s3 specs are still available through s3 graphics (http://www.s3graphics.com) for some chipsets, although you generally have to sign an NDA. You may get a faster response calling them if you are doing this for business. The web page for the Savage development is at http://www.probo.com/timr/savage40.html and the author might be able to give you additional info. -- Kevin _______________________________________________ Xpert mailing list [EMAIL PROTECTED] http://XFree86.Org/mailman/listinfo/xpert
