Driver is for the Advansys Connectcom CSBFC1000 64-bit PCI to Fibre Channel Adapter. The company went out of business and sold its assets to Initio, which does not provide drivers for this product. However, the chip on the board is an LSIFC909 chip, LSI is in business and provides support...lucky. Driver was found on their support site. Designed for Windows 2000, but works under Windows XP as well.
