The CIO-DO24DD BASE switch can be set for address in the range of 000-3FC so it
should not be hard to find a free address area for CIO-DO24DD. Once again, if you
are not using IBM prototyping cards or s ome other board which occupies these
addresses, then 300-31F HEX are free to use.
Addresses not specifically listed, such as 390-39F, are not reserved and may be
available. Check your computer for other boards which may use I/O addresses.
3.2 INSTALLING IN THE COMPUTER
1. Turn the power off.
2. Remove the cover of your computer. Please be careful not to dislodge any of the
cables installed on the boards in your computer as you slide the cover off.
3. Locate an empty expansion slot in your computer.
4. Push the board firmly down into the exp ansion bus connector. If it is not seated
fully it may fail to work and could short circuit the PC bus power onto a PC bus
signal. This could damage the m otherboard in your PC as well as the
CIO-DO24DD.
