FUJITSU SIEMENS P5916

Hello. I have an old FUJITSU SIEMENS P5916 with a Core 2 Duo E6420 processor. I would like to install Core 2 Duo E7500 in it. But after the replacement, during the passage of the POST, the system constantly asks to press F1. Can I make a mod to support Core 2 Duo E7500? The original BIOS can be found on the official site of Fujitsu at https://support.ts.fujitsu.com/indexDownload.asp
And attach screenshots.
