ISA Configuration Utility
The GX1 systems offer 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 low-profile computers have a passive riser board, with no PCI-to-PCI bridge.
Midsize Chassis Riser Board
Option 1
Option 2
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 operating system because the same functions are provided by the Device Manager.
