I asked this question over on SO. I have tried
dd if=kernel.sys of=/dev/fd0 bs=512 seek=1
to get this file to write to the floppy. It is a kernel shell that must be written to the sector immediately following the bootsector of a disk to boot the PC. No matter what I've tried, for some reason,
kernel.sys is not writing to the floppy. I know the bootstrap loader is being written and executed. However, it cannot find the kernel to load the shell.
Any ideas on what I am doing wrong? I mean, really, how is it so difficult to get this file written to a floppy?
