Toshiba Satellite 4030CDT - Plug and Play

If Something Goes Wrong
Resolving a hardware conflict
to bypass the microprocessor and access memory directly. If two
or more devices use the same DMA, the data required by one
device overwrites the data required by the other, causing a hard
ware conflict.
Plug and Play
With Plug and Play and Windows 98, avoiding hardware conflicts
is easy. Plug and Play is a computer standard that helps the system
BIOS (basic input/output system) and Windows 98 to automati
cally assign system resources to Plug and Play-compliant devices.
In theory, if every device connected to the computer is Plug and
Play-compliant, no two devices will compete for the same system
resources. You simply plug in the device and turn on your com
puter. Windows 98 automatically sets up your system to
accommodate the new device.
However, if you install an older (legacy) device that Windows 98
cannot recognize, Windows 98 may have difficulty assigning sys
tem resources to it. As a result, a hardware conflict can occur. To
see what resources Windows 98 has assigned to the device, see
"Checking device properties" on page 142.
Resolving conflicts
There are three things you can do to resolve hardware conflicts:
♦ Disable the device.
For an older device, remove it from the computer. For a Plug
and Play device, see the next section, "Fixing a problem with
Device Manager" on page 142.
♦ Disable another system component and use its resources for
the new device. Refer to the next section, "Fixing a problem
with Device Manager" on page 142.
♦ Reconfigure the device so that its requirements do not conflict.
Refer to the device's documentation for instructions about
changing settings on the device.
