Coduri hex de diagnosticare a computerului

Coduri hex de diagnosticare a computerului sunt generate, dupa cum spuneam in articolele precedente, de BIOS (Basic Imput Output System), la fiecare pornire a sitemului de calcul, cand face verificarea tuturor componentelor hardware existente si afisate de cardul de diagnoza, interpretarea acestora facandu-se dupa o lista de coduri de eroare furnizata de fiecare producator de BIOS inparte. Aceast alista poate fi gasita ori pe site-ul producatorului ori in manualul primit la cumpararea computerului. In articolul precedent am specificat codurile pentru BIOS-ul Award, in randurile de mai jos vom continua cu BIOS-urile PHOENIX, urmand ca in urmatorul articol sa le prezentam si pe cele de la AMI, acestea fiind cele mai raspandite variante de BIOS.
