LinuxDan, Whats the exact model on that board? And chipset? Tryong to look for it on Intel's site. Thanks Randall Jimen I am using the Intel 2.53 CPU and MLB that uses hyperthreading on triple boot system running RH8, W2K and XP. Actually RH8 utilizes it better than MS. I have 200% increase in speed and data transfer rates. Dan
