I'm currently using Linux. I stopped working on the BIOS two months ago. To mod the BIOS, you need to use Windows to get a dump. Editing it requires a different application, but it's only available for Windows. Undervolting is a difficult process. If I could run the BIOS modding tools in Linux, I would install the Undervolt version. I already use the BIOS for overclocking.
Let me give you some additional information. I contacted Casper support about the BIOS version and obtained this BIOS version. I also modded it myself. I wanted to provide this information. The BIOS version you're currently using is the most up-to-date. It's not available on Casper's own website.
Sir, can I ask you something? Could you send me your serial number? I need to check something.
