Chapter 6: Speaker Beep codes
All Tyan motherboards come with a BIOS feature called "beep codes".
What these do is inform you (the user) about potential problems in your
configuration.
These errors can occur during POST (Power On Self Test), which is performed
every time the system is powered on. Fatal errors are communicated through a
series of audible beeps from your computers' speaker. Should an error of this
sort occur, listen carefully to these beeps and match the description from the
table below to determine the source of the problem.
