The newer /sys/i386/boot/biosboot/Makefile contains this comment: # Assume hd(*,a) instead of wd(*,a) if the boot seems to happen from # a hard disk. # This can be useful for people booting in a mixed IDE/SCSI environment. #CFLAGS+= -DBOOT_HD You gotta ``make clean obj all install'' there after munging the CFLAGS, and you have to re-label your disks to install the new bootstrap.
