HP 98726A Interface Card
4. Install the Interface Card in Your Computer or Expander.
a. Insert the card, component side up, into an empty I/O slot in your
computer. Tighten the thumb screws on the metal end plate until the
end plate is flush with the back of the computer.
b. If you have other interface or accessory cards to install, leave the cover
plates off; otherwise replace them.
5. Record the Select Code
If you changed the select code from the default
setting, record it on the "Select Code Record" form on the Chapter 5,
"Interface Cards" tab. If you did not change the switches from their original
settings, you need not worry about a select code, since the internal code for
the system console is used.
