Hey everyone, I've been upgrading an old HP Compaq nx6310 laptop and ran into a frustrating issue. I installed an Intel Core 2 Duo T7400 CPU and it physically works — but only with one core. When I enable dual-core in the BIOS, the system boots to a black screen with no video output. Disabling it and running single-core works perfectly fine.

I'm already on the latest available BIOS — version F.0E (sp38742 equivalent). I found a modded F.0B BIOS floating around that removes the WiFi whitelist, but that's an older version and doesn't seem to include T7400 microcode.

Is there anyone who could inject the T7400 microcode into the F.0E BIOS for the nx6310? Or does anyone know if this has already been done somewhere? I'd really appreciate the help!
