Which ASUS model of board, there are no less than 3 ASUS PCI 486 MB and the memory bandwidth on all 3 of them are different. Wich AMI model motherboard, I don't know how many EISA boards they make. I suspect you may be comparing CPU <-> memory bandwidth when you look at the system load more than anything. -- Rod Grimes rgrimes@gndrsh.aac.dev.com Accurate Automation Company Custom computers for FreeBSD
