Feizhou ... thank you for the reply. Feizhou wrote: "When you get the grub screen, hit esc to stop the count down. Edit the kernel line and add 'acpi=off' to the list of kernel parameters. Then boot (run) that grub entry. After you have got in, edit all your kernel parameters to add acpi=off. That is how I get Centos 64-bit to run stably on my Asus manufactured board. Asus BIOSes are crap and their acpi table setup is lousy." I only have one question ... if it does successfully boot using the "acpi=off" parameter how do I actually edit all of the kernel parameters to reflect the change? What file do I edit ... need some hand holding here if you don't mind. Thanks again Ed -------------- next part -------------- An HTML attachment was scrubbed...
