The 1542 cards will push the ISA bus beyond its limits depending on its configuration, and not all motherboards can handle this. Try running the DMA test. Also try reducing the speed down, and run iozone again. Probably work fine. When using the 1542, I always look for motherboards that I can change the increase the ISA clock, and then bump up the DMA speed. Screws up most sound cards, but the performance increase is nice. > -- > Stan Brown stanb@netcom.com 770-996-6955 > Factory Automation Systems > Atlanta Ga. Tom
