Step 6. Carefully insert edge connector J1 (see
adapter into the PCI slot. Make sure the edge connector is
properly aligned 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
Section 2.2.10.1, "Channel Switches,"
chapter.
Notice that the components on a PCI host adapter face the
opposite way from non-PCI adapter boards you have in your
system. This is correct, and the board is keyed to go in only
one way.
