lnstalling an Option Card
This section explains how to install option cards in your
computer. Your computer has three 16-bit, full-length slots and
two S-bit, half-length slots to accommodate a total of five
option cards.
As you install option cards, keep these guidelines in mind:
Usually it does not matter which slot an option card
occupies as long as the card fits in the slot. For example,
you can place some S-bit cards in a 16-bit slot. When you
select the slot you want to use, make sure that no
components are touching or obstructing other cards or
cables.
If you have a DX or DX2 processor installed, you may not
be able to install a 16-bit card in the bottom slot because a
heat sink or heat sink/ fan assembly may be mounted on
the processor.
When you unpack the option card, be careful not to touch
any of the components on the circuit board or the
gold-edged connectors. If you need to set it down before
you install it, place it gently on top of its original packing
materials with the component side facing up. Keep the
packing materials in case you remove the card later.
Before you install the card, adjust any switches or jumpers
on it, if necessary. (See your option card documentation for
instructions.) Also, see if you need to change any jumper
settings on the system board. For example, if you install a
SCSI hard disk drive, you may need to change jumper 523
to disable the IDE hard disk drive controller. See page 4-6
for more information on jumpers.
