Might be that you need to disklabel the image of the filesystem on which you copy this files, ( not talking about the mfs filesystem that is crunced into the kernel ) So, try the following. Mount this image by doing 'vnconfig /dev/vn0 /pathtobootimage/myimage.img' where myimgae.img is the 2.88 M boot image. Now do a 'mount /dev/vn0 /mnt' now do a 'disklabel -B -b /mnt/boot/boot1 -s /mnt/boot/boot2 /dev/vn0 Something like above, try and see if it works. If it doesn't create a new filesystem, do newfs and disklabel, then copy all those files of yours onto the filesystem. You actually don't need all those files. Anyways, i think it's the bootloader itself thats not loading the kernel on the CD ( inside the 2.88 M) image. And to correct that you need to reinstall the bootloader, and the bootblocks. That is boot0 to boot2 On 17-Aug-00 Patrick Bihan-Faou wrote: > Hi, > > > I am trying to build a bootable CD... Now this sounds like something trivial > enough to do when you know what you are doing.
