Hello, singh, Thanks! Sorry, I checked: processor types and features There is NO "highmem support" there. The only entries there related to memory are: Non Uniform Memory Support (NUMA) and: Memory Model (Flat Memory). I am trying it with 2.6.21-rc7. With which kernel do you see "highmem support" under "processor types and features" if I may ask? Regards, Ian On 5/26/07, pradeep singh <2500.pradeep@xxxxxxxxx> wrote:

Config you kenrel to use Highmem.
