The driver can only work if the firmware allows it. Boot into BIOS (usually Del, F2, or F12 during startup) and verify:
| Setting | Recommended Value | |---------|------------------| | PS/2 Port | Enabled | | Legacy USB Support | Auto or Enabled (doesn't affect PS/2 but prevents conflicts) | | Fast Boot | Disabled (during troubleshooting) | | Secure Boot | Enabled (the driver is signed, so it's fine) | | Serial Port (COM1) | Disabled (often shares IRQ with PS/2) |
After changing BIOS settings, save and exit. Then in Windows, uninstall and reinstall the driver as shown in Part 7.
