Hi, Just Boot from Xandros CD it gives first instruction to you "press SHIFT for Troubleshooting".
press SHIFT key, it gives too many options, you can select "256 Color Setup" in the given option and Press ENTER and install Xandros step by step as usual installation.
After installation completed, you can change the 256 color resolution to 16 bit or us your wish.
Thats all.
I meet the same problem with my AGP card. Now no problem with XandrOS completely installed with Windows XP SP2.
Try it. :roll: :roll: :roll:
