I have a very old Compaq Presario (model 6LPXE1 from the 6000T series). It has a Compaq 07E8h motherboard with an Intel P4 2.26GHz currently installed. I would like to upgrade to an Intel Pentium 4 3.0E Prescott 3.0GHz 1MB L2 Cache Socket 478 89W Single-Core Processor - OEM. How can I determine if this CPU is compatible with my motherboard? I am attaching some system specs from ASTRA32, but the demo version report is truncated. Let me know if any other information would be useful.
