MB is GA-G31M-S2L. the MB is old model and very slow in polling usb even if I set *acpi=3D1 in plan9.ini. my nvram setting is nvram=3D/dev/sdU6.0/nvram and we must find the value 6.0 by experiment: first, without nobootprompt and then nobootprompt=3Dtcp I have not good result for bell-labs version. thanks all.
