Power-On Checks
Replace the cover of the computer and turn on the computer only. If an error occurs at
boot up, either the Serial Buffer Board is not installed properly or there is an address or
interrupt conflict. Turn off the computer, try a new address or interrupt and reinstall the
card. Be sure the Serial Buffer Board is firmly mounted in the slot.
