Restoree is a tool that can restore the original contents of the EEPROM when Xonar cards are no longer recognized. I’ve extended the original restoree.exe with support for the following cards:
- Xonar STX II: PCI\VEN_13F6&DEV_8788&SUBSYS_85F41043
- Xonar DG SI: PCI\VEN_13F6&DEV_8788&SUBSYS_855E1043
Follow this guide on how to create a USB bootable disk and use restoree.exe to restore the original hardware ID of your card but use restoree.exe from this page if you need it for Xonar STX II or Xonar DG SI cards.
