Install the firmware

  1. Switch the PS/2 off and take the card out of it.
  2. Choose the build that matches your SW_CFG2 switch: 16-bit (on) or 8-bit (off).
  3. Connect the USB-C port of the card to your computer.
  4. Hold the BOOT RP button and press RESET. Release both. A USB drive appears on your computer.

Warning. Never plug the card into the PS/2 while the USB-C cable is connected.
