Step 6.

Carefully insert the edge connector J1 (see Figure 2.1) of the
host adapter into the PCI slot. Make sure the edge connector
is properly engaged before pressing the board into place as
shown in Figure 2.2.

Step 7.

To plan on hooking up another host adapter on the same bus
as this host adapter, or an 8-bit device on 68-pin connector, see
the Channel Switches section discussed later in this chapter.

Notice that the components on a PCI host adapter face the opposite way
from those on other non-PCI adapter boards you have in your system.
This is correct, and the board is keyed to go in only one way.
