RI45 PII Self-Test Prior to Booting

When the RI45 PII is powered up, it runs a self–test (POST = Power On Self
Test). If the POST detects a fault, it outputs the sequence of beeps (beep
code) assigned for the fault. Each beep code consists of 2 x 2 sequences.
In addition, the individual self-test steps are output at I/O port 80h. The
optional SafeCard allows these outputs to be displayed in hexadecimal code
at the front of the device.
