Appendix A. Avoiding Hardware Conflicts
This appendix describes how to avoid system resource conflicts by
listing the default and optional hardware settings. It also describes
how to do a network remote program load and how to start the
computer from an ATA PC Card.
For PC Card resource conflicts, see “Avoiding PC Card Resource
Conflicts” on page 255.
Avoiding System Resource Conflicts
When a new option such as an adapter 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.
Example:
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 ESS AudioDrive function in the
computer.
You need to disable the ESS AudioDrive function 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
PC Card ( ) icon.
3
Click on the Auto Config button.
