information, see “Configuring PCI devices” in Chapter 2.
An external device connected to the option card is not

Memory Module Problems
The memory count displayed by power-on diagnostics or
the SETUP program is incorrect.
You may have installed the SIMMs incorrectly. They may be
the wrong type or speed, or they may not be inserted all the
way or in the correct sockets. See “Installing Memory Modules
(SIMMs)” in Chapter 4 for more information.
If you have installed a gold-plated SIMM in the sockets, the
socket may have corroded slightly. Remove the SIMM and
clean the gold-plated connector with a pencil eraser; then
reinstall the SIMM.
