So, it would be like this for a 16MB image.

label 8b
  kernel memdisk floppy c=16 h=64 s=32
  append initrd=bigboot/boot32mb.bin

You can use minfo to get c, h, and s.

You need to install the mtools package.

Put this in /etc/mtools.conf.

drive x: file="/test/dos.img"

dd if=/dev/zero of=/test/dos.img bs=1M count=16
mkdosfs /test/dos.img
ms-sys -f -6 /test/dos.img
