This appendix describes how to avoid system resource conflicts with 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.
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 docking station, and select the
available resource values by
using the ThinkPad Features program.

ThinkPad Features program:

Example 1:
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 Sound Blaster in the computer. You need to disable the Sound Blaster when you use the Ethernet PC Card as follows:
) icon.
The Sound Blaster has been automatically disabled by the ThinkPad Features program, and the Ethernet PC Card is ready to use.
When you want to disable the Ethernet PC Card and enable
the Sound Blaster,
open the ThinkPad Features program,
click on the Audio (
or
) icon; then
click on the Advanced button.
You can enable the Sound Blaster
in the Audio/Alarm Advanced Setup window.
(Ref #148.)
Example 2:
When you install an ISA adapter card in the docking station, do the following:
)
icon and click on Advanced.
For resource information for the adapter card, see the manual that came with the adapter card.
You can see from the list of default settings
on "List of System Resources"
which system resources are already used by the devices
in the computer.

List of system resources:

When you do a network remote program load (RPL) or start the computer from a PC Card, you must make sure that the system resources used by the PC Card do not conflict with the resources used by other devices.
) icon.
The built-in device in conflict may have been disabled to resolve the resource conflict.
If you are using Windows 3.11, you can set the memory area used by the PC Card as follows:
To do a network remote program load (RPL):
The following are the resources for a token-ring PC Card and an Ethernet PC Card:
IRQ5 is the default setting used by the Sound Blaster emulation. To do an Ethernet PC Card RPL, change the IRQ for the Sound Blaster emulation, or disable it with the ThinkPad Features program or the SB PS2 command.
A window appears at the bottom of the screen for you to select the RPL speed.
To start the computer from an ATA PC Card:
The following are the resources for an ATA PC Card:
| Notes |
|---|
| If you install the IDE hard disk or CD-ROM drive in the docking station such as Dock I, II, or SelectaDock Docking System, IRQ15 is the default setting used by the IDE hard disk or CD-ROM drive. Remove the IDE hard disk or CD-ROM drive to use an ATA PC Card. |
The PC Card (PCMCIA icon) should not be set to follow the computer hard disk drive (HDD-1 icon) in the list. If the HDD-1 icon is already in the drive-startup sequence, click on the Reset icon; then set the sequence so that the PC Card icon is before the HDD-1 icon.
The following table summarizes the available
system resources for the computer and
docking station.
Values in
parentheses are alternative values that are selectable in
the ThinkPad Features program
or application programs.
The default values are highlighted.
