KT880 WITH Athlon XP-M 2500+
WITH Central Brain Identifier, default HALT STATE disabled,可ENABLE, STPGNT STATE disabled, 可ENABLE, enabled both, working, no 爆音
I went though 3 CPU and 4 MB, each is different, so look like CPU and MB design, each played a role.
用 Central Brain Identifier 檢試看看 is the right way.
