hello Thanks for all the information on this page, most usefull, Running kernel 2.6.28 - 10 I have over clocked to 850 (using the 3 lines in x term) all works just fine and have added QB and the stock button to go back to 600 just in case I would like to add a ideal button as well but not at 1000 but at 850 If i understand rightly I can do : 1. Launch xterminal 2. Sudo gainroot 3. kernel-config load lv 4. kernel-config limits 250 850 5. kernel-config save ideal_850 Then in snippet _ideal_1000 I just rename load ideal_1000 to load ideal_850 (ligne 27) Is this all Ok before I try it ? I may of missed something completely here as a noob to Linux, so please bare with me many thanks
