I have a linux box with mandrake installed, its an old box so i am still with the older version to ensure stability as i am afraid that the new version might not work this old age box. I have to keep the kernel argument acpi=off while grup loads the GUI version else the system crashes and i cannot boot into the system. The problem is i have to do it manually everytime i boot the computer, and once the machine has booted, it automatically edits the grub settings and the acpi=off vanishes. How to change kernel arguments in grub manually to keep the changes saved? Please help, m a noob...

If you have any text editor this is too easy... Open terminal and change the file permissions for grub boot loader so that you can save changes to it :

chmod +rwx /boot/grub/menu.lst

menu.lst is the file which is responsible for saving the boot location, boot order and boot options including kernel arguments. Now open the menu.lst file from a text editor application and add acpi=off under appropriate section, and now save the file. Now again change the file permission so that it doesn't change automatically or by mistake :

chmod -rwx /boot/grub/menu.lst

Thats it, you're done...
