Try one or more of the following sizes, but the only one I've ever gotten to work is 1722 - seems to depend on specific floppy/BIOS combination: [prs@radar0 prs]$ ll /dev/fd0u1[67]* brw-rw---- 1 prs floppy 2, 124 Sep 15 09:40 /dev/fd0u1660 brw-rw---- 1 prs floppy 2, 44 Sep 15 09:40 /dev/fd0u1680 brw-rw---- 1 prs floppy 2, 60 Sep 15 09:40 /dev/fd0u1722 brw-rw---- 1 prs floppy 2, 76 Sep 15 09:40 /dev/fd0u1743 brw-rw---- 1 prs floppy 2, 96 Sep 15 09:40 /dev/fd0u1760 brw-rw---- 1 prs floppy 2, 116 Sep 15 09:40 /dev/fd0u1840 brw-rw---- 1 prs floppy 2, 100 Sep 15 09:40 /dev/fd0u1920 For example: # fdformat /dev/fd0u1722 # mkbootdisk --size 1722 --device /dev/fd0u1722 2.4.22-1.2149.nptl Alternatively, build a trimmed-down custom kernel that will fit a 1440 floppy. > In the images directory of your fedora distribution should be several files: > > bootdisk.img - floppy sized boot image > drvnet.img - floppy sized image with extra network drivers > drvblock.img - floppy sized image with extra block device drivers > boot.iso - CD sized boot image with drivers included > > They can be found, for example, at > ftp://rpmfind.net/linux/fedora/core/1/i386/os/images > > To put the boot image on a floppy: > % dd if=bootdisk.img of=/dev/fd0 bs=1024 The above would work for installation boot, but seems he might want to boot a more current kernel. Backing up a step, what is the real objective? Is a boot floppy with a kernel required, or could the objective be satisfied by having (possibly redundant) kernels on hard disk and making a GRUB boot (or LILO - won't get into religious discussions) boot floppy?
