Beep codes
Fatal errors, which halt the boot process, are communicated through a series of
audible beeps. If AMIBIOS POST can initialize the system video display, it
displays the error message on the screen. Displayed error messages, in most
cases, allow the system to continue to boot. AMIBIOS displayed error
messages are described in Table 6-3.
