Isn't the VESA local bus standard limited to 40MHz for plug-in cards? (but hard-wired local-bus stuff on the motherboard can go up to 66MHz?) Wouln't this be a problem in a true 50MHz machine? In this case a DX280 (if one were ever produced) would be the highest speed you could have without causing problems. ------------------------- Kevin Fluet fluet@ee.ualberta.ca -------------------------
