I have set manually the boot-drive to sd(0,a) and wrote the new 
disklabel/bootsector on a floppydisk

/sys/i386/boot/biosboot/boot.c:
  part = 0;
  unit = 0;
  maj  = 0;
(comment out various #ifdef's, which can alter one of the three variables
 in this area of the source)

type make and wrote sdboot and bootsd with the disklabel-command on a 
floppy.

This special floppy boots from sd(0,a).
