I forgot to mention this! I did run into the same issue, but you do not need the .bat file to create a backup. Instead, you can create a backup of your BIOS by opening an admin-level command prompt window in the folder containing fptw64.exe and running the following command: fptw64.exe -d BackupBios.bin -bios

Four years since this thread was started, it's still perfectly useful. Thank you very much, @svl7. I've finally been able to install my Intel Dual Band Wireless-AC 7260 into my old Y500. I ran into an issue creating a bootable DOS drive (the HP tool kept failing without any additional info; I was using a 16 GB USB 2.0 drive and Windows 10), but I did a quick Google search and found a tool called Rufus recommended by HowToGeek. I used Rufus to load the drive with FreeDOS, then transferred prr2.exe, fpt.exe, fparts.txt, and the modified BIOS image onto the root of my drive. I had no errors using any of the provided files other than the HP tool. Thanks again for keeping those links updated and working.
