I saw some people were looking for this driver as well, this came off the same cd I got the 931 drivers from, only this is for the 933. Like the 931 drivers, these are the BASIC driver set found in the 933 directory on the CD, just unzip onto a floppy or in a directory. As I mentioned before I think a company called BTC actually makes the card and OPTi just makes the chip. check out www.btc.com.tw thats the URL printed on the CD. These drivers and/or the 931 drivers will probably work for the BTC 1817DSL card as well since thats the actual model number printed on the box that the card and CD came in.
