Actually Yaifo did build an image out of the box but it did not boot on my server, with 4.8 on i386. I had to patch installboot.c in order to build an image with a valid MBR. Being able to installboot on a VND disk (not floppy) image seems to be a valid usage but is broken at least on 4.8 i386 amd64 because it won't search for MBR on a VND. The patch is attached. I guess it prevents installboot from working on VND floppy images as no MBR will be found on these. The proper hack would be to add an option to force looking for MBR even on VNDs, document it, and patch Yaifo to use this option. -- Thomas de Grivel http://b.lowh.net/billitch "I must plunge into the water of doubt again and again."
