INSTRUCTIONS TO REMOVE A USER'S CONFIGURATION AND RESTORE THE WINDOWS NT DEFAULT CONFIGURATION These instructions occur with systems such as the Dell Optiplex, and some other systems with integrated devices on the motherboard. The problem here may have been that your system has installed our board after the bridge. The PCI bridge enables multiple PCI buses. If the PCI slot is on a PCI bus greater than 0 then it will not allow an address change to the legacy address of 278. The port will show up in the Lavaport applet in Control Panel with an exclamation mark (!) to say that the port is not enumerated. The bus number that our card is on is listed in the event viewer under the detectlava message. Unfortunately, if this is the case on your system then you cannot change the address of the Lava Parallel PCI. To set the Lava Parallel PCI back to default: 1) Boot into NT4.0 without the card installed 2) Go to Start|Run and type: regedit and click ok. 3) Go to: HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\DetectLava\UserSetings 4) Remove the subkey (folder) in here by deleting it (but NOT the UserSettings KEY!!). 5) Shut down and place the card back into the PCI slot. 6) Boot back into Windows NT.
