Making a grub boot floppy
Having spent ages trying different methods of making a boot floppy and not having much success
I finally found a method and just wish to pass it on.
fdformat /dev/fd0 (or the number of your floppy drive)
Assuming that you have a correctly configured grub on your system we can now write it to the floppy by now doing;
Check that the floppy works by rebooting from it. If the boot floppy works then it is job done.
Creating a boot cd from the boot floppy
If you are thinking, why make a boot cd when you already have a floppy then the reason
is that floppies don't tend to be very reliable media in my experience and just when you really
need it, it doesn't work. A cd on the other hand, if stored properly is very reliable. So here's
how to make a boot cd from the floppy
Now we need to create an image of the floppy in this directory, so do;
dd if=/dev/fd0 of=/home/your_user_name/tmp/boot.img bs=10k count=144
Now we have an image of the floppy disk we can create a boot iso to burn to a cd. If you want to know the technical background then here is a reference. Here are the mechanics. Again from a consol do;
mkisofs -r -b /home/your_user_name/tmp/boot.img -c boot.cat -o /home/your_user_name/tmp/bootcd.iso .
Note the "." on the end of this line it is important
