Yes, it has both an RSDT and an XSDT. However, acpidump found only one FADT, so it must be the same one in both RSDT and XSDT. At least, that is the understanding of the behavior of acpidump as told to me: > RSDT table will also be dumped. But all the tables obtained from >RSDT are put together with those from XSDT. >If there exist two FADT tables on the box, the two FADT tables can be >dumped. > The attached file is an example. On the box there exist two FADT >tables. One is obtained from XSDT. And another is obtained from RSDT >table. I guess my question is: is this the default behavior of acpidump, or is some flag needed?
