                       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.
