Appendix A. Avoiding Hardware Conflicts
This appendix, listing the default and optional hardware settings,
describes how to avoid system resource conflicts. It also describes
how to do a network remote program load and how to start the
computer from an ATA PC Card.
Avoiding System Resource Conflicts
When a new option such as a PC Card is installed, the computer
might not operate correctly because of conflicting settings for IRQ
(interrupt) levels, I/O addresses, DMA channels, and memory
addresses.
To avoid these resource conflicts, you must know the hardware
requirements, such as IRQ level and I/O addresses, for each option
and program as shown in their manuals.

Then you must check the current resource allocations for the
computer and your expansion unit, and select the available resource
values by using the ThinkPad Features program.
When you want to install a new Ethernet PC Card in the computer,
you need to assign an IRQ for the PC Card. An Ethernet PC Card
generally requires IRQ5 as a default interrupt level; however, IRQ5
has already been occupied by the audio device in the computer.
You need to change the IRQ for the audio device when you use the
Ethernet PC Card as follows:
1. Install the Ethernet PC Card in the PC Card slot.
2. Open the ThinkPad Features program and click on the audio
icon.
3. Click on the Advanced button.
Select the appropriate IRQ not to conflict to other devices in the
Advanced Setup dialog and click on OK.

You can see from the list of default settings on page 178 which
system resources are already used by the devices in the computer.
