Subject: How to prepare an ISO 9660 CD for booting via GRUB ? X-BeenThere: grub-devel@gnu.org X-Mailman-Version: 2.1.5 Precedence: list Reply-To: The development of GNU GRUB List-Id: The development of GNU GRUB List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Thu, 01 Apr 2010 13:50:33 -0000 Hi, i would like to learn how GNU xorriso can make use of GRUB. Are there any specs available, or an example of a GRUB enhanced ISO 9660 image that boots from CD on PC BIOSes ? I know about ECMA-119 (ISO 9660) and El Torito CD booting specs, but few about GRUB. In january 2010 Robert Millan announced GNU isofsmk. In the course of the following discussions he wrote: > So if you'd like to create a GRUB bootable disk, you'd do something > like: > cat boot.img core.img > tmp > mkisofs --embedded-boot tmp -o grub.iso -r somedir I did this with isofsmk-1.13 and a dummy file "tmp" (not boot.img+core.img) in the hope to learn what kind of El Torito record gets produced. But i cannot spot any. mkisofs just copied "tmp" to the System Area in block 0 to 15 of the ISO image. So i would need a more realistic test setup or some explanations. Any help with a quick start is appreciated. Have a nice day :) Thomas
