ISA Configuration Utility
The OptiPlex E1 systems contain an advanced expansion subsystem that can support a mixture of traditional ISA expansion cards (called legacy cards), Plug and Play
ISA expansion cards, and PCI expansion cards. The ISA Configuration Utility (ICU) included with the computer provides a means of avoiding resource conflicts that
might arise from such an arrangement.
After all legacy cards have been configured with the ICU, the computer automatically assigns any required memory space, IRQ lines, and DMA channels to any
installed Plug and Play ISA expansion cards and PCI expansion cards the next time the computer is rebooted. "Configuring Expansion Cards" in the online
System
User's Guide describes the ICU and provides instructions for using it to configure the computer.
Low-Profile Chassis Riser Board
ISA1 and PCI2 share the same card-slot opening. The OptiPlex E1 computer has a passive riser board, with no PCI-to-PCI bridge. The riser board includes the P1
connector (for connecting the NIC to the riser board cable) and an LED. If the LED is on, the riser board is receiving power; if off, the riser board is not receiving
power.
Mini Tower Chassis Riser Board
The mini tower computer has four expansion-card slots. The riser board has two ISA expansion-card connectors and two PCI expansion-card connectors.
The riser board is active, incorporating PCI-to-PCI bridging. The riser board includes the P1 connector (for connecting the NIC to the riser board cable) and an LED.
If the LED is on, the riser board is receiving power; if off, the riser board is not receiving power.
NOTES: If the Microsoft® Windows NT® operating system is being used, set any Plug and Play expansion cards to legacy mode, using the card
manufacturer’s configuration utility, and enter the card’s resources with this utility. Then run the ICU and add the card to the system’s
configuration.
The ICU is not required for the Microsoft Windows® 95 or Windows 98 operating system because the same functions are provided by the Device
Manager.
NOTE: On some versions of this riser board, the P1 connector may be in a different location. This does not change or in any way affect the
functionality of this board.
