Not really, Tom, it depends on the individual situation. I've never had a problem with bios shadowing under linux and I've been doing it for 12 years professionally in linux systems, both with my systems and with customer's systems. System boards that I have had experience with involving this include Tyan, Asus, Abit, Shuttle, FIC, Young Micro(no longer in business), MSI, and a bunch of others I can't remember right now. Most of the bioses I've encountered have been Award bioses. I try to shy away from Phoenix. As I was saying, Matrox is a special case because it had a wierd bios that didn't like shadowing. This was a problem not just under Dos but apparently also under Winblows and Linux too. I remember this situation because at one time I was into 2d accelleration back in my Dos gaming days, and I ran PC Bench alot. Version 9. The Matrox would crash the Dos machine when shadowing was enabled. Shadowing is always desirable over non-shadowing because accessing the bios directly is extremely sloooowwwww. The Matrox card was different because it just wouldn't work any other way other than shutting down shadowing. ATI was the only other manufacturer that ever produced a card that acted like that, and that was in the 1990's. LX
