Power-On-Self-Test
PÓS-teste consiste de vários initializationroutines e on-board e cartões de expansão, como o vídeo adaptador. Se uma falha for detectada esta pode ser feita conhecido por:
* Uma ou mais audível sinal sonoro, é chamado de beep códigos;
* Uma mensagem de erro apresentada na tela;
* Checkpoint um código, foi enviado para um dos portas de saída do sistema.
Quando todos os testes foram realizados e os componentes tenham sido inicializado, o controlo é transferido para a Int 19h Bootstrap Loader, para carregar o sistema operacional disponível no disco.
Beeps Sonoros
O bip sonoro de erros são utilizados para as condições que ocorrem antes da exibição do vídeo ou para a solução de problemas sem vídeo.Se ocorrer um erro durante o POST antes de o vídeo foi inicializado, você ouvirá um sinal sonoro audível ou séries de bip sonoro, indicando o tipo de erro que tenha ocorrido.
Nota:
Short=Curto
Long=Longo
Pause=Pausa

Beeps Sonoros
| Beeps | Error Message | Description |
| 1 short | DRAM refresh failure | The programmable interrupt timer or programmable interrupt controller has probably failed |
| 2 short | Memory parity error | A memory parity error has occurred in the first 64K of RAM. The RAM chip is probably bad |
| 3 short | Base 64K memory failure | A memory failure has occurred in the first 64K of RAM. The RAM chip is probably bad |
| 4 short | System timer failure | The system clock/timer IC has failed or there is a memory error in the first bank of memory |
| 5 short | Processor error | The system CPU has failed |
| 6 short | Gate A20 failure | The keyboard controller IC has failed, which is not allowing Gate A20 to switch the processor to protected mode. Replace the keyboard controller |
