                           RESERVED MOTHERBOARD I/O ADDRESSES

    PROBLEM:     Users cannot configure add-in cards which use I/O addresses
                 398 through 39F hex in Bravo MS systems.

    CAUSE:       Due to a problem with the SIS chip set used on the Bravo MS
                 motherboard (202762-XXX), the above I/O addresses are reserved
                 strictly for system use.

    SOLUTION:    Configure the add-in cards to use addresses other than 398
                 through 39F hex.
