opensuse and cpu scaling help needed

[BlancHall]

Hiya,

New to hp 2133 and linux really.

have installed opensuse 11.1 all is well at the moment except for cpu scaling.

could someone post exactly the steps i have to take to edit the /boot/grub/menu.lst file and where abouts i insert the acpi_osi=”!Windows 2006” line in this file.

Everything works except cpu scaling

thanks in advance

Heya,
Nice to see you did some research

With openSUSE you can edit the menu.lst file through YaST2 (I just remembered that :P)
SDB:The Boot Manager Grub - openSUSE

You will need to find the "Expert manual configuration" section which will present you with your current menu.lst file.

To add the acpi_osi parameter, find the top-most line starting with "kernel" and add the parameter at the end on that line. Following the example menu file listed on the openSUSE wiki, it should look something similar to the lines below, once you're done:

title linux
kernel (hd0,4)/vmlinuz root=/dev/hda7 vga=791 acpi_osi="!Windows 2006"
initrd (hd0,4)/initrd
title windows
root (hd0,0)
makeactive
chainloader +1

Remember: this is only an example, do not modify the (hdx,y) nor root=/dev/hdxy values! The important thing is where you enter the acpi_osi parameter.

Note that this step might have to be repeated when you upgrade the kernel for e.g. security updates. I'm not on my openSUSE machine right now so I can't check the menu.lst file myself, though if a line near the top of the menu.lst file starts with:
# kopt (blablabla...)

it's even better to place the parameter at the end of this line, since the parameter will survive kernel upgrades.

When you are done modifying the file, remember to save the file and then press "Finish" so that GRUB is updated with your modifications.

Post back if you need more assistance!
