C-2 System Resources
VIEWING SYSTEM RESOURCES
Some hardware option installations might require system resources such as interrupt request
(IRQ) lines, direct memory access (DMA) channels, and input/output (I/O) addresses. See
the following procedures to view system resources.
Follow these steps to view system resources:
1.
From the Windows 95 desktop, click the “My Computer” icon with the
right
mouse button.
2.
Click “Properties.” The System Properties box appears.
3.
Click the Device Manager tab.
4.
Double click “Computer.” The Computer Properties box appears and displays the
View Resources folder.
The View Resources folder shows the system resources used by your computer. For
example, it shows a list of interrupts and how they are allocated. If an interrupt is not in the
list, it is available.
CHECKING JUMPER SETTINGS
The following procedure explains how to locate and, if necessary, change jumper settings
when upgrading the processor. See this section to also view factory jumper settings.
CAUTION:
Jumpers are set correctly at the
factor. If the system requires a jumper change,
change only the setting for that condition.
Otherwise, keep the settings at their factory
settings.
WARNING:
The system power must be off
before changing a jumper setting.
1.
Power off and unplug the system and any attached devices.
2.
Remove the system access cover (see Section 3, “Removing the Access Cover”).
3.
Locate the processor host bus frequency jumper (J9C1-C), and processor
frequency jumper (J9C1-D) on the system board (see the following figure).
If required, remove any installed expansion boards to access the jumpers (see
Section 3, “Expansion Board Removal”).
