BEEP CODES

If a terminal error occurs during POST, the system issues a beep code before attempting to
display the error. Beep codes are useful for identifying the error when the system is unable to
display the error message.
Numeric
Beep Code* Code
1-2-2-3 16h
1-3-1-1 20h
1-3-1-3 22h
1-3-4-1 2C

*Values indicate number and relative length of beep signals. For example, 1-2-2-3 is one long beep,
followed by two short beeps, followed by another two short beeps, and finally three short beeps.
System Configuration Tests
Initiation of the system generation (SYSGEN) process, which
compares the configuration information stored in the CMOS memory
with the actual system. If a discrepancy is found, an error code will
be displayed.
Configures any Plug and Play device detected (either PCI or ISA):
• All PCI devices, and any ISA device necessary for loading the
operating system will be configured for use.
• Any ISA device that is not required for loading the operating
system, will be initialized (prepared for loading of a device driver),
but not fully configured for use.
