BIOS (Parte 2)

Power-On-Self-Test

Display error messages:

Se POST não é capaz de configurar a exibição com sucesso, emite um sinal sonoro ou som audível para indicar um sistema de falha. Caso tenha configurado com sucesso o POST, mensagens de erro pode ser exibido na tela. Exibido erros são, em geral, não tão graves como os erros indicados por um bipe códigos.

Embora vídeo pode ter sido configurado corretamente pelo sistema, vídeo ainda não podem trabalhar, e você não será capaz de ver as mensagens de erro na tela. Em caso de problemas você não deve depender apenas do seu monitor. Ao invés disso, você deve usar um Placa de diagnósticos POST para encontrar o problema.
