Switches away from card are off.. RTFM Or the Switch.. It says right on the switch.. Try these settings. SW: 1=Off (Depends on termination) (Off = Software) 2=On (IO Port 0x134) (Rarely used) 3=Off (IO Port) 4=On (IO Port) 5=On (Floppy disabled) 6=Off (Bios address) (DC000H) (Make sure nothing 7=Off (Bios address) else is using this address) 8=Off (Bios address) You only have one device so the 1542CF needs software termination for it's end of the chain. That is SW1=Off. SW2,3,4 = 0x134, Just a low address thats not used to often by others! SW6,7,8 = Bios address.. This you'll need to know if anything else is using. Alot of items use D8000h as thier default! As you see I've suggested dC000h. -Enjoy Gary ~~~~~~~~~~~~~~~~ Improve America's Knowledge... Share yours The Borg... Where minds meet (207) 929-3848
