Dolphins PCI Express adapter cards typically includes a non volatile storage for PCIe configuration data.

This chapter documents the proper way to upgrade a Dolphin PCI Express MXH930, MXH932, MXH94x, and MXH95x adapter cards.

The Dolphin eXpressWare driver package for your installed card must be installed and running in order to upgrade the firmware.

To upgrade the adapter PCIe configuration data under Windows - Just execute the upgrade_eeprom.ps1 script from an elevated powershell:

PS C:\ > Set-ExecutionPolicy AllSigned -Scope Process
PS C:\ > & "${env:ProgramFiles}\Dolphin Express MX\Util\upgrade_eeprom.ps1" --upgrade
      

After the upgrade has completed, it is required to fully power cycle the system to apply the changes (including removal of VAux). The new firmware is loaded when the machine powers up.
