Dell OptiPlex E1 - Manual (Page 59)

The system accommodates up to three expansion cards, which can be a mix of 32-bit PCI expansion cards and 8- and 16-bit ISA
expansion cards. (See Figure 6-2 for examples of ISA and PCI expansion cards.)
Figure 6-2. Expansion Cards
Expansion Slots
Four expansion-card connectors reside on the riser board (see Figure 6-3). Because two of the expansion-card connectors share
an expansion-slot space, a maximum of three expansion cards can be installed.
Expansion-card connectors ISA1 and ISA2 (at the top of the card) support 8- or 16-bit ISA expansion cards.
Expansion-card connectors PCI1 and PCI2 support 32-bit PCI expansion cards.
NOTES: Connector PCI2 shares expansion-slot space with connector ISA1, so only one card of either type can
be installed in the shared slot.
Because of the height of the hard-disk drive, expansion-card connector PCI1 is limited to an 8.75-inch-long card.

Installing an Expansion Card
To install an expansion card, follow these steps:
1. If you are installing a non-Plug and Play ISA expansion card, enter the ISA Configuration Utility (ICU) and add the
new expansion card to your configuration.
