[Request] HP/Compaq NX9600/zd8000/X6000 - Add Cedar Mill/65nm Pentium 4 MC

BIOS link: https://ftp.hp.com/pub/softpaq/sp31501-32000/sp31537.exe

The laptop will power on, and then shut off when a Cedar Mill CPU is installed. The latest F34 BIOS has also been installed on the computer.

The desired CPU spec is SL9KE, a Pentium 4-HT 651 on the D0 stepping with a maximum TDP of 65 watts.

Attached are screenshots from AIDA64 showing my current CPUID (Prescott-2M P4, 3.4GHz), Motherboard, and chipset (which is an Intel i915P).

I would also like to note that I have installed a custom BIOS on here which allows me to install more than 2.5GB of RAM. Obviously, that's off-topic considering I am posting in the CPU upgrade forum, but the files are on the ZD8000 RAM thread in the Phoenix Unlocking forum if anyone wants to make a patched BIOS with both Cedar mill and >2.5GB RAM support. There was also a de-whitelisted BIOS somewhere, but that's been lost.

These laptops have 2 different BIOS files depending on what graphics card your system has. One is 3082F34.M22 for ATi Radeon X300 systems, and 3082F34.M24 for X600 systems. They should be just about the same aside from different video BIOSes on hand.

If anyone owns a cedar mill CPU and an NX9600/zd8000/X6000 and are willing to test certain things out alongside me, that would be very helpful!

Thank you for taking the time to read through this. With cedar mills in these exotic laptops, we can have at least 30% less heat output, and could make these laptops run at least somewhat better.
