Mostly, indeed. There are a couple of differences, though, the most important being that the address sequence as 555, 2AA, 555 instead of AAA, 555, AAA. Then there are a couple of other differences as well, such as when reading the product code, and the fact that the block layout is uniform. There may have been some other things as well, but I don't quite remember. Fredrik Tolf -- linuxbios mailing list [email protected] http://www.openbios.org/mailman/listinfo/linuxbios
