Corrective Action and/or Explanation
Serial ports A and B may have been assigned the same IRQ.
Assign a different IRQ to each serial port and save the
configuration.
Check that cache memory and main memory are correctly
set in their sockets.
An error message may be displayed and the PC may "hang"
for 20 seconds and then beep. The POST is probably
checking for a mass storage device which it cannot find and
the PC is in Timeout Mode. After Timeout, run Setup to
check the configuration.
