Many of the cards in the i810 family have only a very limited amount of video memory on the card. So if you want to get anything over 800x600 on them, you need agpgart. On some of them the i810 driver won't start even in 800x600 mode, so VESA is the only option. -SB _______________________________________________ Devel mailing list [EMAIL PROTECTED] http://XFree86.Org/mailman/listinfo/devel
