sea self-extracting disk image, possibly with a BinHex (. It will be either a Disk Copy image (819284 bytes) or a.

However, if the image you are using comes from Apple, it will not be raw. Just fdformat the floppy device for 1.44MiB as you would for any other DOS/Windows/Linux machine and write the image using a command like, dd bs=512 if=floppy_image.img of=/dev/floppy If the image you're using is a raw image (819200 bytes exactly, often used by emulators, that's easy. Unless your computer won't boot from usb or doesn't have a cd/dvd drive.Here's what I've been able to determine: A short filesystem on a floppy should work fine, as long as the blocks are in the right order.

I think /dev/fd0 is the standard name for floppy drives, but with a usb floppy drive it could be different, I suppose you could try linking /dev/fd0 to whatever name the usb floppy drive is called if it's different, but I've never tried to needed to try that.Īnd installing grub to a floppy disk should work, though a cd/dvd/usb would be big enough for a whole ubuntu live iso, and might be easier. Or if your floppy drive isn't /dev/fd0 then you could try lsblk or maybe blkid and see if it's listed, or after you plug it in check the logfiles and it should be listed in there somewhere (use dmesg or browse through /var/log/syslog and it should have some info.

Making the disk bootable / setting bootable flag isn't an ext option, I always use gparted to do that, or even gnome disks, but you can use the terminal program fdisk like fdisk /dev/fd0 and then the a command to toggle the bootable flag (may need to add 1 for the 1st partition), then w for write. This would use the whole floppy disk with no partitioning, probably the same as gparted would do, I'm not sure. If your floppy drive is /dev/fd0 then this command should make an ext2 filesystem on the floppy drive, using ext2 and automagically figuring out the other parameters (see man mke2fs for all the options). Or, you can use the terminal tools yourself, using mkfs.ext2 (alias to mke2fs). I strongly prefer gparted, gives more options and tells you more details on what it does, Disks may work, but seems more like a black-box 'click and hope' solution. For a pretty graphical way to do it, install/use gparted or even gnome-disk-utility ('Disks').
