Please have a look, and pass me any comments. I also have the same patch for 2.4, if you are interested it's available on my Linux page on http://www.infowares.com/linux // Thomas diff -r -u linux-2.5.69.orig/arch/i386/Kconfig linux-2.5.69/arch/i386/Kconfig --- linux-2.5.69.orig/arch/i386/Kconfig 2003-05-05 00:53:02.000000000 +0100 +++ linux-2.5.69/arch/i386/Kconfig 2003-05-07 18:00:11.000000000 +0100 @@ -273,6 +273,48 @@ endchoice +# +# Select the exact K7 model for optimization purposes +# +choice + prompt "K7 Model Selection" + depends on MK7 + default K7_STD + +config K7_STD + bool "Standard Athlon/Duron/Other" + help + Select this if you have a standard Athlon or Duron processor, or + another varian that is not listed below.
