and the tab slides into the recessed clip attached to the drive mounting bracket.
3. Align the holes in the shield's 90-degree lip with the thumbscrew holes on the back of
the chassis.
4. Replace the thumbscrews removed previously to attach the shield to the chassis.

Adding Expansion Cards

You can add Peripheral Component Interconnect (PCI), Plug-n-Play (PnP), and Industry
Standard Architecture (ISA) expansion cards by installing them in the system's expansion
slots. The following illustrations show the location of the expansion slots on the system
board. Install PnP cards in any expansion slot. The lowest PCI slot and the highest ISA slot
are shared; you can install an expansion card into one or the other, but not both.
NOTE: Plug and Play (PnP) support is not currently available in Windows NT.
