Hi, > > One last thing please? After install should I have to provide this as > a boot parameter? If so how do i do this? You might have to. Simplest way is to login, open a terminal window, su and edit /boot/grub/grub.conf You will see a boot line (looks something like Kernel-2.6.16.2069_FC4 rhgb quiet). Add the line noacpi (or whatever command you used to get the software to install), save and boot. Any updates to the kernel will automatically inherit this command.
