SLI patch was probably the last secret weapon of ULi before it got acquired by NVIDIA earlier this year. It is now confirmed that the SLI patch function on the Uli 1697 will no longer work with Forceware 81.98 and later. This came as a rude shock to users as NVIDIA acquired ULI and most would expect NV to continue to support ULI and allow it to penetrate the entry level SLI market. Apparently, NVIDIA isn't too happy about the SLI patch and terminated it. Forceware 81.98 and later has a new code that will detect the SLI patch and disable two cards to run in SLI mode. Forceware 81.98 will still work in SLI with ULi 1697 boards.
