This is assuming that you have another FreeBSD box which works properly, and that you can copy the ld-elf.so.1 file from. The intention is that you use a different floppy than the ones you use to boot from, and swap them in and out as required. > > # echo ./ld-elf.so.1 | cpio -o > /dev/fd0 > > When you say "write the file direct" do you mean that my system's "/" root > directory may also be directly written to, without having to first mount it??! Not like this: writing direct to a block device like this will destroy any filesystem already on the device. That's generally not what you want, but it can be permissible in extremis to trash some floppy disks... > > Then to extract the file: > > # cd /usr/libexec > > # cpio -i < /dev/fd0 > My apologies. This all seems a little scary, and does not sound proper... Absolutely. It is both scary and improper.
