[REQUEST] Dell PowerEdge SC430 A04 support for Q9500 and memory remapping for chipset

[Dantare]

Hello,
I have a Dell PowerEdge SC430 bios version A04 (Phoenix) with a Pentium D 925 and 4GB RAM running on the iGPU and Debian 12 installed. I would love to upgrade it with a Core 2 Quad Q9500 and an Radeon RX460, but I can't because of the BIOS. The RX460 works fine with only 2GB RAM inserted, but it hangs with 4 GB, so I think the issue is with memory remapping/memory hole on the Intel 3000 chipset, which apparently supports it in hardware but Dell doesn't offer this option in the settings. About the Q9500, the socket and TDP are not a problem, it doesn't currently work because the bios doesn't understand the microcode blob (0x10677) and probably has a whitelist of validated CPUs. 

So I would like to request the following modifications to the BIOS:
[*]* Memory remapping enabled for Intel 3000 chipset
[*]* Q9500 microcode (CPUID 0x10677) added and CPU whitelist patched
[*]

Tell me if I have to provide something additionally because I'm not really knowledgeble in BIOSes. 
Thank you!
