I dumped the very first of .../lun0/part1, there is an ELF header and a lot of binary following. and the machine doesn't boot. Because of that error I think. part1 is 8.2 MB and vmlinux about 4. parted shows the part as prep boot. > > > What I made first last evening was (after chroot on /target ) > > dd if=vmlinux of=/dev/sda1 > > with apparently no error (except that the machine is not booting).

I tried also boot net then load : ....console=tty0 noinitrd, hoping it was able to find root as /dev/sda3 which exists now but always the same: cannot open root device "<NULL>...." if load: ... root=/dev/sda3 we have cannot open root device "sda3..." just for fun load= ... root=/dev/scsi/.../part3 all the same Friendly, Felipe
