Step 9 Install Adapter Cards,
Continued
EISA adapter cards have longer and denser
fingers on the edge connecters than ISA
adapter cards. The EISA slots on the
motherboard have two rows of contacts, one
below the other.
The ISA slot can be inserted into the EISA
connector only far enough to make contact
with the upper row of contacts. EISA
adapters have longer fingers to allow
contact with the second row of contacts.
See the following graphic.
When installing EISA adapter cards, make
sure that they snap in twice and are fully
seated into the EISA slot. If the card
makes contact only with the upper row of
contacts, it does not function properly.
