Hi List, I've asked the very same question here before, but got no answer. Probably, the experts, who might have known the answer just overlooked it... (sorry guys for addressing some of you directly, but I'm really in trouble). The thing is that I desperately need to get the O2 to boot from its HDD, it's all installed and supposed to be used as a standalone box. I'm using kernel 2.6.6 with minimal patches from Ilya and as to be expected it does not boot from the volume header. Arcboot seems to be the way to go, but I'm not able to compile the bootable arcboot.IP32 image. When I've tried to self-compile it with gcc 3.3.3 the image size was over 500K and it did not do anything at all. Self-compilation with gcc 3.4 fails during linking. In a mean time I've extracted the binary arcboot.IP32 image from the debian package and this one at least does something: it loads the kernel into memory (goes very slow), recognises a 64-bit executable and even starts it... But immediately after the kernel crashes. Any idea why it could be happening? In some other thread, Ilya have mentioned, that he has a "highly hacked" version of arcboot. Is it available anywhere? Or are other other solutions? Thanks in advance, Max
