# kopt=UUID=[followed by a long string of random characters]<br><br>At the end of the # kopt line add your vmalloc=256M setting. So for my<br>system the completed line would be:<br><br># kopt=root=UUID=2ef2c79b-0495-4a52-9d59-a83e5a870371 ro vmalloc=256M<br>
<br>This will preserve the change for any later kernels that get installed.<br>You will also want to add the option to the current default kernel. Look<br>further down in the file for a section that looks like this:<br><br>

<p><br>Thank you James!!! I edited /boot/grub/menu.lst with vmalloc=256M in both the places you suggested. Both tuners are working now.</p>
<p>Thanks again,<br>Greg</p>
