I think i've found why new BDA drivers after 1.2.2.9 release hang my system! Indeed when i formatted the system, the first BDA driver installed was 1.2.2.9 release. I think the main problem is that i would uninstall completly old drivers. Perhaps with new drivers, the system hangs because of some registry keys that weren't removed properly.
Can someone tell me how to unistall completly Twinhan BDA drivers?

delete them in the device manager

delete them

delete them out of windows\system32\drivers

delete them out of windows\driver cache

delete .inf files in windows\inf that contain the text "twinhan"

Tried this procedure........same issue as before; XP hangs during BDA 1.2.3.8 installation!

Yup I can't install anything later than 1.2.2.0 on my Win2000 systems and there is no explanation or useful feedback from TwinHan as to what the problem is

So, you have the same issue? On your Win2000 system it freezes when you try to install BD later than 1.2.2.0? For me i can install till BDA 1.2.2.9; all later versions hang up my system!

Did anyone find a fix for this?
