Chapter 4. Working with Adapters
This chapter provides information and instructions for installing and removing
adapters.
When you are installing or removing adapters, it is important to resolve any
resource conflicts that might arise. For example, if you install an ISA legacy
adapter, you might need to manually configure the adapter by setting a variety of
switches on the adapter and by using the Configuration/Setup Utility program.
Many adapters now use Plug and Play technology which enables the computer to
automatically configure the adapter, provided that the required resources are
available. Refer to the instructions that come with your adapter to determine if it is
Plug and Play. For more information, see “Adapter Configuration” on page 26.

Ÿ
The following size restrictions apply to new adapters:
– In the 3-bay design, adapters longer than 17.78 cm (7.0 in.) cannot be
installed.
– In the 4-bay design, adapters longer than 17.78 mm (7.0 in.) cannot be
installed in expansion slot 1. Also, adapters longer than 20.32 cm
(8.0 in.) cannot be installed in expansion slot 4.
Ÿ
If you have the 3-bay design, the power supply does not support 25 W
adapters installed in both expansion slots.
Ÿ
You can install a graphics (video) adapter in your computer. If the graphics
adapter is an ISA adapter, the base ROM (read-only memory) is located at
C0000H.
Each time the computer is started, it searches for a graphics adapter installed
in either an ISA or PCI slot. If the computer detects a graphics adapter, the
video subsystem integrated in the system board is not enabled. No jumpers
on the system board need to be changed if a graphics adapter is installed.
Ÿ
If you want to install a non-graphics ISA adapter, ensure that the base ROM
address is not located at C0000H. Otherwise, the computer will recognize
this as a graphics adapter and will not enable the video subsystem.
