Thanks for the info.My IGD get BSOD when run 3D program in legacy mode, and get
BSOD during boot in UPT mode. So I guess Win7 can handle it too. (Ah, I've
tried UPT before, stopped by the BSOD, so have the impression that UPT won't
work)Will try with another CPU later.

Windows 10 can handle it. Didn't try Windows 7 though.
