They must have screwed up on the box White Lancer (doesn't really surprise me since the manual tends to be utter shash anyway!) - the minimum requirements from Bioware's website show:
- 96MB RAM for Win98/ME, 128 for XP MINIMUM (128/256 recommended)
- Minimum 1.2GB Hard Disk space, 2.0GB recommended
- 16 MB TNT2-class OpenGL 1.2 compliant video card required, NVIDIA GeForce 2/ATI Radeon recommended
So without any kind of 3D acceleration this game is a definate no unfortunately. As White Lancer has said, what is the frequency of your Celeron? The 3D card looks like the only let down (unless it's a very slow Celeron) provided you can find a compatible AGP graphics card.
