It works fine on OpenSolaris/amd64 host. It also works on OpenBSD/Sparc64 host, which is big endian. Linux/i386 works too, so 32 bit case is covered. I doubt that this can be a problem in OpenBIOS, I find QEMU more likely suspect. Can you boot any other big endian targets on PPC, for example PPC? ^ permalink raw reply [flat|nested] 5+ messages in thread
