Checking the Installed Devices List
If a device is installed but the icon appears in a gray shade
rather than a dark shade on the basic diagnostics screen,
the device is defective. Reseat the device connectors. If
the symptom remains, replace the device or the system
board. If needed, adjust the contrast control to clearly
distinguish the shades of the icon.
If a device that is not installed appears in a dark shade (for
example, FDD-2 appears in a dark shade when
NO
second FDD is installed), do the following:
1. Replace the first device in the configuration, such as
an FDD-1.
2. If the problem remains, replace the system board.
The Parallel, and Serial icons are always displayed in a
dark shade because the icons represent subsystems of the
system board and not the attachment of the devices.
The FDD-1 and PCMCIA-1 icons represent the drive in the
computer. The FDD-2 and PCMCIA-2 icons represent the
devices in the port replicator or that is attached through the
port replicator.
