Thanks This confirm previous link is wrong and need fixing "ipxe loads debian/linux recognises it as efi stores it in memory with the command line, then loads debian/initrd.gz names it one.gz and stores it in memory, loads debian/preseed.cfg names it pressed.cfg and puts it in a cpio archive called two" _______________________________________________ ipxe-devel mailing list ipxe-devel@lists.ipxe.org https://lists.ipxe.org/mailman/listinfo/ipxe-devel
