______________________________________ The device is Huawei CT6100, which can work normally under 32-bit 7.7, but when installing 64-bit 7.7, it reports an error: NMI port 61 20, port 70 ff NMI port 61 20, port 70 ff ———————— Perhaps this is not a valuable error message, Thank you very much for your time, regardless of whether it's worth addressing or not. I have been using OpenBSD for over 20 years, and this is the first time I encountered such a situation. Thank you very much!
