Hello, the difference between architectures is the way it organize memory and do calculation. I suggest to do a compatibility layer in the kernel to do all system boots with 1 kernel. I.e. : the operation + start the kernel identify architecture define the function plus function plus begin case Intel ... intel calc of + here case Amd ... amd calc of + here case ppc ............. ... case Motorola ... so on find and replace + with plus in kernel so do all operation on memory one included THIS IDEA IS FREE AND FREELY TO USE BY ALL OPERATING SYSTEMS I DONATE TO ALL HAIKU TOO Haiku is very nice!!! What about it? Best regards Mattia Tristo
