Howdy Robert, The original posting was to solve an EFI boot CD need. Otavio is obviously a supporter of GRUB and wondered if there was a solution based on it. I don't think there is at the moment.
My thought for an i386 Legacy/EFI Install CD is that it would use the Hard Drive emulation mode instead of the No Emulation mode. This means the El Torito section needs to point to a Partition Table which has only one (32MB) partition which contains a Boot Sector which loads this original BootImage as a file now in a FAT File System instead of a raw image contained in the El Torito area. The file can be hidden. The rest of the files in the FAT File System area of the El Torito Hard Drive Emulation area would be the i386/AMD64 EFI files StartUp.nsh, elilo.efi (or eGrub.efi), elilo.conf (or eGrub.conf), initrd, and vmlinux. There are some components of this fix which are related to the packaging process to the build, some related to fixes in files, and some related to the install process. I am going to repost something a little more descriptive perhaps starting with debian-cd and when I identify the packages that need to be fixed, move back to debian-install and/or debian-boot.

Work has been done as part of GSoC to: - make GRUB able to boot from CD via eltorito - make GRUB cable to chainload to eltorito CDs I plan to get that synced with CVS and merged upstream. I haven't got time to do it yet, though. Other nice features that may be interesting for CD images are 64-bit cpu detection, and scripting support. As for EFI (is this thread about EFI?), it's supported, but still not very well (check the BTS). Anyway, most of non-ia64 EFI machines are Apple boxen which provide a way out of the EFI madness (so-called boot camp). -- Robert Millan <GPLv2> I know my rights; I want my phone call! <DRM> What use is a phone call, if you are unable to speak?
