I tried to install the 3.9 on an old IBM 300GL with a Celeron 466/192 RAM, I do the beginner install, when I input the user password I got an error that the white background image can not be loaded, and the password field is corrupted I can't see what's in there, after many retries I still can not verify my password. The onboard video is intel810 with 1M shared memory that I can't change, but I installed Ubuntu on the same hardware without problem, it seems that Knoppix has much higher requirement on hardware.
