X-BeenThere: freebsd-questions@freebsd.org X-Mailman-Version: 2.1.5 Precedence: list List-Id: User questions List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Wed, 10 Feb 2010 21:56:15 -0000 I just realized that cdboot does not contain the kernel as boot.flp used to, so I guess /boot/kernel has to be there... So it does not seem to work with mkisofs. I did mkisofs -J -R -no-emul-boot -b ./cdboot -iso-level 3 -V FreeBSD_Custom -o custom_FreeBSD_8_0_i386_cd.iso custom_FreeBSD_8_0_i386_cd and it throws: mkisofs: Uh oh, I cant find the boot image './cdboot' I tried with the absolute path for cdboot and it does not help either. From the mkisofs man page it says that -no-emul-boot has to be added if the size of the image file is not 1200, 1440, or 2880 kB. I noticed that the cdboot file is only 1.2 kB, so I guess -no-emul-boot is required... Do you have an idea what could be wrong? Thanks! Pierre-Luc Drouin wrote: > Great Thanks!
