the good old times of MS-Dos, i.e. - 'mdir a:' - 'mcopy [file] a:'

The floppies are called Dos-formatted, but almost all operating systems knows how to read/write them. It is probably the most simple way to exchange files between systems.

Offcourse there are a lot of ways to copy files between systems, but we will keep that for the next lesson <grin>.

I did it the correct way (and mounted the floppy the UNIX way - I feel more comfortable doing it like this) and this time everything went smoothly. I copied vmlinuz (2.2.14) to a floppy and copied it from the floppy to /boot on my other PC. After booting I'll still get the message that I'm running kernel 2.2.10 but that's probably because I installed an image of 2.2.14 rather then doing it 'the other way', e.g. get the source, compile, etc. On Thu, 13 Apr 2000, you wrote:

As usually I was too quick to send a message! Soon afterwards I did copy the modules and everything works quite nicely now. I haven't run 'depmod -a' yet though... Ok, now I have. Are there any additional procedures I need to take care of? At the moment I can't think of any.

Glad you got this sorted. There was no way you could have pulled that kernel off the floppy without copying the whole floppy...

You also need to copy over the modules directory. After that you'll probably want to run the command 'depmod -a' to update the dependencies file that it's looking for.
