Hello, The Gujin bootloader can simulate an El-Torito boot process (creating a virtual BIOS disk with 2kbytes sectors) from an iso file image in a E2/3/4FS or FAT filesystem (instead of a real CDROM). The part simulating this El-Torito drive stay in low memory and leave a signature (an extension of "$INT13SF") which describe the exact location of the source file (i.e. partition and fully qualified filename, and PCI description of the disk from BIOS INT013/48). I have written an UNTESTED patch (attached - sorry still not mastering git) in dash to display the filename of this "source iso" (and mount in /isofrom if needed). I am happy to release this patch under any GPL version, even BSD without advertisement close if needed. Gujin is available under GPL at sourceforge and http://gujin.org , to test install on a usb stick like: sudo ./gujin /media/USBSTICK/gujin.ebios and boot a PC (virtual PC have bad BIOSes, better a real physical one) which has a live image in the /boot partition (ext2/3/4 formated), and select to boot the "noemul" option in the Gujin menu. NOTE that I am releasing too early, I have tested that this script display the right filename in different configuration, but I still need to master the generation of a live CD! What are you thinking of this approach? Regards, Etienne.
