Basically, while your ``start 204800'' is the valid number, : you have to convert this into the C/H/S idea your NCR BIOS has for : this sector number. 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). Lars.
