ISA Configuration Utility
The OptiPlex G1 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 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 low-profile computers have 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 the LED is off, the riser board is not
receiving power.

The riser board is offered in two options:

operating system, use the ICU to set any Plug and Play expansion cards to legacy mode, enter each
card’s resources, and then add each card to the system’s configuration.
The ICU is not required for the Microsoft Windows

95 operating system, because the same functions are provided by the Device Manager.
