If you install a memory module that is not compatible with the computer,
beep will sound when you turn on the power. If the module is installed in
slot A, there will be a long beep (1 second) followed by two short beeps (0.5
second each). If the memory module is in slot B, there will be a long beep
followed by four short beeps. If the both memory modules in slot A and slot
