Hi, I tried this option "linux acpi=off pci=nommconf" as well but the problem is when I use this I can install the OS but when try to boot on to the OS it's hang up on the boot up progress bar screen of the CentOS and I can't do any thing. So I checked it with the text mode loader it was the same problem can any one help me to over come this.
By "the text mode loader" do you mean booting to runlevel 3?
You will probably find that anaconda put "acpi=off pci=nommconf" on the grub kernel line. Try interrupting the boot and typing "a" when grub starts and editing the line to delete those and "rhgb quiet" and adding "3" for runlevel 3. If the boot still fails, reply to the list with the last output you see before it hangs.
