I have an 850mhz Athlon with AMD Irongate chipset running win 98SE. I installed the ADS firewire card and the system recognises it with no problems, device manager says everything is working properly. When I set my Sony TRV820 camcorder, I get a message on the screen that windows needs a file called 61883.sys. This file is not located anywhere on the windows cd or in any of the cab files. Searching Microsoft web site brings up two articals on the 61883 standard but no sys file of that name. Can anyone help me out?
