Well the VGA on motherboard isn't disabled when you install a 8514/A-adapter in the special "video" expansion slot. The VGA signal goes through a connector in the slot to the 8514/A. That way the 8514/A doesn't have to provide VGA emulation, it can use the VGA signals from the original adapter instead. I don't know if it's possible to install the card in another slot. There are other cards in addition to those you mentio- ned. Don't remeber the manufacturers (maybe Genoa and Paradi- se?), but the new PC Magazine listed them in the 'Advisor' column. BTW, IBM announced a new video adapter, XGA (extended grap- hics array), that is used on the motherboards of the new PS/2s. Supposed to be X times faster than normal VGA, 8514/A compatible and add some new graphics modes (640*480*65536 co- lors). It's not yet available as a standalone adapter but so- meday ;-). -- _________ Teemu Mottonen | | internet: tmottonen@cc.helsinki.Fi University of Helsinki | | bitnet: TMOTTONEN@FINUH Dept.of Computer Science |_________| decnet: HYLK::TMOTTONEN
